Since OSM Ireland started their buildings project utilizing the TaskManager, I have discovered over 120 potential archaeological sites previously unrecorded by the Archaeological Survey of Ireland. In this talk, I will speak about how to identify them and the challenges and rewards in reporting them to the National Monuments Service.

In this talk we introduce ohsomeDB - the successor of the OpenStreetMap History Database (OSHDB). ohsomeDB is a scalable distributed Postgres database. It’s powered through PostGIS and Citus and a database schema optimized for OSM data analysis.

How is OpenStreetMap and it's community doing across Europe? What are the strengths of each local chapter and what is challenging or surprising them? Gregory will ask questions of a few representatives from different countries.

"Clearance" tracks OSM changes and replicates extracts under quality constraints, and its subprojects: OSM Logical History which displays changes at semantic level and UnderpassAPI, which responds to Overpass queries from the partially replicated data.

What is the current state of mapping in Scotland, we will start with some stats and counts of where things are in. terms of current statistics and the kind of mapoping that is taking place, some interesting things mapped in Scotland and some interesting stories of things mapped in Scotland.

Using Soundscape as an example, how we can use OpenStreetMap data for audio only exploration and navigation.

It's been another busy year for the development team working on the OpenStreetMap Website. We'll cover some changes you can see, some changes you might have missed, and some behind-the-scenes work laying the foundations for the future.

We'll demonstrate how Mapbox is advancing its 3D basemap by moving beyond simple building extrusions. This talk will show how we use a Python-based geospatial computer vision tool to classify roof shapes and apply a logic to style building facades, creating more realistic and immersive maps.

An update how I have been mapping the visible, and not so visible, aspects of hydro-electric power schemes in Scotland. This covers both modern schemes recently constructed, plus older schemes built over the past century. You will also learn which river now flows into the North Sea and Atlantic…

A light-hearted behind-the-scenes look running the OpenStreetMap infrastructure. From fighting bots and scrapers to rescuing failing servers, discover how the Ops Team keeps OSM.org running smoothly.

The Panoramax project started almost 3 years ago.
This session will describe the current status of the project and what we expect for the future, at the code stack level, at the instances level, as well as its governance thru a "Panoramax Foundation".

The mappers in Germany are busy as ever mapping every trail in the forest, every train signal, and the occasional collapsed bridge. But there is more going on.

With two styles for mapping sidewalks, it's difficult to map footways and use the data. This talk dives into several new tools for assessing sidewalk coverage, creating personalized and more detailed walkability isochrones, figuring out where to prioritize a new crossing, and routing based on user-defined "interesting streets".

OSM can sometimes feel like Europe vs. North America. This talk will discuss the intricacies of OSM in the US, and how and why it differs from OSM in European countries. It was also go over recent US mapping initiatives such as trails stewardship and pedestrian accessibility.

MapSwipe is an application that enables crowdsourced data collection for OpenStreetMap and helps prioritize mapping efforts by identifying areas needing updates. This talk will explore future possibilities for expanding its role, including potentially allowing direct edits to OSM and strengthening ties with the OSM community for more seamless contributions.

What are the lessons of an epically stupid quest to get every house in Brighton & Hove mapped? Can community be rekindled? Is enthusiasm dead? Who has the biggest extension in the city?

Mapping damage on OSM is critical to support the work of humanitarian organizations. Nonetheless, as recent discussions demonstrate, there is not yet a consensus on the best approach. Let's continue this conversation!

With the Nominatim geocoder we've been struggling for years to make sense of boundary and place data in the UK. In this session I want to start a discussion with the UK mappers about the current state of the data, and how it can be improved.

OpenStreetMap is a powerful foundation for outdoor navigation. Using examples from Mapy.com, specialized in hiking and cycling maps. This session explores outdoor data quality, tagging practices, and gaps across Europe. Learn how OSM supports outdoor enthusiasts today, and where the community can contribute to improve tomorrow’s adventures.

fAIr is an open AI-assisted mapping service by HOT, supporting faster and more accurate humanitarian mapping using computer vision. This talk covers 2024–2025 progress, UI/UX improvements and the role of OSM in training and output. We’ll also discuss challenges, and future plans for contributing to OSM.

