MapComplete is a newly created, easy-to-use web editor. In this talk, the developer will talk about the editor, how it came to be, how it already performed and what could possible come - especially with your help. MapComplete is a newly created web editor which aims to be really easy to use. It tries to be just as simple as StreetComplete while offering per-topic views and presets just as MapContrib. In this talk, I present the editor I've made. I will talk about the editor itself, how it grew in the past year and a half, some technical background and give some statistics on edits made with it and which themes proved to be interesting. I'll also touch upon the possibility to create your own theme (but I'll do an Q&A-session specifically for that). Furhtermore, a comparison with other editors in the OSM-ecosystem will be made and differences with StreetComplete and MapContrib will be highlighted, as those two editors were key in inspiring this editor - yet there are some important differences with MapComplete in it's goals resulting in a fundamentally different approach and different use cases. I'll also zoom in on how the user journey is and how a few small features become available when the time is right for them to appear. Finally, I will have a look to where MapComplete could be headed and which projects and technical innovations will be made in the future. If you already want to try the editor, give it a shot at mapcomplete.osm.be about this event: https://2021.stateofthemap.org/sessions/3E98CC/

Nominatim, the well-know OSM search engine, has recently received a major update of the algorithm that computes addresses from the boundaries and places in OSM. This talk first introduces the new algorithm, explains the background and how it translates to tagging. We'll then take a step back and explore the larger picture what the evolution of tagging scheme of OpenStreetMap means for the users of the data. Nominatim is the search engine that powers the search box on the main OSM site. One of the fundamental steps of preparing OSM data for searching is the extraction of information about their location, commonly known as their address. This is not a simple task because OSM data is much less structured than traditional databases and many users revert to using external data for this reason. However, the data is there and should therefore be usable. In the course of the last year the address algorithm of Nominatim received a major overhaul to improve how addresses are generated from OpenStreetMap data. The first part of the talk introduces the new algorithm and how it came to be. We'll look into the current state of tagging of boundaries, the problem of the urban/rural divide and the difficulties of country-specific mapping. The second part of the talk deals with the more general question what the evolving tagging schema of the OpenStreetMap database means for data users. The free-form tagging is one of the big strengths of OpenStreetMap. But the lack of rules does not necessarily have to mean lack of order. Using the example of address extraction, I'd like to discuss the future of the tagging schema from the point of view of a data user. about this event: https://2021.stateofthemap.org/sessions/QUHKNR/

OSM publishes with its geodata also meta data describing the contribution process and contributor. This talk gives an overview of the actual privacy prospects for OSM consumers, potential privacy risks for OSM contributors, and attempts a preliminary compliance check with respect to the EU’s general data protection regulation (GDPR). I am a professional data protection expert and a passionate long-term contributor to OSM. For this talk, I want to combine both worlds and discuss: * 0) How OSM already today is beneficial for the privacy of OSM consumers? * 1) Which personal data is in the OSM public database (spoiler: behavioural data of contributors)? * 3) Which potential privacy risks stem from the data for OSM contributors? * 4) What are the GDPR compliance issues? * 5) What is the outlook? I open the discussion (Q&A) with some ideas to mitigate privacy risks. They involve likely changes to the current data governance, OSM database structure and OSM data itself. Problems that are already evident that I plan to mention: 1. transparency on the processing of personal data of contributors 2. tracking of contributors, e.g. via - [https://resultmaps.neis-one.org/oooc](https://resultmaps.neis-one.org/oooc) - [https://overpass-turbo.eu/](https://overpass-turbo.eu/) with search "user:username" - [https://hdyc.neis-one.org/?username](https://hdyc.neis-one.org/?username) 3. sharing of OSM data with third parties, see [https://wiki.osmfoundation.org/wiki/Registered_data_controllers](https://wiki.osmfoundation.org/wiki/Registered_data_controllers) For the purpose of the discussion, I want to introduce the audience to a few core data protection concepts: - purpose limitation - data minimisation - definition of personal data in the GDPR - concept of anonymous and pseudonymous data about this event: https://2021.stateofthemap.org/sessions/RJZRZ8/

