Coordinate Operations affect Geometrical Relationships
The taxonomy for classifying mathematical trans-formations is complex and there are many types:
- isometric, linear, bi-linear, conformal, orthogonal, affine, isomorphic, ...
For SEDRIS, two classifications are sufficient for operations associated with SRFs:
- Geometry Preserving Operations (GP): That class of operations among spatial reference frames that do not distort geometrical relationships
- Geometry Distorting Operations (GD): That class of operations among spatial reference frames that distort some geometrical relationships
