Community

  • Pascal Neis recently conducted a GNSS accuracy comparison involving drones, an action camera, and a smartwatch. In the experiment, both the DJI Avata and the NEO drones successfully recorded GNSS tracks, but commonly deviated several metres from the reference route. The GoPro action camera yielded similar or slightly worse accuracy, with GNSS tracks occasionally straying even farther than the drones. In contrast, the Garmin smartwatch delivered the most consistent and accurate results.
  • Martijn van Exel published his slides and cleaned-up speaker notes from his talk about MapRoulette and his lightning talk about the Meet Your Mappers tool given at State of the Map US in Boston.
  • Graham Park provided an explanation on how to utilise Strava traces for mapping paths in OpenStreetMap, noting that contributors are permitted to use Strava heatmap data for tracing, a usage right reconfirmed in November 2019.
  • Christoph Hormann commented on the recent controversy over the OpenStreetMap Foundation’s largest externally funded project to date, warning that it risks creating conflict between those driven by substantial extrinsic motivations, such as financial incentives or vague promises of money, and a community of intrinsically motivated volunteers. He emphasised that this issue stems from the broader problem of generational turnover within the OSM project and encouraged the community to develop their own approaches to facilitate this transition, either by creating their own methods or by pressuring the OSMF to begin taking responsibility.

OpenStreetMap Foundation

  • On Wednesday 25 June at 21:43 UTC the OpenStreetMap Grafana dashboard indicated an issue with the minutely replication diffs not updating. This disruption led to several downstream problems; most notably, newly uploaded changesets could neither be queried on the map nor rendered. The issue was first reported by community member queenofthenightosphere at 23:37 UTC. The OSM services that rely on this diff stream to stay in sync with the live database, including the Overpass API, tile rendering, Nominatim, and others, stopped updating. While the changesets were safely stored, they could not be accessed through these services due to the sync failure.

    • To resolve the issue, the OpenStreetMap Operations Team temporarily took the main site offline for maintenance. This was done to bring the replication diffs back into alignment with the database. The maintenance was successfully completed around 13:27 UTC on Thursday 26 June.
    • As of 14:06 UTC, several core services, tile rendering (tile.osm.org) and Overpass API, had caught up with current OSM edits via diffs. However, Nominatim was still in the process of catching up. Other services, especially third-party instances, may take additional time to fully resynchronise. The root cause appears to stem from an unexpected issue involving PostgreSQL and how osmdbt pulls replication diffs from the database.

Events

  • State of the Map Europe, happening in the UK this November, has opened its call for proposals. Across eight tracks, they hope you will propose talks, panels, and other sessions for the schedule.

OSM research

  • HeiGIT reported that a new paper was published by Huber et al., introducing the isocalor approach to assess how solar exposure and heat stress affect pedestrian access to essential services in Heidelberg, Germany. The study used OpenStreetMap data and a customised openrouteservice routing engine, and was conducted within the framework of the HEAL project.
  • Daniel Schep, Overpass Ultra’s developer, requests your input on how users engage with Ultra.
  • Ibra Lebbe Mohamed Zahir and colleagues have assessed the impact of the Booster Grants programme on climate activism and education among YouthMappers in Sri Lanka. Funded by HOT/Open Mapping Hub Asia Pacific, the programme supported grassroots mapping initiatives. Eastern University, Sri Lanka, was among its local implementing partners.

Maps

  • Lostmonkey tooted the ’17 Walls – Murals in Aarhus, Denmark’ , a uMap that shows the geolocation of the murals from the ’17 Walls project’ plus many other murals in Aarhus (Denmark) and those that were mapped in OpenStreetMap. You can also visit the project’s website.

Open Data

  • At the State of the Map US conference, Jacob Whall raised concerns, in a direct conversation with members of the Overture Maps team, regarding the organisation’s apparent failure to fully comply with the OSM project’s Open Database License. In response, Overture representatives acknowledged and apologised for certain oversights, and gave a verbal commitment to address the issues and implement necessary corrections.

