Geographic data and information

Geographic data and information are 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.[1][2]

It is also called geospatial data and information, georeferenced data and information, as well as geodata and geoinformation.

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:

gollark: Want to charge your laptop? Point your giant antenna dish in its general direction and enjoy losing most of the power and probably cooking yourself but enjoying the sheer freedom of not having to fiddle with the cables.
gollark: .
gollark: Yes, but at a distance for even better wirelessness
gollark: The solution is, of course, to move to wireless literally everything.
