The Overture Maps Foundation, founded in 2022 by Microsoft, Meta (formerly Facebook), Amazon, and TomTom, aims to provide accessible, interoperable open map data.
At the time of its launch I remarked that 'hopefully in the future the Overture Maps Foundation will develop more user-friendly methods to access the data'. The Overture Maps Explorer (Beta) is exactly that. The Explorer allows developers to zoom in on any location in the world and download a GeoJSON file of any combination of 'Land', 'Transportation', 'Buildings', 'Places', or 'Addresses' map data.
Using the Explorer couldn’t be simpler: just center the map on your desired location, select the layers you need, and hit ‘Download Visible.’ Instantly, you’ll receive the selected data for the current map bounds as a GeoJSON file.
Another similar tool is Evan Applegate’s Overture Data Grabber, which also simplifies the process of downloading Overture Maps data. After centering on your area of interest and choosing the desired data, simply draw a polygon around your selection. The Data Grabber then downloads the requested data as a GeoJSON file, ready for use.
To test out the Overture Data Grabber, I used it this morning to map the Brighton Lanes. I downloaded building footprints and place data, then paired it with road polylines from Overpass Turbo. Within minutes, I was able to create an interactive MapLibre map showcasing shops, bars, and restaurants in the Brighton Lanes - which, by lucky coincidence, also happens to qualify as my 'Points' map for the #30DayMapChallenge.
