The [OpenStreetMap community awards](https://blog.openstreetmap.org/2025/06/07/call-for-nominees-openstreetmap-awards-2025-in-manila/) are nominated and chosen by the community. The OpenStreetMap awards is a global recognition event that celebrates contributors from all corners of the OSM project – including mappers, developers, community organizers, writers, and everyone who makes OSM great. This...

During the OpenStreetMap Foundation Board Ask Us Anything (i.e. AMA) session, we will take questions from the audience oand/or more questions that the larger community can submit before the event. We can discuss the board's past actions and our future plans. Let’s have a conversation about the Foundation and the Board and how all the parts work together. If you know nothing about what the board is...

Access to safe water and sanitation is critical for public health and sustainable urban development, yet significant disparities persist in informal settlements across low- and middle-income countries. This study explores inequalities in WASH access within Korogocho and Viwandani which are two densely populated informal settlements in Nairobi, using a participatory geospatial approach. Community m...

What could you really accomplish with 100 days of consistent mapping? Add 1000 buildings, delete 100 nodes, or achieve completeness for an entire neighbourhood? Within the OpenStreetMap community, mappers contribute at different levels and frequencies using several tools and editors to enhance the map. In this presentation, we will share our experiences mapping every single day - the lessons learn...

In this talk I will describe the pros and cons of using the pmtiles vector tile format in comparison with other tile formats. I will then talk about some of the tools available to generate pmtiles tiles based on OSM data and other GIS formats, inspect these tiles and visualize them on a website. Finally, I will demonstrate how I built in the real world a data pipeline to filter and transform OSM d...

Unlike most world maps, OpenStreetMap is built by a global community with a keen focus on local knowledge. For many local communities, proper representation of the native language is just as important as getting the locations right. OpenHistoricalMap extends this approach back in time, incidentally tracking the evolution of written language through toponyms. Increasingly, users experience both pro...

The Open Mapping Gurus are more than skilled mappers—they are changemakers rooted in their local contexts, driven by purpose, and committed to building resilient communities through open data. As mapping needs shift from short-term project engagement to long-term sustainability and impact, we need to equip these local champions not just with tools—but with vision, leadership, and strategy. This wo...

On December 14, 2024, the territory of Mayotte, a French department of more than 300,000 inhabitants made up of several islands between Africa and Madagascar, was hit by the passage of Chido, the most violent cyclone it had seen in more than fifty years. Pleiades imagery taken in the following days, between December 17 and 24, were posted online and released for the OSM contribution. These images...

The UN Maps Programme, an initiative from the Department of Operational Support at the United Nations, provides topographic maps, operational geo-information, search and navigation tools, and imagery and street-level base maps to peacekeeping and humanitarian actors in UN mission areas. UN Maps has established a community of OpenStreetMap (OSM) data contributors called UN Mappers. The UN Mappers c...

During disasters, there is a need for accurate, rapid, and reliable mapping, validation, and damage assessment to inform humanitarian response and recovery efforts. However, as disasters are often extensive in scale, it is important that these methodologies are scalable and can be employed for multiple affected areas at any point in time. Crowdsourced mapping, validation, and damage assessment, wh...

Rare in Asia, house numbering grids are indeed present in the Philippines, as an analysis of OpenStreetMap data shows. In places like Bonifacio Global City the names of roads themselves form a quite advanced pattern, with non-overlapping street vs. avenue numbering. House numbers are absent. Other places like Pasay have odd numbered street names perpendicular to even. If the physical streets form...

This talk will present the OSM Swiss Style project and the new OSM Swiss Base Map, which was developed by University of Applied Sciences OST, in cooperation with ETH Zurich, Sourcepole AG and the Swiss OpenStreetMap Association. The goal is to create a base map for thematic maps that blends Swiss cartographic design principles such as clarity and readability with modern technologies like vector ti...

OpenStreetMap has celebrated its 20th birthday last year. Over the past two decades the community grew tremendously and now covers (almost) the entire globe. This talk summarizes OSM’s evolution with maps and meaningful numbers. We want to take a look at the “state of the map”, current mapping trends and some of the challenges that we face. We look at the size of the active community, analyse regi...

This talks presents the "Postpass" service, a database that services OSM data for public querying much like Overpass, but uses PostGIS under the hood. With a few extra characters added to your query, you can have the power of PostGIS at your fingertips from within Overpass Turbo. Overpass and Overpass Turbo are indispensable tools for OSM contributors - everyone uses them whenever you need to glan...

Building a strong and inclusive mapping community requires leadership, collaboration and a vision that aligns with global geospatial initiatives. As an Om Guru Advanced Mapper, Kathmandu University YouthMappers President and Executive Member & Sole Mapping Lead of Geomatics Engineering Society (GES) for tenure 2025, I have worked extensively to expand Nepal’s OpenStreetMap (OSM) ecosystem, integra...

Whether you’re a simple mapper or a sophisticated data consumer, you depend on a lot of machinery at the heart of OpenStreetMap that you probably never think about. After many years mapping and tinkering on OSM-based frontend applications, Minh is venturing into the software core of OSM’s world. Join him as he recounts his travels, unearthing the many moving parts beneath the surface and piecing t...

The open mapping movement in Sri Lanka has gained significant traction in recent years, with grassroots organizations demonstrating how open geospatial technologies can serve as tools for advocacy, resilience, and participatory governance. Supported by the Vriddhi Project, implemented by UNOPS Sri Lanka, this initiative introduced OpenStreetMap (OSM) and complementary open-source geospatial tools...

World-Map-Explorer is a web application that helps the visually impaired learn about the world and understand maps. It is a great pleasure to note that the application was developed by a group of students from the Computer Science Department of Sri Krishnapuram Government Engineering College in collaboration with Zendalona with support of OpenStreetMap Kerala Community. This app, which can be used...