The open-source 3D renderer OSM2World turns OpenStreetMap data into detailed 3D models of the world around us. The mission of OSM2World is to build a realistic 3D representation of the physical world using open data and open-source software. This is made possible by two trends: The increasing level of detail captured by the OpenStreetMap database, and the growing availability of open technologies for high-quality 3D rendering. Creating 3D models from OpenStreetMap wouldn't be possible without the impressive effort of the mapper community. One of the goals of OSM2World is comprehensive support for the rich landscape of tagging, such as Simple 3D Buildings and Simple Indoor Tagging. Besides the outside and inside of buildings, the rendering displays lane mapping for roads as well as a large number of other OSM features – likely more than any other open-source 3D renderer. In addition to the ongoing work to support a larger share of the OSM data model, OSM2World is being updated to make good use of modern technologies, including physically based rendering (PBR), the glTF format, and WebGL. These make it easier than ever to export visually appealing 3D models for use in many modelling tools or engines, and to display them on the web. This talk introduces the capabilities of OSM2World, with a particular focus on features which were added recently. As such, the session is intended to be suitable for visitors learning about OSM2World for the first time as well as those interested in staying up-to-date about new developments. about this event: https://2021.stateofthemap.org/sessions/ZVL93H/

This talk will focus on the MapaTanda Project (a portmanteau of Mapa -- which means a map -- and Tanda -- which can mean older adult but can also mean remember) and why we need to build an age-friendly society through OSM. This is a project that seeks to improve the number and quality of data in OpenStreetMap that are important and relevant to older adults (senior citizens) and the ageing population (60+ years old). In a nutshell, MapaTanda seeks to improve both the quantity and quality of data in OpenStreetMap that is important and relevant to members of the older adult and ageing population (60 plus years old) in the Philippines. This involves adding and cleaning features in OpenStreetMap such as nursing homes, hospitals that provide specialized care for the elderly, retirement homes, local offices for senior citizen affairs, community centers and other facilities that cater to or provide perks and services to older adults, etc. These data can then be used by local and national organizations for policy-making, planning, and implementing projects and interventions. SmartCT's goal as an organization is to put citizens and data at the heart of developing smart cities and communities in the Philippines. We believe in an open, inclusive, holistic, and citizen-centric approach to building smart solutions. To do this, we partner with actors such as local government units to ensure that they have access to quality open data that they can utilize for planning their programs and services. We believe in the power of open data and consider OpenStreetMap as a great amplifier of that power. This talk will focus on community building and openness as foundations of age-friendly cities and communities. Our main goals for its talk are below: 1. Recruit new OSM volunteers 2. Engage the older adult population to contribute in OSM 3. build stronger relations with the local and global OSM community as well as foster partnerships with more local government units and national agencies. 4. call to institutionalize openness through policies about this event: https://2021.stateofthemap.org/sessions/TPKBQ9/

From remote mapping to OSM-based analytical tools for decision making, CartONG would like to share its experience on building and implementing step by step since 2017 an overall strategy to support humanitarian response in refugee sites with UNHCR. We will focus on specific technical challenges, like dealing with accurate and precise data on a large number of sites at world scale as well as at site level. CartONG is an NGO specialized in Information Management whose mission is to put data – in particular geographical data – at the service of humanitarian, development and social action projects. CartONG is one of the implementing partners for mapping and information management (IM) projects of the UNHCR, a UN agency dedicated to protect refugees, forcibly displaced communities and stateless people. Getting data on refugee sites has always been a challenge given their fast evolution and the diversity of situations around the world. Therefore CartONG has been promoting OpenStreetMap as a complementary resource and sharing platform to produce accurate and recent data that can complement UNHCR’s existing database while also benefiting other actors (in particular local ones). From remote mapping to OSM-based analytical tools for decision making, CartONG would like to share its experience on building and implementing step by step since 2017 an overall strategy to support humanitarian response in refugee sites with UNHCR. We will focus on specific technical challenges, like dealing with accurate and precise data on a large number of sites at world scale as well as at site level. The implementation is still ongoing and the strategy also evolves as it moves forward to better fit the requests of the partner as well as evolution of the OSM landscape: we will present where we stand and what is planned for the next steps. Step 1/ Improve the consistency of the refugee sites’ tagging model on OSM (wiki documentation/ mapping data model) Step 2/ Promote refugee site mapping on OSM (training/mapathons/data integration/ cooperation among actors) - Improve the availability and quality of OSM data on refugee site around the world - Facilitate contribution and use of OSM data. Step 3/ Build a dedicated OSM replica for UNHCR specific use cases Step 4/ Monitor activities on OSM camp mapping - Complement UNHCR’s database and compensate for lack of data on specific sites. Step 5/ Generate a specific map rendering Step 6/ Feed a web application for spatial analysis - Create analysis products (including maps, sector indicators visualization, etc) using OSM as well as other data sources, and make them available to UNHCR’s team and other actors for field operations about this event: https://2021.stateofthemap.org/sessions/XLDXW9/

