The list of national coordinate reference systems (CRS) lists
map projections officially recommended for
existing countries. Given that every projection gives deformations, each country's needs are different in order to reduce these distortions. 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 projected Coordinate Reference Systems. Links to the relevant unique identification codes of the
EPSG Geodetic Parameter Dataset, the most comprehensive collection Coordinate Reference Systems, are provided in the table.
