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).[https://isotc211.geolexica.org/concepts/202/ Geolexica, the authoritative glossary for geographic information technology from ISO/TC 211][https://isotc211.geolexica.org/concepts/205/ Geolexica, the authoritative glossary for geographic information technology from ISO/TC 211] It is also called geospatial data and information,{{citation needed|date=July 2016}} georeferenced data and information,{{citation needed|date=July 2016}} as well as geodata and geoinformation.{{citation needed|date=July 2016}}

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.

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:

"Geospatial technology" may refer to any of "geomatics", "geomatics", or "geographic information technology."

The above is in addition to other related fields, such as:
