envitia::maplink::earth::GeodeticDirection Class Reference

Inheritance diagram for envitia::maplink::earth::GeodeticDirection:

Detailed Description

A direction in geodetic (ENU) space

This class is used to specify a direction vector in East-North-Up (ENU) space

• x: longitude in WGS84
• y: latitude in WGS84
• z: altitude in meters, relative to the ellipsoid

Note

Due to the nature of this coordinate system a direction in ENU space does not correspond to a straight line in ECEF space, or visually. In addition modifying the length of this class will affect the direction in relation to other coordinate spaces.
