geodata
Map-based digital facts
Geodata is information tied to geographic location—coordinates, boundaries, elevations, land use, population density.
The term covers everything from GPS readings to satellite imagery to census maps.
The app uses geodata to show nearby restaurants.
Also called geospatial data, particularly in technical contexts.
