- Stamen discussed the implementation of motorway shields for Amazon Location maps (which use OpenStreetMap data with the attribution hidden), explaining the complexity of designing accurate and recognisable shields due to variations in data consistency and tagging conventions between countries. The article highlighted the process of creating these shields, the challenges posed by inconsistent data, and how these elements add valuable detail and context to map designs.
- The GeoPortal München presented ► an interactive map of ‘cool places’ in München, Germany, to help residents find places with shade, water, and cooler temperatures, which is especially useful during heat waves.
- This interactive map visualises the birthplaces of 2024 Summer Olympics medallists, allowing users to explore the geographical distribution of athletes by region of origin. The map provides insight into which areas have produced the most medallists, offering a detailed view of regional sporting achievement.
OSM in action
- [1] Andreas Scherbaum has found an OSM-based hiking map in Birkenwerder, Germany, with correct attribution.
- Albileo has taken hundreds of photographs of aircraft. You can view their photo spots ► around Narita International Airport, Tokyo, Japan, on an OSM-based map.
Software
- William Edmisten reviewed six open source tools for querying OpenStreetMap data, including overpass turbo for web-based filtering, osm2pgsql combined with PostGIS for geospatial database queries, DuckDB’s experimental
ST_ReadOsm()function for direct file queries, QLever for RDF-based querying with SPARQL, Nominatim for geocoding based on textual input, and Pelias, which uses Elasticsearch for robust geocoding. William discussed the strengths, limitations, and setup procedures of each tool. - HeiGIT reported that the Initiative for Safer Roads has developed a digital school route planner , with the primary goal of improving road safety on school routes in Germany. The digital school route planner uses an OSM-based Germany-wide map of danger spots, which incorporates accident data from the police, reports from road users, and other factors, as well as HeiGIT’s openrouteservice API.
- Keir Clarke explored how OpenStreetMap data is being used to create immersive virtual reality experiences, such as osm4vr and VR Map, which allow users to navigate through a 3D world using OSM map tiles and building footprints.
- fltb’s first bi-weekly report on their OpenStreetMap public transport relational editor project detailed development progress, successful point and path rendering tests, and challenges such as integrating a custom user agent for tile requests, with plans to further develop the editor module for API communication.
Programming
- Try Catch Debug explained how to import OpenStreetMap layers into ArcGIS Server using JavaScript, detailing the steps to find OSM layers, use the ArcGIS API for JavaScript to integrate these layers, and customise ArcGIS Server with additional infrastructure layers.
- GeeksforGeeks explained how to use Leaflet to interact with maps in JavaScript, covering key concepts such as creating maps, adding markers, and implementing interactive features such as pop-ups and event handling, with sample code and step-by-step instructions.
- Hyumika’s OpenStreetMap plugin for WordPress, up to and including version 6.0.2, is vulnerable to SQL injection via the
tagged_filterattribute, allowing authenticated users with contributor level access or higher to execute additional SQL queries and potentially extract sensitive data. - c6tower(み) explained ► how to implement a web application for route searching using Valhalla and Leaflet, detailing the setup process using Docker, Python, and OpenStreetMap data, while demonstrating how to perform route searches and visualise the results on a map.
Releases
- Nominatim has released a new Wikimedia-based scoring file that uses data from Wikipedia and Wikidata to assign importance scores to places, allowing for more accurate geocoding, with the updated file now available in a streamlined CSV format.
Did you know …
- … OpenStreetMap has ‘good practices‘ guidelines?
- … that every three hours, the @rcityviews X (formerly Twitter) account will feature a randomly chosen city map from around the world using data from OpenStreetMap?
OSM in the media
- stern discussed ► the potential of outdoor apps, such as those using OpenStreetMap, to improve conservation efforts. DieBayern.de News highlighted ► that OSM often lacks specific information about protected areas. Collaboration between app developers and conservation authorities could improve data accuracy and help users avoid disturbing sensitive areas. By incorporating clear guidelines and temporary restrictions into maps, and using data from user interactions, apps can better manage ► visitor flows and support conservation through initiatives such as citizen science projects.
Other “geo” things
- Minnesota Governor Tim Walz, a former geography teacher and current US vice-presidential candidate, is passionate about maps and GIS, which he believes are critical to data-driven policymaking in areas such as education and public safety. He uses maps extensively to communicate with constituents and inform policy decisions, and criticises oversimplified red-blue political maps for their divisive effects. Walz emphasises the importance of GIS in translating visions of social justice into tangible results.
- Truevision Designer is a versatile tool for creating detailed maps for simulation, robotics and training, with tools for intersections, signal editing and exporting to platforms such as CARLA, with free and premium options available. Version 2024.8 introduced improved lane marking support, enhanced OpenDrive geometry imports, a new Super Elevation tool for realistic road slopes, and significant improvements to the junction creation process, including custom junction and connection tools.
