Example

  1. Consider a SEDRIS transmittal that contains an <Environment Root> instance, the ORM of which is ORM_MULTIGEN_FLAT_EARTH_1989, so that its srf_info field of ER is specified in the Equidistant Cylindrical SRF. An <EC Augmented 3D Location> instance within this SRF might be easting = 30.0, northing = 50.0, ellipsoidal_height = 100.0.