Software

  • BeardMD was disappointed with the apps used for hiking the St James Way (Camino de Santiago). These apps ask users for updates to opening hours or bed counts, but never contribute the information gained back to OSM. To fix that he has written the Camino App, which does contribute back, starting with fountain potability information.
  • Ralph Straumann reported that Cadence Maps is currently developing a new cloud-native data service for distributing OSM data in the Germany–Austria–Switzerland–Liechtenstein region. The service delivers data in the GeoParquet format using a unified schema modelled after the Overture Maps framework.
  • The first public test build of CoMaps is now available for iOS!
  • HeiGIT reported that their online dashboard ohsomeNow Stats has been updated. The dashboard now provides near real-time access to all OpenStreetMap contributions since 2005 without the need for hashtags, enabling more flexible and detailed analysis of global mapping activities.
  • novaTopFlex tooted about the novaMapTerm, an application written in Go, with the Fyne toolkit, combining the Linux terminal with OpenStreetMap data. Watch a demonstration video.
  • VersaTiles tooted about a website that compares vector tiles for OpenStreetMap. It was developed with planetiler-shortbread, a Docker image containing planetiler and VersaTiles vector tiles. The code is available on GitHub and the demo is accessible as well.
  • mondstern tooted about the PublicArtExplorer, an application developed by Thomas Zell that allows you to discover and explore public art around you in just two clicks. The app uses your location to instantly reveal nearby sculptures, murals, and installations, complete with detailed information about each piece and its artist. The PublicArtExplorer’s data is based on OpenStreetMap and Wikipedia and is available for Android.
  • What’s new on the OpenStreetMap website since mid-May? It’s now easier to get directions, link to your social media profiles, set your preferred language, and much more.

Programming

  • Paul Norman showed how he can identify when coastlines have changed, which was required for the OSMF Shortbread vector tiles. He stated that every few days about 1000 coastline tiles need re-rendering.

Releases

  • TrickyFoxy has published better-osm-org 1.0.0, which includes: rendering of type=restriction relations, displaying information about deleted users, filtering notes on the map, a ruler for measuring distances on the map, and the ability to move node POIs. Previous updates had also added links to 3D renderings of buildings, the ability to partially revert changesets via osm-revert, and filtering changesets in the user’s heatmap. The source code is available on GitHub.
  • A completely new release of Tracesmap has dropped. Its main feature has pivoted to a GPX file viewer.
  • Version 1.15.0 of Baba, the Panoramax Android app, has been released and now supports the Taiwanese Panoramax instance.

Did you know that …

  • [1] … jaz-michaelking has developed ‘Fediverse Near Me’? It is an interactive web map showcasing a curated list of well-moderated Mastodon servers open for registration and tailored to specific countries, regions, or languages.

Other “geo” things

  • AllTrails has launched an AI-powered feature that allows users to create custom hiking routes from scratch, modify existing trails, or utilise a new routing system to make hikes shorter, less steep, or more scenic. While the feature is designed to enhance user experience, search and rescue officials have warned that it could worsen a long-standing problem: hiking apps spreading inaccurate or misleading trail information. Environmental advocates have also raised concerns that the feature could encourage users to create unofficial trails wherever they please, emphasising that trails exist for a reason, as staying on designated paths is not only important for human safety but also for protecting entire ecosystems, which often rely on carefully planned trail designs to allow limited, sustainable access.
  • A research team, led by Ed Hawkins and the University of Reading, maintains an interactive map, #ShowYourStripes, which shows the rise in average temperatures around the world. Stripes turned from mainly blue to mainly red in more recent years for virtually every country, region, and city. The application uses OpenStreetMap as base layer.
  • The National Remote Sensing Centre of the Indian Space Research Organisation is hosting a free webinar on Bhuvan, the country’s web-based geospatial platform. The webinar is from 9 to 11 July and registration closes on Wednesday 1 July.
