Processing such large datasets as OSM is a tricky business. In this talk I would love to tell a story about a set of optimisations and tricks that allowed to reduce graph building time for Valhalla routing engine in 3 times. It's a story about C++, OSM and geospatial data and how obvious things can lie unnoticed without a proper tooling - or how to measure performance on such scale and find what to fix.

The availability of road network data at scale in OSM has fueled a solid ecosystem of open-source projects dedicated to route planning: OSRM, Openrouteservice, Valhalla, GraphHopper, Jsprit, Vroom to just name a few.

As the Executive Director and Program Coordinator at OpenStreetMap US, Maggie and Alyssa are lucky to say OpenStreetMap is their full-time job. OpenStreetMap US is both a local chapter of the OpenStreetMap Foundation, and an independent 501(c)(3) nonprofit organization in the United States. This presentation will explore how OpenStreetMap US has evolved the organization’s approach to community building, as communities of mappers emerge and dissolve across the United States.

A few topics that will be covered in this talk include:

Whether you are a leader of another OSMF Local Chapter or the only mapper in a 100 mile (sorry - kilometer) radius, you’re invited to explore what it means to build a mapping community with us.

Over the past year, several Dutch governmental organizations collaborated to initiate Panorama, a new open street‑level imagery effort. This talk explains how the project was set up, how data collection and processing were organized, and how the resulting imagery strengthens public digital autonomy. Similar to developments in France—where IGN has taken a leading role in producing sovereign geospatial data—Panorama aims to reduce dependency on commercial suppliers and ensure long‑term control over essential imagery.

This talk will introduce Ultra, an alternative high-performance front-end to overpass, qlever, sophox, and more powered by MapLibre GL JS. It will cover the basics of how Ultra works: choosing a backend query service and authoring your query as well as how to style the query results using MapLibre.

OpenStreetMap is one of the most powerful open geospatial datasets in the world, yet for many who stand to benefit most from it, it remains invisible. NGO workers planning humanitarian responses, students conducting research, local planners building community infrastructure, and developers looking to build location-aware applications often don't know where to start, which tools to use, or how OSM can realistically achieve their goals for their work.

UseOSM is a community-driven platform built to close that gap. It brings together tools, real-world use cases, and community stories in one accessible place, presented in plain language that anyone can understand, not just experienced mappers.

This talk will walk through the full vision and current state of UseOSM, covering:

Why UseOSM exists — the visibility and discovery gap that motivated the platform, and why making OSM's impact legible to the wider world matters for data quality and community growth alike.

How anyone can get value from it — whether you're an NGO seeking the right tools for field data collection, a researcher looking for project inspiration, or a developer hunting for OSM-powered software to build on or learn from.

How to contribute content: a walkthrough of the contribution guidelines for adding use cases, project spotlights, statistics, and stories that reflect the true breadth of what OSM data powers.

How developers can contribute — a clear onboarding path for technical contributors who want to help build and improve the platform itself.

What comes next — the repository maintenance workflow, governance model, and a preview of upcoming features on the platform roadmap.

The core argument is simple: the more people understand what OpenStreetMap makes possible, the more motivated they become to use and to contribute well. Every navigation app, every humanitarian response tool, every urban planning dataset quietly powered by OSM is a missed opportunity to inspire a new contributor or spark a new creative project. UseOSM turns those quiet successes into visible, shareable stories.
