GeoPositionENU

GeoPositionENU[{east, north, up}, p]
represents a point with local Cartesian coordinates {east, north, up} in a reference system specified by the position p.

MORE INFORMATION

GeoPositionENU[{e, n, u}, GeoPosition[{lat, long, h}, datum]] uses a geodetic position to specify the origin of an ENU point.

Coordinate values are assumed to be in meters.

Typical values for datum specifications include "ITRF00", "NAD83CORS96", and "WGS84".

GeoPositionENU coordinates are assumed to have a time coordinate equal to the reference epoch date of the datum that specifies the origin.

GeoPositionENU[GeoPositionENU[{x, y, z}, p₁], p₂] converts between two different ENU systems.

GeoPositionENU[coord, p] converts any coordinate type to an ENU position.

Mathematica supports the following geographic coordinate types: GeoPosition, GeoPositionENU, GeoPositionXYZ, GeoGridPosition.
