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: What are you saying is bees?
gollark: Well, it's a ZIM file or something, which contains compressed HTML and images.
gollark: Thanks to dubious apiotechnology you can now view an amazing 100 Wikipedia articles here: https://a.osmarks.tk/
gollark: I was able to find, *somehow*, what looks like the source of the FM radio native code/app from about four years ago on github.
gollark: I think it would be somewhere between "install original ROM's FM radio app as a privileged system app" (fine) and "reverse engineer SoC FM tuner and implement own frontend" (not doing that).
