HeyWhatsThat

3D mountain panoramas that label peaks for any viewpoint. Match a skyline in a photo to rendered terrain to geolocate outdoor images.

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.

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.

3D globe with high-resolution satellite imagery, 3D buildings and terrain. The desktop Pro version adds historical imagery, which you need for change-over-time analysis.

Open, crowdsourced street-level imagery (formerly OpenStreetCam). A useful second source when Street View and Mapillary coverage is thin.

Crowd size estimator. Draw the area a crowd occupies on a map, set a density per square metre, and get a defensible estimate of attendance.