Grab launched a navigation product for Driver partners in 2018 with the help of OSM. We contributed to OSM data in Singapore and made it navigation ready to enable launching in-app navigation for Grab's driver partners. This talk is a glimpse of the journey to get the map data quality and in turn the product experience to be the best suited one for driver partners in Singapore. Grab's journey with OSM started in 2015, with the road geometry being the one mostly used to calculate ETAs and routing. Based on this use case, we started enhancing the OSM data using GPS probe based detections and satellite imagery. After the success we saw with the ETA and routing quality that we could achieve with OSM in Singapore, we started dabbling with the idea of piloting Navigation quality maps on OSM. Our journey on this started with researching the local traffic rules, signboards and restrictions that are relevant for Navigation. As Singapore is one of the countries in SEA which is well marked with all signs in SEA, we then moved on to solve the next level of challenge which is adding street level imagery across the country with the help of different cameras we could lay our hands on for the pilots. At times we used mobile phones with KartaView app and others we managed to add using better quality Go-Pro like cameras. Few interesting learnings along the way; Rain can play a spoilsport to your plans at the last minute; Government, building authorities would need time to give you permits for collecting imagery and you will need to plan those into your collection efforts; Roadworks, Road closures, congestion do not let you cover all streets fully. Despite all the planning, sometimes you may not get permissions, Eg: Private condos. For such situations, you can work with the local community to help add more imagery. Interesting learnings while mapping Singapore: Tunnels, Underpasses, etc. criss cross on multiple levels. Oftentimes mappers get confused, despite the availability of imagery. Road name abbreviations are sometimes not standardised and will have inconsistency when showing on maps. Maps are never perfect even in a well mapped country like Singapore as the physical world around you is changing. Instead of trying to be perfect, you can aim to be very agile and responsive, making the real world changes reflect in the map data as close to realtime as you can get. What can help you in doing this well is working closely with local transport authorities (SLA, LTA, etc. in case of SG); Other major realtors and establishments which run several malls, office buildings, tech parks, etc. And last but not the least - community. Both the OSM community and our driver partner community helped us immensely here. The journey to making the map for Singapore was quite arduous and needed the continued support of OSM community mappers, driver partners, local map operations teams. Everyone constantly keeping the map updated and improved helped us make the navigation to be best suited for the needs of Grab driver partners. We engaged these communities through various activities such as Geo*Stars, mapathons with organisations such as GeoWorks and hosted in-house mapathons to enable understanding and contribute to the amazing OpenStreetMap data. For our driver partner community, we started off with a whatsapp group to gather feedback and then proceeded to an in-app collection mechanism to make this reporting of road updates, map changes, a lot faster and seamless. This coupled with our on-ground map operations teams which run road tests of the navigation helped us ensure our map stays as updated as possible. Working closely with the community ensured that they also could see the impact they were making on the maps every day. This made Grab Driver partners to like Grab Navigation even more as it empowered them to build it together with us. This journey doesn’t end here, and we will be working even more closely with the community across South East Asia as this is the best way to scale these efforts on building maps for everyone. about this event: https://2021.stateofthemap.org/sessions/D7JREJ/

