Data Modelling of Map Projections

For creating a data model of map projections, first it needs a systematization of map projections.

Both, a systematization of map projections as well as data model of map projections is found in:

Stefan A. Voser
Konzeptuelle Modellierung von Koordinatensystemen für Geodateninfrastrukturen
(“Conceptual Modelling of Coordinate Systems for Geodatainfrastructures”)
More about this is found [here].
