# GeoPositionENU

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

GeoPositionENU[{{e1,n1,u1},{e2,n2,u2},},p]
represents an array of positions.

GeoPositionENU[entity,p]
returns the Cartesian position with respect to p of the specified geographical entity.

## DetailsDetails

• GeoPositionENU[{e,n,u},GeoPosition[{lat,lon,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[{e,n,u,t},p] includes a time t measured in seconds since the beginning of January 1, 1900 in the GMT time zone.
• A GeoPositionENU object with no explicit time assumes the current date.
• GeoPositionENU[GeoPositionENU[{x,y,z},p1],p2] converts between two different ENU systems.
• GeoPositionENU[pos,p] converts any position type to an ENU position.
• The Wolfram System supports the following geographic position types: GeoPosition, GeoPositionENU, GeoPositionXYZ, GeoGridPosition.
