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]
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]
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:
- Cartography
- Geodesy
- Geography
- Geostatistics
- Photogrammetry
- Remote sensing
- Spatial data analysis
- Surveying
- Topography
