OpenStreetMappers are a diverse group of people. This short segment will introduce you to another person that makes the project what it is. Enjoy this little break from longer talks and get to know a conference delegate that you can talk to at the conference. As OpenStreetMap is made by us all, it's important to get to know each other and this can form a nice ice-breaker or give you suggestions on conversation starters. Gregory has two unique OpenStreetMappers for us to meet and chat to. One has only been a member of the project for a couple of years, getting involved due to a call from the Humanitarian OpenStreetMap Team(HOT) but also some local projects to map solar panels. The other OSMer has been involved for more years, and has started running out of new things to map in her local area so helps the project in other ways. about this event: https://2020.stateofthemap.org/sessions/FZCM39/

Do you get together with other mappers in your town? Would your group benefit from a bit more support? In this talk you will learn about the newly reformed Local Chapters & Communities Working group and our effort to support mapping groups all over the world. Attend this talk to learn more about the Local Chapters and Communities Working Group (LCCWG). This talk will share our current initiatives as well as invite ideas from participants, and will precede the annual Local Chapters Congress, so hopefully we'll see you at both! Who are the Local Chapters & Communities Working Group? Reformed in November 2019, the LCCWG are a small group of OpenStreetMap enthusiasts and community leaders interested in finding and implementing ways for the Foundation to support the growth of local communities. The LCCWG hopes to facilitate a global exchange of ideas and support among local leaders, and work together to create strong local communities. Right now we have 3 focus areas: building local community cohesion, sharing ideas and best practices globally. We hope to encourage established communities to further organise themselves and eventually formally affiliate with the Foundation as one of its Local Chapters. We will review the role of Local Chapters within the Foundation and the interactions between them. Based on our findings we will make recommendations to the Board as to how the affiliation scheme can be improved to provide a stronger case for local communities to eventually become Local Chapters, or possibly suggest creating new affiliation models such as less-formal user groups. Interested in representing your community on the Working Group? Start by joining the conversation today!

In Cusco, Peru, during the last 2 years, GAL Center worked with students using OSM and associated tools, such as Kobo as educational tools, mainly for research into social problems that the students themselves identify in their locality. Projects such as “Sexist advertising mapping”, “Sexual health” and “Garbage mapping in Larapa” were the result of this work. This year, MapImpact is one of the HOT Microgrants and we will work with high school students and YouthMappers Chapters that we help to create in universities. In this talk, I will tell you more about how we work MapImpact in GAL: our objectives, our methodology, our results and why we would like it to be replicated in other places. MapImpact is a GAL Center project in Cusco, Peru, which aims to make more students aware of the problems that afflict their locality, to achieve this they will have to investigate these problems using OSM and associated tools such as Kobo Collect, as the main research tool. To develop this project GAL had a previous experience of 2 years, in which we work with high school students in different provinces of Cusco and help in the creation of the first YouthMappers Chapters in Peru, projects such as “Sexist advertising mapping”, “Sexual health” and “Garbage mapping in Larapa” were the result of this work. This year we will work MapImpact also with university students and our intention is for students to understand digital maps not only as a tool to generate geospatial data, but also as a tool of social impact, that is, the process not end when they save the changes in OSM, they have to use that information to make visible a problem that afflicts their location. In this talk we would like to share with you the whole process we follow to reach this point. about this event: https://2020.stateofthemap.org/sessions/3AJAEF/

We have seen an explosion of OSM mapping in the last few years around maps for development and humanitarian uses, particularly in Africa. During this time it has also become clear that sustaining this essential mapping work, and keeping maps up to date, was going to be a primary concern. Building a healthy mapping ecosystem around mapping for development will not necessarily be able to follow the same model as it has in more developed countries. In this talk, I will share the culmination of my research on sustainability with the World Bank’s Global Facility for Disaster Reduction and Recovery and their Open Cities Africa project, and some ways that we can best support mappers and grow a healthier global OSM ecosystem. Two years ago, at SOTM in Milan, I and several colleagues held a panel discussion around sustainability challenges that were common to working with OSM in developing countries. Mappers spoke up about their struggles continuing to map, keeping maps up to date, and growing their mapper communities in places with very few resources. This research has now concluded with a white paper on the topic, and many new learnings along the way. In this talk, I’ll review the outcomes of "Sustainability in OpenStreetMap", https://opendri.org/resource/sustainability-in-openstreetmap/, a publication under OpenDRI at the World Bank. While many groups and projects are arising to do mapping throughout the world, and many for a social purpose, we found a number of challenges to keeping mapping moving forward and overcoming hurdles. These include financial, technological, social, and political challenges, each with its own kind of possible solutions. I also looked into the varieties of OSM actors that would be most likely found in contexts of OSM in development, and what challenges they each may face. These actors include governmental mappers, independent consultants, businesses and startups, nonprofit organizations of a wide variety, international NGOs, formal and informal chapters, and more. Finally, I identified some solutions and supports that are most needed to create a sustainable OSM environment in low-resource geographies. In this talk I will share about all of these findings, and we will discuss the best ways to support a strong international mapper ecosystem. about this event: https://2020.stateofthemap.org/sessions/XAKBJT/

