"Geospatial" redirects here. For other uses, see Geospatial (disambiguation).

Geographic data and information is defined in the ISO/TC 211 series of standards as data and information having an implicit or explicit association with a location relative to Earth (a geographic location or geographic position).[1][2]

It is also called geospatial data and information,[citation needed] georeferenced data and information,[citation needed] as well as geodata and geoinformation.[citation needed] geospatial data and information includes hydrospatial data and information

Approximately 90% of government sourced data has a location component.[3] Location information (known by the many names mentioned here) is stored in a geographic information system (GIS).

There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data.[4]

Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced, such as in computer-aided design (CAD), see geometric modeling.

Fields of study

Geographic data and information are the subject of a number of overlapping fields of study, mainly:

This is in addition to other more specific branches, such as:
