OpenCelliD

Crowdsourced map of cellular towers and coverage by carrier and technology (2G-5G), including estimated tower locations, sector bearings and frequency bands.

Crowdsourced database of hundreds of millions of geolocated Wi-Fi networks, Bluetooth devices and cell towers. Search by SSID or BSSID to map where a network has been seen.

No-code proximity search over OpenStreetMap. Pick features you can see in an image (e.g. a park, a tram stop, a tower) and a distance, and it returns every place where they occur together.

The official Copernicus Data Space Ecosystem viewer. Free access to the full Sentinel archive with visualisation, comparison, timelapse and download tools.

Archive of every published version of Esri's World Imagery basemap since 2014. Compare high-resolution satellite snapshots side by side to see when local changes happened.

AI photo geolocation that predicts where an image was taken from its visual content alone (architecture, vegetation, road features) and returns candidate regions or coordinates.