The annual general meeting of OpenStreetMap UK CIC will be taking place. https://osmuk.org/
Please note: This is for OSM UK members but the board may allow others to attend as 'guests'.

This room and time has been reserved for the shortbread steering committee to meet as several of them will be attending the conference. They may be open for others from the conference to be present.

The synergy between mapping and the use of data lies at the heart of OpenStreetMap but relations have not always been as good as they ought to be. This talk examines how communication between mappers and data consumers can be improved.

We analysed 30 official cycling infrastructure datasets across the EU, standardised them, and compared them with OSM data. Missing segments were extracted automatically and then saved as geospatial files per area of analysis. These files will be shared with the community. The work is ongoing, more datasets to be added.

This talk unveils a youth-led, women-powered mapping movement from Nepal, where WhatsApp becomes a classroom and OpenStreetMap a canvas. Led by women in geospatial, we chart climate resilience through innovation and storytelling bridging continents with cartography that empowers, educates and proves mapping can be scientific and soulful.

This talk looks into the complexity of hiking and cycling routes and the new functions of waymarkedtrails.org to show complex route relations. It gives you (slightly opinionated) hints on what to tag and how waymarkedtrails.org can help when creating and maintaining route relations in OpenStreetMap.

Public transport mapping is a delicate issue in OSM. PTSA visualizes all data related to public transport stops, provides hints on tagging mistakes, and automatically groups platforms, poles and stop positions to stops. See https://gauss.whz.de/ptsa.

A look at what goes on behind the scenes to power my UK "Survey Me" tool, with advice for anyone looking to run similar tools elsewhere. Sources the tool compares with OSM include AllThePlaces and datasets for schools, healthcare, defibrillators and postboxes.

5 slots for quick 5-minute talks. Sign-up will be during the conference, making it great for fresh ideas or project updates.

fAIr is an open AI-assisted mapping tool developed by HOT, the Humanitarian OpenStreetMap Team. Recently a new machine learning algorithm was added and OSM users can experiment with mapping buildings around the globe. How well does fAIr work and has the new addition improved this?

We take an intuition about a local school crossing and, using OSM, find data to make this feeling precise through a careful analysis, and use this analysis to advocate for local change. We hope this serves as a blueprint for other people to do the similar work in their communities.

The new OpenStreetMap vector tile service powers the Shortbread maps on the home page, but you can use it too. Learn how to make your own website or style using these tiles, and better ways to customize your style.

OpenStreetMap is now well known for providing reliable power grids data worldwide. It has been achieved with yet more elaborated tooling and strategies to survey the appropriate data on ground. MapYourGrid initiative proposes to train and try on some simple practices to make grids more detailed on the map.

This session examines mapping and tagging of coastal landforms in OpenStreetMap for humanitarian purposes and community resilience building. Using case studies of common topologies in Canada and Europe, we will surface shared challenges and collectively shape solutions, workflows, and documentation to strengthen future practice.

I rode my bike from London to Berlin, and had a burning question that I wanted to answer. How many rivers did I cross? With a little bit of geospatial knowledge and some great open data, I found my answer. This is the story of why and how!

In this workshop we will generate base map tiles from OSM data using Planetiler, set up Martin tile server, set up nginx to serve our sample web site that will use MapLibre GL JS to show the map.

OpenWasteMap (https://openwastemap.uk) is a civic project mapping Household Waste Recycling Centres across the UK using OpenStreetMap. This talk explores how we built a tool from fragmented council data, using open mapping infrastructure and collaborative standards to make waste disposal data more accessible, consistent, and useful to the public.

AI content in OSM has surged over the past decade, prompting mixed reactions from contributors. We analyzed community discussions to understand emotional concerns and the shifting role of mappers. We then explored whether machine-generated roads can be reliably identified in OSM after they’ve been integrated into the database.

How we filter, merge, stabilize & improve OSM & official data at the Belgian National Crisis Centre as part of the common operational picture of police, health workers, fire brigade during times of crisis

With MapTCHA we explore if the validation of computationally generated predictions of map features could serve as an image based CAPTCHA to map new OSM objects. Following an earlier proof-of-concept at FOSDEM 2025, here we provide a development update.

The OSMF's new vector tile service updates every minute. This talk takes a deep dive into how we accomplish this, focusing on the software behind the scenes.
