Recent OGC documents prefer the term "Coordinate Reference System" in situations that previously referred to "Spatial Reference System" or even "Projection".
We should review the usage of the term "Projection" in the cases where CRS is actually a more descriptive term.
The semantic difference between SRS and CRS is contrasted by the following ISO Standards:
- Spatial Referencing by Coordinates ( ISO 19111:2003 ) - e.g. http://loki.cae.drexel.edu/~wbs/ontology/iso-19111.htm
- Spatial Referencing by Geographic Identifier ( ISO 19112:2003 ) - e.g. http://loki.cae.drexel.edu/~wbs/ontology/iso-19112.htm
An SRS could refer to an address-based lookup scheme (as well as a coordinate-based lookup scheme) - therefore what QGIS currently deals with are more accurately called CRSs.
