Geospatial Technologies

Geospatial technologies are systems that acquire and handle location-specific data about Earth. Remote sensing, the global positioning system (GPS), and geographic information systems (GIS) are important geospatial technologies. Remote sensing and the GPS are methods for collecting information about Earth's surface; GIS ia a mapping tool for organizing and analyzing information.

Remote Sensing

All methods of collecting information about Earth without touching it are forms of remote sensing. For example, photographing a flooded river from an airplane is a form of remote sensing, but sampling its water is not. Scientists mount remote-sensing devices such as ...