Want a postcard? Looking for somebody to send a postcard to? Me too! Let's discuss how people in OpenStreetMap come together, which pleasant and otherwise experiences we had meeting other mappers, and how to express gratitude and make people feel a bit closer to each other — with postcards. Each time I visit a SotM conference far from home, I'm collecting postal addresses from everyone who follows my news channel. And I send postcards: "Hello from Aizuwakamatsu!" We rely on digital too much: nothing we can touch, nothing we can put on a shelf. Virtual maps, virtual gratitude. With this project, OSM postcrossing, I plan to give every mapper a chance to have something tangible as an outcome of participating in our project. But to get there, we must think of what brings us here, and what experiences we have as members of the community. The premise is simple: ask somebody for their postal address. Except people are reluctant to give it: the address is a private information, and privacy is important. Have you tried to upload a gpx trace, to see how we value it? A lot. So what do you do? Do you send a postcard to a random mapper? Do you publish your address for everyone to see? Should you stay back from the official real-world services and back away to the comfort of virtuality? about this event: https://2020.stateofthemap.org/sessions/CKYTVS/

How I used OSM data to visualize gender disparity in street names for all of Brazil. The result shows how women are underrepresented in street names in the country, and raises questions on who is chosen to be commemorated in street names. Using OSM road data and a database of gender popularity for names, I created a map visualization to show gender disparity in street names in Brazil. Streets named after women represent only a small proportion of the streets in Brazil. This proportion is even smaller when we consider the length instead of the number of streets. In Brazil, streets are typically named after prominent historical figures, including politicians, business people, military, religious figures, artists, and academics, among others. The small representation of women among these reveals who is chosen to be regarded as prominent, and thus commemorated in a street name, and who isn't. Another interesting aspect is that the map allows up to see certain areas and neighborhoods where female street names predominate. Upon quick visual examination, these appear to be usually in neighborhoods at the periphery of large cities. More in-depth research could indicate if there's a spatial pattern here and if it is related to other social phenomena. The interactive map was based on the Road Orientations Map by Vladimir Agafonkin. I used Mapbox and mbtiles for the map visualization. To process the source data, I used Geofabrik extracts of OSM data and Postgres / PostGIS scripts. The interactive map is here https://medidasp.com/projetos/genero-ruas/#12/-23.5617/-46.6469 and the github repo is here https://github.com/bplmp/genero-ruas-mapa about this event: https://2020.stateofthemap.org/sessions/HLFEER/

Map Kibera has been working for the past two years with some of Kenya’s county governments to create maps of their primary features and funded projects. After implementing a Participatory Budgeting process, these counties realized that without good maps it was difficult for people to not only allocate resources, but to work with citizens to identify needs and prioritize funds. Map Kibera has been assisting counties to map key features and projects in OSM by working with youth from the local communities. The maps not only serve to connect citizens to the budgeting process and hold county government accountable for the funded projects, but, they have also become central to county functions in all areas. This talk will share all about the process used and outcomes. Map Kibera has been helping communities map out their local projects by collecting data and creating digital maps that they can use for planning and decision making. The Participatory Budget Mapping project was conducted in 3 counties in Kenya: West Pokot, Baringo and Makueni. These counties had already been part of an annual process of participatory budgeting, with locals weighing in on how budgets should be spent in their counties. In early 2018, Map Kibera along with partner GroundTruth Initiative began working with the World Bank in Kenya to initiate Community Participatory Mapping, by training the local citizens on how to map their county-funded projects using OpenStreetMap, Open Data Kit, and Kobo Toolbox. The project also enabled citizens to track the progress and quality of those projects, allowing them to hold the government accountable for delivering what had been promised during the budgeting sessions. The results of the mapping are displayed on a dedicated website and printed maps for budgeting sessions, which often take place in rural villages. The project has been able to: 1. Visualize existing and/or new government-funded (county and national level) development projects which will enable the counties to know which projects have been completed, which are in progress and the projects that are pending. 2. Perform a needs assessment analysis through the Participatory Budget meetings where the counties engage the citizens and together determine the distributions of the projects. 3. Assist citizens to monitor progress of projects and hold the government accountable for delivering on its promises. 4. Transfer knowledge of mapping in OSM to county government representatives directly, in offices of M&E, GIS, ICT, and Budgeting. Using OpenStreetMap and sharing the data with the counties is a huge milestone for Map Kibera as this will encourage more institutions and people using OpenStreetMap within both communities and county government. This session will share the process and tools being used in the project and early outcomes. about this event: https://2020.stateofthemap.org/sessions/LDGZ37/

