OpenStreetMap is a community project to map the world. Everybody can contribute whatever they want. Or can they? What are the rules that govern what can be mapped in OSM and how? How are we creating a coherent global map and not just a bunch of random data about the world? OpenStreetMap is a community project to map the world. Everybody can contribute whatever they want. Or can they? What are the rules that govern what can be mapped in OSM and how? How are we creating a coherent global map and not just a bunch of random data about the world? For years we have had the "on the ground rule" (really more of a guideline) that helps us decide what and how to map. It has served us well, but it is also sometimes misunderstood. And it is not the whole story. In this talk we want to explore this rule and its many aspects and the other principles anchoring the project in the real world. We want to show how the rule helps avoiding conflicts but also shine a light on where it is sometimes bent and why. We want to figure out what it is that keeps the international and diverse OpenStreetMap community working towards a common goal.

In recent years, data creation methods have evolved, incorporating machine learning, AI, deep learning, and virtual reality to streamline processes. However, these advancements have not uniformly benefited communities in developing countries. Nonetheless, OMDTZ tirelessly seeks solutions to ensure more high-quality data are gathered, with low cost and extensive local involvement. One standout initiative involves a customized tricycle, known as bajaj, which is cost-effective, enabling access to streets of varying conditions. Equipped with an affordable street view camera, it collects images used to automate generation of vector data attributes to enrich OpenStreetMap. This session aims to share the experience and process, inspiring other communities to consider similar adaptations. Over the years, OMDTZ and other volunteers have spearheaded a number of initiatives aimed at updating OpenStreetMap through various projects and mapathons in Tanzania. These efforts have added countless buildings, roads, and amenities, impacting social well-being and lifesaving initiatives. As technology has advanced, methods for data creation and updating have evolved, leveraging machine learning, AI, deep learning, and virtual reality to streamline processes. In line with these advancements, OMDTZ has invested in methods to ensure efficient and high-quality data capture. One such method involves using Mapillary to capture street view imagery, which is then utilized to automate the generation of vector data and attributes such as road surface, traffic signs, and drainage coverage. Additionally, OMDTZ has customized Bajaj, equipping it with navigation and a GoPro Max camera for data collection. This approach offers cost-effectiveness compared to traditional vehicles, increased mobility in intricate urban areas, and fosters community involvement by leveraging local knowledge. Combining these technologies with local resources revolutionizes street-level data collection, contributing to the continuous improvement of OpenStreetMap in Dar es Salaam Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ about this event: https://2024.stateofthemap.org/sessions/J9ATMQ/

This proposal outlines my journey into the tech sector via OpenStreetMap (OSM) as a woman with no prior tech background. I'll share my transformation from beginner mapper to proficient user, skilled in OSM mapping and QGIS for data analysis.In a field where women's representation is limited, my involvement in OSM Tech stands as a testament to breaking barriers and fostering inclusivity—an opportunity provided to me by OpenMap Development Tanzania (OMDTZ). I’ll show the significance of providing equal opportunities and a supportive environment for women in technology in OSM and highlight the potential of OSM as a catalyst for personal and professional advancement. I aim to share, reflecting on the supportive environment that facilitated my growth while arguing for the importance of creating an inclusive space in OSM communities where women and other underrepresented groups can aspire to achieve anything.With less than a year in OSM Tech, I am already actively participating in organizational projects, including the solid waste management baseline survey—an area I am interested in as an environmental personnel. I will also share what has worked best for me and how I overcame challenges so that other women out there who want to take on the challenge can feel empowered and able to take the first steps Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ about this event: https://2024.stateofthemap.org/sessions/A7DUFU/

Over the years, iD has become a quite capable, versatile and reliable editor for OSM. However, it is currently also facing of a number of challenges: For example, it needs to keep being able to cope with the growing amount and richness of OSM’s map data, as well as to afford the increasingly important task of keeping the map up to date. This talk outlines a proposal to transform iD’s current user interface centered around OSM’s data model into an adaptive user experience that is better tailored towards the needs of individual mappers and outlines an approach of how we can get there as a community. In the past, iD had to and has overcome several challenging hurdles to become what it is today: A quite unique map editor that is the point of entry of most contributors of OpenStreetMap into the world of mapping. Today, iD is facing of a number of signifiant challenges to make it even more usable to a wide user base, and will continue to do so into the foreseeable future especially in regards to make it fit for the mapping topics of the future. For example, the editor needs to be able to cope with the growing amount and richness of OSM’s map data as well as as the increasingly important task of keeping the map up to date. The design of iD’s current user interface is substantially based on OSM’s data model. This can be seen for example in the workflow of creating a new map feature: It starts out with a blank “dummy” map geometry which – in a second step – has to be converted into a map feature by choosing a preset. While this is true to the way OSM represents this information in the data (i.e. in the form of nodes, ways and relations which are enriched with tags), this is for most simple use cases an unnecessary complication. Instead of primarily catering to the needs and requirements arising from the underlying data structures, iD’s usability should be instead built around the needs of of the different groups of mappers. And as these vary quite significantly depending on the interests and/or experience of the individual mappers, a promising approach to bring all of these together is to evolve iD’s user interface into an adaptive mapping experience with the goal to make vital mapping workflows intuitive, easy, fast and delightful. This transformation will definitely not be a small endeavor and is far from finally defined: in fact this should only be a start of a larger discussion. Let us together flesh out the details of this project.

