Radial horizontal offset with height Offset expressed as a distance along a ray that originates from a central point with a third coordinate that indicates the height above the earth or water surface. The angle of the ray is expressed as the first offset coordinate in degrees. The distance along the ray is expressed as the second offset coordinate. The height above the earth or water surface is expressed as the third coordinate. 3D ODM2 Spatial Offset Type Controlled Vocabulary ODM2 Working Group A vocabulary for describing the type of SpatialOffset that exists between two SamplingFeatures.