The talk will focus on the Turkish law egulating the acquisition, collection, dissemination and trading of spatial data falling within the responsibility matrix of Turkish National Geographic Information System, effective since February 20, 2020. With the law, acquisition, collection, dissemination and trading of spatial data which is defined within the National Spatial Data Responsibility Matrix by third party individuals or legal entities are subject to prior application fees and approval of the Ministry of Environmental and Urban Affairs. The talk will reflect and report the developments in Turkey after the law, effects and implications drawn focusing on the national spatial sector, OSM, and the Turkish OSM community. On January 30, members of the Turkish parliament voted in favour of the proposed amendment to the law regulating the acquisition, collection, dissemination and trading of spatial data falling within the responsibility matrix of Turkish National Geographic Information System. The law has officially been put into practice on February 20, with nationwide uncertainties on how it will be enforced, and on what level. With the law, the sole responsibility and authority on the national spatial data index is given to the Ministry of Environmental and Urban Affairs. Acquisition, collection, dissemination and trading of spatial data which is defined within the National Spatial Data Responsibility Matrix by third party individuals or legal entities are subject to prior approval of the ministry. Moreover, the approval will be subject to a fee of 25₺ for native, 50₺ for foreign parties per each 1/1000 plan corresponding to the study region(s) from the national topographical grid.

This talk with survey the bright and dark history of companies and professional involvement in OpenStreetMap, lay out the challenges that we face now, and chart steps forward to figuring this out together. I want to reset the vision of the position of companies in OSM, starting by connecting back in time to when it was all more fluid in our community. Only later did some draw a sharp distinction between volunteer and professional activities in our project. The reality of the relationship of companies and professionals in OpenStreetMap from the very earliest days until today is ... complicated. There's incredible mutual benefit and purpose. There are super hard issues to address when large amounts of resources are mustered, among the constellation of many kinds of actors and motivations in OpenStreetMap. The reality is that OpenStreetMap is transformative, and that companies in OSM first come for the data, may fumble along the way, and stay for the shared mission to change how maps are made in the open. I want to reset the vision of companies place in OSM, starting by connecting back in time to when it was all more fluid in our community. For example, a month after I met Steve Coast in 2005, I was setting up meetings with Google. Helped secure Yahoo! maps imagery in 2007. Companies hosted many of the early days mapping parties. Professional cartographers were among the projects most original enthusiasts. The point was to change how mapping was done -- including and especially at companies. Only later did some draw a sharp distinction between volunteer and professional activities in our project. The reality of the relationship of companies and professionals in OpenStreetMap from the very earliest days until today is ... complicated. There's incredible mutual benefit and purpose. There are super hard issues to address when large amounts of resources are mustered, among the constellation of many kinds of actors and motivations in OpenStreetMap, whether they be hobbyists, developers, students, researchers, non-profits and on and on. The reality is that OpenStreetMap is transformative, and that companies in OSM first come for the data, then stay for the mission. There are of course fumbles along the way. But as a community we've lacked a way to take a clear eyed view of the challenges and vital role companies and professionals have played in what OSM has become today. In part that fault lies with companies themselves, who are risk averse to delving into our wild and wooly communications. Those that do, can take a lot of heat.

