Geographic Information System. Software that permits visualizing and manipulating maps, associating data with places on the map, overlaying data, and analyzing various features of the combination.

A preeminent company in the GIS field is ESRI. There are FOSS GIS software packages that can be localised (such as GRASS).

GIS is a specialised technology, but the software is becoming more user-friendly. Its use is becoming more frequent in local development projects using participatory methodologies (see PPGIS).
