List of National Coordinate Reference Systems
The list of national Coordinate Reference systems (or list of official geographic projections, ...) lists geographic projections officially recommended for existing countries. Given that each geographic projection of a country and its spheric reality onto a plane surface generate specific and well known distances, shapes, areas deformations, each country needs are different in order to reduce these distortions. Also, each country, in order to represent its geographic space, need to choose a suitable, low distortion geographic projection. These national projections, or national Coordinate Reference Systems are officially announced by the relevant national agencies. The list below is a collection of available official national Coordinate Reference systems. For Europe, recommendation are available for each country (Annoni & al. 2001:43-44), as well as for the European Union of 15, of 27, and of the larger geographic Europe (Annoni & al. 2001:16). The most important project collecting geographic projections is the EPSG Geodetic Parameter Dataset project including about 4000 subjects and associated suitable projections, with notorious projections for all major countries. These projections and frames are publicly available online on various sites.[1]