When people come to OpenStreetMap for the first time, their expectations are sometimes at odds with what the OpenStreetMap community is doing. If you have been puzzled by an OSMer telling you that OpenStreetMap is not a map, that openstreetmap.org is not aiming to compete with Google Maps, or by their stubborn refusal to remove a private trail from the map, then this talk is for you. It will explain the basic tenets of the OpenStreetMap community and how they apply in practice. This talk will explain some of the often-heard but little-documented basic concepts in OSM, like * we are not a map (but a database) * the map does not matter (the community does) * openstreetmap.org is not aimed at the public (but at mappers) * we map what's on the ground (not what the government or the landowner wants) Building on that, the talk will also outline why the OSM community is often skeptical about filling an empty map with data imports, about AI contributions, or about automatic edits, and why OpenStreetMap is not a business directory. The plan is to explain the basic ideas and give examples of their effects for data users or for everyday mapping practice. Where the concepts are controversial or subject to discussion, these controversies will be mentioned but not followed in depth. This talk will focus on "traditional" values in OpenStreetMap because they are omnipresent. After hearing these explanations, newcomers will have a better chance of understanding where people come from when they say things like "we are not a map", and will be better prepared to form their own opinion. about this event: https://2020.stateofthemap.org/sessions/DYXWDC/

Current presentation aspires to contribute to an overall assessment of the OSM map in Athens, Greece. The OSM content is assessed in terms of completeness and precision. Various official mapping sources and ground truth data are employed in order to measure the current state of the map. Current research aspires to contribute to the assessment of the OSM map in Athens, Greece in terms of completeness and precision. The researcher chose Athens as, according to international published research regarding the phenomenon of Volunteered Geographic Information, it is initially assumed that it will have the maximum quality level, as Athens is the most populated city of the country. The analysis includes mainly quantitative evaluation methods. To the level that access to editable - data is feasible, various GIS techniques are employed while in other cases the assessment is performed through samples in various regions of the municipality. While evaluating, all the known properties and characteristics of Volunteered Geographic Information are considered. Eventually, a short discussion related to similarities and differencies from other published OSM assessments in other countries, completes this short initial presentation. Apart from official mapping sources, ground truth data, collected through the use of in-car GPS devices, in certain areas of the city, are providing valuable insights regarding the level of quality. The research focuses on certain geographic entities, including the geometry of the road network, the street naming and addressing, various administrative units, some building footprints, parks and POIs. about this event: https://2020.stateofthemap.org/sessions/V9J9JS/

Humanitarian Openstreetmap Team (HOT) is an international team focused on humanitarian action and community development through open mapping. Since 2010, the organization has managed activations to attend multiple events such as understanding hazards, public health, refugee response, among others. However, when we think about organizing large-scale efforts it can be complex, due to the necessary logistics, volunteers involved, and also assuring that the data collected is meaningful. MapCampaigner, is a tool which monitors progress, view metrics on the quality and completeness of collected data and users engaged. The goal of this talk is to present the latest features included in the latest update of the tool, the goals that MapCampaigner accomplishes and many humanitarian and non-humanitarian examples through a demo. When we talk about a mapping campaign, it generally has specific characteristics: Desire to collect geospatial data for a purpose. Define an area of interest. Define a set of features and attributes to collect. The period of time of the campaign Group of people to collect the data. Could be highly trained staff members or volunteers. It would sound simple. However, it is possible to find challenges in difficult places. For instance, how to crowdsource precise locations and specific attributes of every school in Barranquilla, Colombia? Because some locations are inaccessible, it becomes difficult and costly to deploy people to the area to collect and validate the data. Many tools have been developed to address these challenges remotely, like OpenMapKit and Maps.me to collect data and do some quality assurance with JOSM, for instance. Despite this, these tools do not have the property to monitor specific features/attributes, define current status of the mapping campaign, or validate people contributing in an area. Putting these challenges in mind, HOT designed the MapCampaigner tool. Users can track and measure the quality of many features such as schools, buildings and cafes at the same time. This mapping campaign will report users involved, missing tags, and percentage of completeness in an area for each attribute collected. Also, MapCampaigner has integrations with apps such as Maps.me and OpenMapKit In this talk, I will walk through the tool, how it is used, and seek input for enhancements. Will show new features included in the latest user-centered redesign using live demo. The schedule of this talk is the following: Introduction and problem statement (5 minutes). MapCampaigner features (5 minutes) Examples and demo (5 minutes) Conclusions and future work (5 minutes) about this event: https://2020.stateofthemap.org/sessions/VJS3LC/