The more detailed our mapping of the real world becomes, the more it becomes apparent that a single node, way or relation is insufficient to represent the complex properties of a real-word object. Streets have many lanes. Buildings have entrances, 3D shapes and POIs inside. And let's not even start talking about the complexity of a major railway station. This talk will take a systematic look at the different ways how complex objects are being mapped in OSM. We explore how editors cope with the complexities of detailed mapping and discuss the implication on how our processing tools need to change to better handle relationships between objects. In the early OSM days, when the map was still largely a white canvas, it was very easy to stick to a simple one-to-one relationship between real-world features and OSM objects. A street is a way. A building is a single closed way. But the more we get into the details of mapping, the more this one-to-one principle gets us into trouble. Streets have many lanes. Buildings have entrances, 3D shapes and POIs inside. And let's not even start talking about the complexity of a major railway station. For some of these complex constructs we have developed mapping schemas - using special tagging, relations or relying on spatial properties. But more often than not, the question of relationship between OSM object is sidestepped. The situation is more dire on the side of the processing tools. Most generic tools still look at every OSM object as an isolated feature. The tools that do process complex objects often do so only for a very specific type like 3D buildings or turning restrictions. This talk will take a systematic look at the different ways how complex objects are being mapped in OSM. We explore how editors cope with the complexities of detailed mapping and discuss the implication on how our processing tools need to change to better handle relationships between objects.

In this presentation, we will share our experience conducting an OpenStreetMap training program with the Kibera Girls' Soccer Academy in Kenya. We will cover various aspects such as the planning process, development of curriculum, hands-on mapping activities, and achieved outcomes. Our aim is to provide practical insights that attendees can use to run similar programs in other schools or regions, promoting greater OpenStreetMap engagement among youth. In 2022, Map Kibera collaborated with YouthMappers to launch and manage a technical training program for an all-girls secondary school in Kenya. The training program primarily focused on OpenStreetMap (OSM) but also included sessions on career guidance and digital wellbeing to introduce the students to STEM. In this session, we aim to share the resources that were used to model how OSM communities and organizations can join forces with secondary schools to conduct impactful training programs. We will also emphasize the significance of OpenStreetMap in developing technical skills and advocating for STEM education in young learners. Additionally, we will include how such programs promote inclusivity and the strategies to make training programs accessible and encouraging, especially for girls in marginalized communities. The attendees will gain a better understanding of the steps involved in planning an OpenStreetMap training program for high school students and acquire insights into customizing mapping activities to cater to a younger audience.

Better information leads to better city policy. Unfortunately, many of the world’s cities still lack basic information on their own transport systems, leading to decisions measured against anecdotes rather than data. Using new tools for data processing and display, OpenStreetMap can provide the information that governments need to make better decisions. In this panel we will share recent success stories of cities adopting OSM-based metrics to plan better transport. We will reveal new tools that governments, mappers, and advocates can use. And we will discuss the challenges that still remain and the roles the OSM community can play in overcoming them. Transport is among the largest sources of greenhouse gas emissions, and transport emissions are growing especially quickly in the Global South. Experts agree that vehicle electrification will not be sufficient to avoid climate catastrophe: we also need to redesign cities to make it easy for people to walk, bicycle, or ride public transport instead of driving. OpenStreetMap can help. OpenStreetMap can empower cities to make planning decisions based on real data, and to set more meaningful goals for progress. OSM has empowered cities like Fortaleza and Recife, Brazil, to plan expansions of their bicycle lane networks that serve the greatest number of potential cyclists. OSM has helped cities as distant as Seattle, USA; Jakarta, Indonesia; and Pimpri-Chinchwad, India, to optimize their public transport networks and make it easier for everyone to ride the bus. And this is only the beginning. New tools are proliferating, such as ITDP’s Atlas of Sustainable City Transport and Trufi’s GTFS-Builder. These tools make it much easier to turn OSM data into useful indicators that can guide city policy. In the case of Trufi’s work, it does so by converting OSM data into industry-standard formats that can be used for trip planning or network analysis, As tagging evolves, OpenStreetMap is emerging as a solid foundation for creating multimodal route planning networks, thanks to its comprehensive information for generating integral maps. Furthermore, Trufi has developed a specific course on mapping public transportation routes, with the objective of training the OpenStreetMap community to contribute effectively to this particular aspect within the platform. ITDP’s Atlas, on the other hand, uses OSM as well as other open sources to present measurements of meaningful indicators that city governments can use to set goals or compare themselves to nearby jurisdictions. Some challenges, however, remain. It can be difficult to explain the virtues of OSM to governments who have never used it before. The tagging schema does not include certain nuances that are important for bicycle infrastructure planners (although a current proposal remedies many issues). And, looking more broadly into the future, there are many promising opportunities for the OSM community to push into new frontiers of data on topics like road usage, footpath quality, and parking. In order to prevent catastrophic climate change, we need to change the way people move around cities. In order to do that, we need maps.

