Geodesy

The Wolfram Language provides state-of-the-art high-precision geodesy computation, supporting all standard datums and projections.

DMS etc. Conversions

FromDMS — convert from degrees, minutes, and seconds to decimal degrees

DMSString, DMSList — convert from decimal degrees to degrees-minutes-seconds form

Latitude, Longitude, LatitudeLongitude — extract latitude, longitude

Degree (°) — conversion factor from radians to degrees (entered as deg)

Geodetic Points & Coordinate Systems

GeoPosition — geodetic position specified by latitude and longitude

GeoPositionXYZ  ▪  GeoPositionENU

GeoGridPosition — projected position in a cartographic grid

GeoAntipode — antipode of a geodetic location

Geodetic Paths & Measures

GeoDistance — distance between geodetic positions

GeoDirection — azimuthal direction between geodetic positions

GeoDestination — position at a given distance and direction from a point

GeoDisplacement — symbolic representation of a geodetic direction and distance

GeoLength — length of a geodetic path

GeoArea — area of a geodetic region

GeoDistanceList — successive pairwise distances between a list of geodetic positions

Geodetic Projections

GeodesyData — data on reference ellipsoids and geodetic datums

GeoProjectionData — data on cartographic projections

GeoElevationData — elevation data for the Earth

GeoGraphics — create detailed relief, border, street, etc. maps

GeoImage — satellite imagery
