Geo referenced data
Geo referenced data (georeferenced data) is digital map, image, or raster data tied to an Earth coordinate system, via CRS standards like WKT and formats like GeoTIFF, enabling GIS overlay, distance and area analysis, and geocoding-adjacent workflows.

Geodetic datum
A geodetic datum is a coordinate system with a reference surface (ellipsoid or sea level) anchoring latitude, longitude, and heights. Key US datums: NAD 83, NAVD 88, WGS 84, ITRF, and the coming NATRF2022 modernization.
Geoglyph
A geoglyph is a large-scale design made by removing stones, digging trenches, or piling earth, and the best-known examples are the Nasca Lines of Peru.

Geographic center of the United States: balance point of all 50 states at 44°58'N 103°46'W, ~20 miles north of Belle Fourche, South Dakota, fixed in 1959 after Hawaii's statehood; the 48-state center lies near Lebanon, Kansas.
Geographic circque
Geographic cirque (glacial cirque; corrie, cwm): an armchair-shaped, glacier-eroded mountain hollow with a steep arcuate headwall and gently sloping floor, 200 m to 4 km across, used as a palaeoclimate indicator.
Geographic coordinate conversion
Geographic coordinate conversion changes coordinate values between reference systems with no change of datum, for example map projections, unit changes, or reformatting degrees-minutes-seconds as decimal degrees.
Geographic coordinate system
Geographic coordinate system (GCS): latitude-longitude angular coordinates on a reference ellipsoid, defined by datum, prime meridian, and unit. Covers WGS 84 (EPSG:4326), NAD 83, ellipsoid parameters, and the 1-2 m NAD83-WGS84 plate-motion offset.
Geographic Names Information System
The Geographic Names Information System, also known as GNIS, is the United States Geological Survey database of official geographic feature names, covering about one million places.
Geographical centre of Earth
Geographical centre of Earth: the geocenter, the Earth system's center of mass defining the ITRF origin, measured by satellite laser ranging, versus undefined surface geographic centers such as Europe's contested midpoints.
Geographical distribution of population
Geographical distribution of population, also called spatial or population distribution, describes where people live and how densely. Over 75% live in South/East Asia, Europe, and northeastern North America; cities now hold 45% of 8.2 billion people.
Geographical feature
Geographical feature: an identifiable representation of a natural, constructed, or administrative thing on or near Earth's surface, with location, type, and attributes; represented as points, lines, polygons, or raster cells, named in GNIS, and modeled by ISO 19109 and OGC standards.
Geographical midpoint of Europe
Geographical midpoint of Europe: disputed center points of the continent, claimed at Suchowola (Poland, 1775), Purnuškės near Vilnius (Lithuania, IGN 1989), Kremnické Bane (Slovakia), and Kremsmünster (Austria); location varies with Europe's defined borders and calculation method.