We built open-source infrastructure that allows the community to integrate open data reviews of POI into the OpenStreetMap ecosystem. This enables any application or website to make use of a reviews layer, and to benefit from the shared data pool that is created by a combined user base of participating applications. We built it to ensure that people all over the world can freely share their insights about things that matter to them without being confined to proprietary data silos. Mangrove is a non-profit initiative to create a public space on the Internet where people can freely share insights with each other and make better decisions based on open data. Our goal is to create an Open Data Ecosystem for Reviews of places, companies, websites, books, and more. We built open-source infrastructure that enables any application or website to integrate a reviews layer, and to benefit from the shared data pool that is created by a combined user base of participating applications. In this talk, we are going to introduce to the OpenStreetMap community the technology that is available, and we are going to show how OSM-based projects could benefit from an integration with Mangrove. Furthermore, we are introducing the non-profit Open Reviews Association, ORA, who became the custodian of the Mangrove technology and open dataset. We invite anyone to join as a member in order to shape the direction of the project and help achieve its vision. about this event: https://2020.stateofthemap.org/sessions/AA8RXP/

Le Togo, l’un des plus petits pays de l’Afrique de l’Ouest abrite depuis 2013 une communauté OpenStreetMap. OSM Togo a mise en œuvre de nombreux projets mais a connu également des difficultés. Cette présentation a pour objectif de faire un aperçu sur la vie de la communauté OpenStreetMap Togo. OpenStreetMap (OSM) considered as the wikipedia of cartography is a Collaborative Mapping Project which exists in several countries around the world. So, Togo, one of the smallest countries of West Africa, has been hosting for more than five years a strong and dynamic OSM community called OpenStreetMap Togo. Several activities, mainly mapathon sessions, mapping parties, and capacity building trainings have been carried out through several projects for various target groups including students, public institutions, civil society organizations, and companies in order to promote the OSM project and to have a quality data on Togo. Highlights of these projects are: "Digital mapping OpenStreetMap as lever for local development in Togo", “GirlsMap, a gender-oriented project implemented in several African countries”, “G roads project (mapping of mainly roads of Togo)”, and “mapping of all pharmacy of Lomé, capital of Togo (CARTOPHARMA)”. Today, there are more than 200 local contributors who, through their actions, are making the OSM data evolve at the country level. However, like in most OSM communities in Africa and around the world, OSM Togo is sometimes constrained by several difficulties that limit the expansion of the OSM project and the production of better quality data in Togo. The objective of this presentation is to highlight the life of the OSM community in Togo, its projects, strengths, challenges and its difficulties related to quality OSM data production. about this event: https://2020.stateofthemap.org/sessions/EYMZXV/

This talk will present the results of a survey done on the State of the OpenStreetMap, the unique challenges and success of OSM in Africa and how the different communities are working together to grow the map and the community on the continent. The global State of the Map conference is taking place in Africa for the very first time, and it is a great opportunity to light a torch into the state of OpenStreetMap in Africa. What is happening around the Map the West, Central, South and North of Africa? Where are the active communities, what are the reasons for their success, what challenges are they facing and what solutions are they using to overcome the challenges? This talk will present the results of a survey done with different OSM communities in Africa to answer the above questions, while at the same time looking at the map data to measure the level of completeness in each country, and examining the reasons behind the different scenarios in the different countries. The talk will also present the views of OSM Community leaders from Africa on how to promote sustainability, resilience, inclusiveness, diversity and equity in decision making in regards to the future of OpenStreetMap. Why are there very few official local OpenStreetMap Chapters from Africa and what can be done to change the situation? about this event: https://2020.stateofthemap.org/sessions/M9WYW9/

Mobile mapping is the process of collecting geospatial data from a mobile vehicle using a 360º camera, laser scanner, GPS/IMU positioning system, and other sensors. Mobile mapping is a time and cost-effective way to conduct asset inventory, monitor road infrastructure, and map street furniture. However, the high cost of acquiring mobile mapping equipment, such as professional 360° cameras and laser scanners, inhibit the ability of local OpenStreetMap communities to leverage mobile mapping technologies. With advice from Mapillary, low-cost devices that are accessible to communities make mobile mapping possible on a wider scale. 360º cameras may be used in different vehicle types: cars, bicycles, quad bikes and also on foot. With a 360º field of view, these cameras capture everything around the sphere. Where flat frame images can limit the map editing workflow, 360º images bring panoramic viewing to OpenStreetMap editors for a more comprehensive understanding of the space and place. The Mapillary photo overlay supports panorama view on OSM ID Editor and JOSM. After images have been captured and uploaded to the web, Mapillary creates a reconstruction of the scene in 3D using an open-source Structure from Motion library (OpenSfM). This helps to improve the image GPS positions, based on the overall consistency of the 3D scene. Next, the objects in the imagery (such as traffic signs and other types of objects) are identified by computer vision. Combining detections of an object in several images and the aforementioned 3D model allows us to calculate the position of the detected object in the world. Overall, this talk will examine the recommended 360º cameras, discuss data collection and benefit of street-level imagery collection with 360º cameras, review strategies for uploading 360º images, comparing different 360º camera models, and highlight how OpenStreetMap communities around the world are using 360º images to improve local maps with Mapillary. about this event: https://2020.stateofthemap.org/sessions/YTHZWC/

