The code samples, status, recent development and roadmap of the open-source community driven project for rendering of (not only) OpenStreetMap vector tiles in a web browser (GL JS) and with native code (Android, iOS, etc). After Mapbox announced the closure of Mapbox GL JS, their JavaScript library for displaying maps using WebGL, the community around Hacker News gathered on Slack and GitHub and m...

Since moving to Ireland from Germany in December 2016, I have been mapping heritage features on the island increasingly. During lockdown, I started a YouTube channel to enable other people who are interested in Irish history to learn about OpenStreetmap, because it is still quite unknown in those circles. After moving to Ireland and shortly after becoming a member of a local historical society, I...

The osm2pgsql has been around for a long time. Since 2006 it is used to import OSM data into PostgreSQL/PostGIS databases for rendering and other uses. In the last years there have been a lot of improvements to osm2pgsql. With the new "Flex" output, osm2pgsql is now much more versatile which allows new applications. The osm2pgsql has been around for a long time. Since 2006 it is used to import OSM...

A deep dive into how StreetComplete stores edits and syncs them with OpenStreetMap, including persistence, solving conflicts and allowing users to revert their edits. StreetComplete is known as an app to easily contribute selected data to OSM on the go. The simple interface could make it appear that the technical implementation is equally simple. It is maybe a common misconception that things that...

Turkish OpenStreetMap Community has constantly been growing with members from various circles in recent years however the community faces various problems such as insufficient OSM documentation and tools in Turkey and lack of learning materials in Turkish. Yercizenler and Youth Season NGOs kicked-off the Open Source Volunteering Programme to tackle community needs to build and enlarge OpenStreetMa...

We have developed an open source web app, OLMap, to take photos of entrances and map them in OSM and another one, Gatesolve, for delivery drivers to find the route to the right entrance based on this micromapped OSM data. Last year, over 6000 images including 5762 entrances, 1767 flights of steps, 645 barriers and 241 info boards were contributed to the 30000 entrances mapped in Helsinki, Finland....

The mapping of access restrictions is often neglected, but access restrictions (and default assumptions about whether a path without any such information is usable or not) are important to make OSM safe to use. OpenStreetMap has grown from a geeky niche project to a respectable data source powering a multitude of apps and web sites. Our ethos is to “map reality”, and our approach is incremental –...

How to remotely map a city's public transport when due to the pandemic local trainings and community buildings are not possible. Financed by the World Bank who wants to support the infrastructure of Mauritania and also the planning of the bus system, we from Trufi Association wanted to map the public transport of its capital Nouakchott. Our typical approach would be to train and empower local comm...

Improving OSM data quality and coastal community resilience with the Map Quality Measurement workflow. Over the past few years, the world has been experiencing the impacts of climate change with an increase in extreme weather events. Coastal communities are among the most vulnerable and face a range of unique flooding hazards including storm surge, wave impact, and erosion causing damage to homes,...

Over the past year, the Mapbox Data RAVE team has worked to improve data quality issues and engaged with various communities according to the Organized Editing Guidelines. The experience has been great and varied significantly from place to place. This talk will share the details and learnings for the community and other editing teams. In October 2020, as part of on-going work to improve the quali...

Makina Maps is a new stack to produce vectors tiles on request from updated OSM database. The same thing we except from Mapnik, osm2pgsq and mod_tile stack, but for vector tiles. The Vector Tile is a mapping solution where the Data Vector Tiles are served separately from the style and only assembled eg. in the web browser. Makina Maps is new Vector Tile Server build using Docker and based on Impos...

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 MapContr...

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...

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...

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...

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 populati...

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 sit...

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...

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...

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 Menschenrechtskonventio...
