# 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.
• 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.