What are the perspectives and challenges around the new wealth of building data in OpenStreetMap? OpenStreetMap (OSM) is constantly expanding into emerging fields, particularly around building datasets. Through its participatory character, OSM provides an incomplete, but global coverage of buildings, nowadays already outnumbering roads. Their distribution and properties are the best indicator to population density, economic activity patterns, and risks of natural hazards. Thus, OSM constitutes a perfect base to provide answers to many related questions of various stakeholders from communities, governments, private sector and research. We present an overview of how worldwide building data is used and will be in the near future. We will guide through our latest projects, reaching from the creation of risk models, via automated building extraction from satellite sensor data to building completeness estimates, and set these developments in context with other community-driven activities. We report on the challenges of managing global building data, and combining attributes from other open and public domain big datasets towards rich handling of building data in and around OSM. A special focus is on the ways how this new information can be made useful to support mappers to achieve higher completeness of building data. about this event: https://2020.stateofthemap.org/sessions/YXNWNT/

Crowd2Map Tanzania is a volunteer run crowdsourced project that has been mapping rural Tanzania since 2015. This talk will give an overview of some of the lessons learnt, particularly in building mapping communities in remote rural areas with first time smartphone users. Since 2015, we have been adding schools, hospitals, roads, buildings and villages to OpenStreetMap with the help of over 12500 volunteers worldwide and 600 on the ground in Tanzania. With minimal budget and no staff we have so far added over 4.1 million buildings and trained community mappers in 26 areas of Tanzania. We were asked to run a mapathon at the United Nations General Assembly in October 2018 and have also been featured in many newspaper articles. We have prioritised mapping those areas of Tanzania where girls are at risk of Female Genital Mutilation, FGM, so that activists and the police can more easily find and protect them. But we have also been working with other community groups and district officials on how maps of their area can help with development. The mapping is in two phases – firstly online volunteers trace roads and buildings from satellite images then volunteers on the ground add names of villages, offices, churches, shops and other points of interest using a free smartphone app Maps.Me and we then produce printable maps of villages, wards and districts, and train people about how they can use these maps. Training field mappers who have never been online, seen a map of their village, or used a smartphone before has multiple challenges. This talk will outline some of them, and lessons learnt, and seek to stimulate a discussion from the wider community on sharing good practice and resources in this area. about this event: https://2020.stateofthemap.org/sessions/DZ8PWQ/

Separation of features by their importance is a core technique in cartography. But what happens if features of the same feature class (e.g. train stations) have a varying importance? A manual cartographer can choose the important features based on other knowledge. Howerver, rule based cartography which is dominating in the OpenStreetMap environment cannot work this way. A computer programme rendering a map needs selection rules. Someone has to implement them. This talk presents some examples showing how to add lacking relevance information if the importance of features within one feature class ranges span between extreme values. It will show how train stations and airports can ranked using other OSM data and external datasets. Maps cannot show all information at all scales. A cartographer needs to decided which features should appear at which scale on the map. OpenStreetMap based web maps are usually products of rule-based cartography, a computer programme selecting features from a data store and rendering them. It needs rules. If all the features of a feature class are of similar importance, the selection is simple. If not, ranks or attributes to be used for ranking are required. Ranks are assigned to roads as values of the `highway=*` tag, rankable attributes are available as `population=*` tags in OpenStreetMap. In some cases some features of a feature class are of high importance but many other features of that class are irrelevant at medium or lower scales. For example, a map on a medium scale cannot show all stations or all airports in a country. Some airports are only used by a few flights per day, others are not even public. Some train stations have dozens of trains per hours while others get served only few times per week or are used by a dozen passengers per week. Important features should appear at country level but irrelevant features should appear at high scales only. This challenge has not been addressed by map styles used for OpenStreetMap data so far. Authors of map styles circumvent the issue by rendering all features at higher scales only or by selectiong features randomly until enough features are rendered. The talk will present how to add ranking information to train stations and airports from OpenStreetMap using other OpenStreetMap data and/or external datasets. The ranking is applied in the rendering database. The ranking train station is based on the presence of public transport route relations and has been used for train station rendering of OpenRailwayMap's infrastructure map style since January 2020. about this event: https://2020.stateofthemap.org/sessions/3FNPY7/

