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]

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

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: <@579738672379854868> Is this one of those pyramid schemes where you get rewards by inviting people or something?
gollark: ... why? Nobody has asked for this so it makes you seem like an advertising bot.
gollark: That's actually pretty good because it's not copyable and impossible to fake.
gollark: I have one which uses asymmetric cryptography stuff - private key on the disk/card, public key stored... publicly - which means it doesn't need a server and can just pull off HTTP, but this is also neat.
gollark: Oh cool, a good keycard door lock program.