OpenStreetMap (OSM) is a collaborative mapping platform with provides open and easy access to its users. It has diverse usability including the general public to governmental and non-governmental organizations. This abstract presents the usage of OSM in general and in the context of Nepal. OSM is used by the local community, the government sector and NGOs, tourism, classrooms, and various projects contributing to the development and gender equality making it a versatile data source. OSM gives a sense of empowerment and responsibility to individuals and contributes to fostering resilience and sustainable development. OpenStreetMap (OSM) is a free and open-source mapping platform where individuals collaboratively create, edit, use, and share geospatial data. OSM is used by a variety of users and stakeholders for their respective purposes. For the general public OSM is used for navigation because of its user-friendly nature. Mobile applications like MAPS.ME and OsmAnd provide offline access to maps. Additionally, it facilitates community engagement bringing a sense of empowerment and responsibility among individuals. Government sectors and NGOs use OSM data for planning developmental activities. The OSM data is extensively used in humanitarian response, Nepal is prone to disasters like earthquakes, landslides, and floods OSM has played a crucial role in allowing volunteers to respond quickly with the most updated maps with local information. OSM also plays an important role in tourism; guides, hikers, trekkers, and mountaineers use tourist maps prepared using OSM data as it provides detailed maps of hiking trails, mountain peaks, and natural landmarks. Gender equality is also an important domain that OSM has impacted upon, its various projects of mapping women-centric points of interest, addressing the issue of female genital mutilation, She Leads She Inspires programs, and empowering women as contributing to it remotely itself is the task that most females prefer to do. The students in the classrooms use OSM data for their projects and research. OSM data is preferred in the analysis as it is up-to-date and contains detailed information. Different student clubs like the Geomatics Engineering Society (GES), a registered OSM community in Nepal conduct training, workshops, and mapathons contributing to capacity building. Overall, OpenStreetMap offers a spectrum of usability to individuals, volunteers, companies, and organizations and stakeholders ranging from navigation to disaster response and empowerment of individuals and community as a whole.

Rosenpass is a post-quantum secure cryptographic protocol, an implementation of that protocol in the Rust programming language, and a governance organization stewarding development of both protocol and implementation. When used with WireGuard, Rosenpass functions as a ready-to-use virtual private network with full security against quantum attackers.The development of a technology like Rosenpass is complex and requires a good footing in cryptographic research, software engineering, industry practices, and science communication. Bringing together these diverse threads of activity is an ongoing challenge. Individual work is not enough, it takes a group; an organization. We are the group that tries to tackle these challenges for Rosenpass.In this talk, we will focus on Rosenpass as a protocol and explain the principles used and challenges encountered when designing such a protocol. Equipped with ample time and many scientific illustrations, we hope to give insight to an audience with many different levels of knowledge about cryptographic subjects.This is not a lecture for experts. This is supposed to be entertainment for the technologically inclined.In the talk we are going to explain what key encapsulation methods are, how they are different from "non-interactive key exchanges" – often just called "Diffie-Hellman" operations. We will demonstrate how key encapsulation methods can be used to build a secure cryptographic key exchange protocol and how the X-Wing fighter can be used to provide cryptographic redundancy.Finally, we will turn our attention to attacks we found against WireGuard, show off a protocol level denial-of-service attack against WireGuard and explain how we solved that attack in Rosenpass. about this event: https://sessions.hack-mas.at/event/jzGHNoejBMT5hNBbC/how-to-build-post-quantum-cryptographic-protocols-and-why-wall-clocks-are-not-to