This talk is based on the experiences I faced while working with the public sector on mapping and try to identify some of the impacts that made and answering 3 questions which arise: * How much Money should I spend? * How much Accuracy do I need? * How much Human Involvement? In this talk, I will be explaining experiences faced while working on some of the major projects in public sector related to FOSSGIS and where all we could implement OSM into. Some of the major projects are as: ##### Utility mapping of State Electricity Board: Comprehensive solution for mapping was developed for Kerala State Electricity Board. The solution included a. Mobile field survey and mapping tool b. Map editor for post production and drawing c. Map viewer d. Map printing e. various intermediate data processing and conversion tools. Complete tool chain was designed and field tested. KSEB used our approach to map 11Kv electric poles of distribution department. This covered around 14 Lakhs electric poles. The original cost estimate for the work by KSEB using traditional approach and proprietary systems was around Rs 200 crores. Technological solution developed by ICFOSS will dramatically reduce cost of mapping and lead to substantial saving of public exchequer. The benefit through utilisation of the map data like electricity loss minimisation and quality improvement is also to be noted. For the original price, work would not have happened. The entire process was based on technologies and standards around OpenStreetMap. ##### Participatory mapping of Govt. Offices Government of Kerala aims to build a spatial database of whole Kerala based on OpenStreetMap. A participatory model was planned for the field survey and the execution was planned in different phases; Government Institutions mapping, Road and Waterways mapping, etc. As preliminary phase, govt. Offices mapping was done by developing an HTML5 based Laravel web application. And this will be later on validated and uploaded to OSM. ##### Route analysis for Govt. Fiber Optic Network A dedicated Optic Fibre Network (Kerala state Fibre Optic Network) connecting 30000 of Government Institutions including schools and other departments was planned. Substations of KSEB (Kerala State Electricity Board) across the state were chosen to create the backbone network installing PoPs (Point of Presence) at each substation. As part of the planning phase, total length of fibre cable required was to be found. Based on GIS based routing techniques and derived methodologies, cluster of networks and total length estimate were identified. ##### Canal digitisation within 42 sq.km. paddy area Government of Kerala aims to map canal system within Thrissur Kole Wetlands an area of around 4300 hectares to measure total water holding capacity of the system. A drone based aerial survey model was planned for the data collection and further digitisation and volume measurements were done using OpenDroneMap and OpenStreetMap based toolchain. about this event: https://2020.stateofthemap.org/sessions/3DMDQK/

The talk is to basically share the experience of working with Imports of Health Facilities in India (OpenGovernmentData). We planned to go briefly through the background of Open GovernmentData and the countries following the OGD, along with the compatibility of OdBL for the datasets they provide to the public. The main purpose of the import is to provide accessible data of accurate health care information from the Open Government Data directories for Hospitals, Health facilities, Blood banks, Health Centers and Health Clinics information which can be useful for all the people and also the Humanitarian team in India. The primary focus of the talk is the import process from data preparation to the execution which includesImports Guidelines , Data Cleanup, Data transformation, Data Execution. The talk shares the detailed stats of the - Indian Health facilities OSM map data coverage before & after Imports and our survey experience for collecting the health facilities records in our region - Telangana. We also line up with the Survey experience to collect the Health facilities records and conducted OSM awareness programmes. Conclude the session with the future plan and local community support. We RMSI Team is performing the imports of Healthfacilities in India for OpenGovernmentData. We want to share the experience working on our successful imports from planning to importing the data. Also want to share the usage of Open Government Data and the other countries who are following the same. In total we have 190k+ records in the datasets which have been provided by the government of India and among them 46k+ are already on OSM. he talk is to basically share the experience of working with Imports of Health Facilities in India (OpenGovernmentData). https://wiki.openstreetmap.org/wiki/India_Health_Facilities_Import The main purpose of the import is to provide accessible data of accurate health care information from the Open Government Data directories for Hospitals, Health facilities, Blood banks, Health Centers and Health Clinics information which can be useful for all the people and also the Humanitarian team in India.