The common theme for OSM editors is presenting a map for moving things around. But for attribute editing, a map is too distracting. Let's see how getting rid of it improves the editing experience. The future of OpenStreetMap editing is not another JOSM or another Potlatch. What we have is good enough, and there are options for everyone. But 15 years on, the same problems persist in OSM: while it's very easy to draw things, to add a road, a building, or an amenity, updating the map is so hard virtually nobody does that for free. That can only be fixed by tailoring editors to the task, because general-purpose editors cannot help. That is the future: thematic editors. In this talk we'll take a look at existing specialized OSM editors, like OSM Contributor, MapSwipe (I know), or StreetComplete. We will also note when an editor doesn't need a map to operate. And finally we'll imagine a few editors that could simplify maintaining the map, both on desktop and on mobile. The speaker, Ilya Zverev, has made the well-known Level0 editor which doesn't need a map to function, but also isn't strictly a thematic editor. Recently he's made a Telegram bot for a POI directory, which also featured an optimized POI editor. It enabled Ilya to collect ~500 shops and amenities in 10 days, and to keep the data recent. It didn't provide an interactive map, obviously. about this event: https://2021.stateofthemap.org/sessions/BWLNAC/

Wie immer versuchen für jeden Termin auch Vortragende aus der Region zu finden. Dieses Mal berichtet uns Max-Jacob Ost (@GNetzer) von seinem aktuellen Projekt: Max lebt in Obergiesing und produziert seit 2014 zusammen mit Frank Helmschrott den Fußballpodcast “Rasenfunk”, eine regelmäßige Gesprächsrunde über Fußball, die sich allein durch freiwillige Zahlungen der Hörerinnen und Hörer finanziert. Wer sich für die Hintergründe dazu interssiert, sei an dieser Stelle auf den Vortrag auf der Subscribe9 verwiesen. Beim Meetup geht es aber um den Podcast “11 Leben – Die Welt von Uli Hoeneß” in dem er anhand der Person Uli Hoeneß die Geschichte des deutschen Fußballs nachzeichnet. “11 Leben” ist im September 2020 in Zusammenarbeit mit Wakeword und Audionow gestartet. about this event: https://podcast-muc.de/termine/2021-07-meetup/

Eine Allianz aus NGOs und Privatpersonen hatte seit dem Jahr 2013 unter dem Slogan "Privacy not Prism" versucht, den britischen Geheimdienst GCHQ wegen Verstößen gegen Menschenrechte zu belangen, weil er in einem umfänglichen Internet-Überwachungsprogramm massenhaft Kommunikationsdaten sammelt und analysiert. Diese anlasslose Massenüberwachung ist nicht mit der Europäischen Menschenrechtskonvention vereinbar, entschied die Große Kammer des Europäischen Gerichtshofs für Menschenrechte in Straßburg im Mai 2021. Die illegalen Eingriffe in die Privatsphäre von Millionen britischen und europäischen Menschen werden durch das Urteil nun neuen Regeln unterworfen. Welche neuen Vorgaben sind das? Werden Kommunikationsinhalte und Metadaten unterschiedlich behandelt? Kann die Massenüberwachung dennoch bestehen bleiben? Welche Folgen hat das Urteil, wird die Überwachung von Kommunikationsdaten nun gebremst und die Geheimdienstkontrolle verstärkt? Welche Erkenntnisse brachten die mündlichen Anhörungen? Diese und weitere Fragen soll der Vortrag ansprechen. about this event: https://c3voc.de

Following on from the brief introduction at the LibreOffice Summit, I will re-introduce Firebird, the open source version of Interbase, the original embedded systems database. Firebird is a high performance, small footprint database with a long (and interesting) history. Firebird features Stored Procedures, Transactions, Encryption, multi user access, and is SQL-92 compliant, and can handle databases as large as _20 terabytes._ Because of its small size, efficiency multiplatorm nature, Firebird is ideally suited to IOT and edge device deployments, at any tier of system architecture. I will go through the steps required to prepare new database for production and multi-user operations, using a simple Django deployment as an example.
