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.
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.
Computes the visible horizon and viewshed from any point using elevation data, and labels the peaks you'd see. Helps confirm what's visible from a claimed location.
Open, crowdsourced street-level imagery (formerly OpenStreetCam). A useful second source when Street View and Mapillary coverage is thin.
Crowdsourced street-level imagery platform with billions of images, often covering roads, trails and countries that Google Street View doesn't reach. Filterable by capture date.