This talk will present an evaluation of different OSM routing software and its impact on the journey. Several popular OSM routing software results will be evaluated on its route-cost (distance and or time) and different modes of transportation (from walking to motor-vehicle). Additional evaluation on the ground will also evaluate which route is a good (or bad) one and what may cause this impact. There have been multiples OSM routing services that are available, from offline to online. While this situation gives people many options to choose from it may also confuse people on which service they should choose or use. This talk is an effort to evaluate these services on different modes of transportation. The evaluation is not only on the routing result but also on when the route is used in real-life scenarios. It tries to answer practical questions such as what is the routing service that provides the best result for walking? Or is it better to use Graphopper or OSRM for car navigation? Different OSM routing services will be evaluated using several start-end points and what do the results look like. How do different routing service results in shorter or longer distance/time and what may have caused it? Surely the journey in the real situation will be presented as well. While the answers highly depend on several factors (such as road tag completeness, local road rules, and time of traveling), this talk will be a good overview for the audience that wants to know more about routing services in OSM. No technical knowledge is necessary. about this event: https://2020.stateofthemap.org/sessions/MJ8ZY8/

Last year, HOT collaborated with OSM Liberia and iLab Liberia to complete the mapping and perform quality assurance in four counties in Liberia. The objective of this program is to update OpenStreetMap data to assist with a Social Registry data collection in four counties in Liberia: Bomi, Bong, Nimba and Maryland. Buildings and roads are the entities to map for this program. The Government of Liberia is working on building an effective social protection by implementing a Liberia Household Social Registry (LHSR). The data collection for this Liberia Household Social Registry (LHSR) requires house-to-house visits. To ensure that the data intake questionnaire is administered to all households, updated map is needed since it’s last updated in 2008. HOT collaborated with OSM Liberia and iLab Liberia to complete the mapping and perform quality assurance in four counties in Liberia. The objective of this program is to update OpenStreetMap data to assist with a Social Registry data collection in four counties in Liberia: Bomi, Bong, Nimba and Maryland. Buildings and roads are the entities to map for this program. The mapping itself is done by local university students. After completed mapping all four counties, they perform data validation using JOSM. Then, the data is being validated again by OSM Liberia, iLab Liberia and HOT ID. Lessons learned from this digitization program are: - First, it’s really great to involve local mappers because they have local knowledge especially on mapping roads. The road’s classification in Africa is quite different, they even have their own OSM Wiki Page. - Second, it’s really useful to review the works of mappers while they’re mapping, so that we can point out if there is any mistake. We can also make a guideline out of this mistake we found, so that they don’t do it again in the future. - Last, it’s better to make new mappers get familiar with mapping first before jumping to data validation. The longer duration of mapping, the better validator they would become. Though it can be helped by providing a validation guideline, it’s better for them to understand the do’s and the dont’s, what’s right or wrong, what’s supposed to do and not to do when mapping basic objects like buildings and roads. To grasp this level of understanding requires some time of mapping. We still find warnings, errors, conflicts and unfixed geometry in the tasks validated by local university students. Yes, this world would be better if there are more validators, but it takes some mapping time to be a good validator, to understand what needs to be corrected and what’s not. about this event: https://pretalx.com/sotm2020/talk/KDXFHZ/

Drone technology is an evolving industry used in multi-disciplinary fields ranging from agriculture, marine conservation to real estate and films. There’s so much potential and possibilities on what drones could help people making work faster and more efficient. In mapping, aerial imagery uploaded to Open Aerial Map can be used as basemap for OSM editing. Example cases are in Batad Rice Terraces, UNESCO Heritage site for mapping tangible changes in the community over time and create a tourism map and other small urban communities in the Philippines, aerial imagery was used for mapathons and community mapping done in OSM. This talk is about sharing my experience as a drone pilot here in the Philippines and what contributions in OSM it can do if given more opportunity in the future to fly drones in remote areas in the Philippines. Only 8% of certified drone pilots in the Philippines are women. It’s been my advocacy to encourage women to be drone pilots. In Batad Rice Terraces, a UNESCO world heritage site, there has been a massive influx of tourists coming to visit. Using a drone, I was able to acquire high-resolution imagery in 2019 for the community. The research team was able to use the image to detect tangible changes in the rice fields and houses are no longer built traditionally (from coconut trees and lumber to cement and galvanized iron sheets). The image, DTM, and DSM were uploaded in Open Aerial Map and been used in OSM as a base map to map out the recent community. Other OSM PH drone imagery collection initiatives area in urban areas such as Lupang Arenda in Taytay, Rizal, and Downtown, Dumaguete. The images acquired from these areas were uploaded as well in OAM and used as base maps in the local community efforts to map out their city and small mapathons conducted in Manila. about this event: https://pretalx.com/sotm2020/talk/8JQ7PY/
