horizontal reference system
- Definição1
- The horizontal reference system is the datum to which the positions of the data points are referenced. Coordinates used for air navigation must be expressed in the WGS-84 reference system. If the horizontal reference system is not WGS-84, the reference system and transformation parameters to WGS-84 must be specified.
