OSM research

Bobby Xiong et al. modelled the European high-voltage grid based on OpenStreetMap data.
HeiGIT reported that they have conducted a data quality assessment of open source data (including OSM) using their ohsome quality API. They analyzed aspects such as currentness, completeness, comparison with external datasets, and the activity of OSM contributors. The results of the analysis were to support the efforts of the World Bank to develop an analytical tool, the Gender Enabling Environments Spatial Tool, designed to assess localities based on how supportive they are in enabling women to access employment or business opportunities in the renewable energy sector.

Software

Rudo Kemper has created a webpage to convert Google Maps GeoJSON data into GPX and KMZ files, allowing them to render properly in Organic Maps.

Releases

Sarah Hoffmann announced the release of version 4 of pyosmium, a Python wrapper for the Osmium C++ library, used for reading, writing, and processing OSM data. This major update includes several new features, such as iterative processing, filter functions, and an OSM data writer with automatic reference completion.

Did you know …

… that you can geolocate an image by comparing the height of an object with the length of its shadow?
…that there is an in-depth course on validating OSM data on the UN Maps Learning Hub? It has been available since the beginning of the year and was used for a 20-hour training course organised over several weeks, followed by weeks in which participants applied their new knowledge. To access it, you will need to create an account on the Moodle platform used by the UN Maps Learning Hub.

OSM in the media

[1] Diario Norte, a online news outlet based in Argentina, reported ► that Federico Pértile mapped 629 trees (while also identifying the species of each one), 324 streetlights, 268 benches, and 74 trash bins around the Plaza 25 de Mayo de 1810 in Resistencia City, Argentina, on OpenStreetMap and then shared a 3D map visualisation of the area.
OpenStreetMap data powered The Washington Post’s story about the size and territory of supermarket chains in the US.
