SRM Conceptual Relationships
Object independent aspect:
- An abstract coordinate system (CS) is based on the underlying Euclidean structure of position-space.
Object empirical measurement/model dependent aspect:
- The reference datums bound to an object determine how position-space relates to object-space.
- The relationship may be mathematically expressed by a normal embedding.
- The relationship is specified as an object reference model (ORM).
Combined as a spatial reference frame (SRF)
- An SRF combines an abstract CS with an ORM to specify a spatial coordinate system.
