Its installation package includes databases of reference systems used in the world and in Russia (approximately 1500 reference systems). User can also add reference systems on his own by specifying:
-units (coefficient for transformation to meters or radians);
-ellipsoids (semi-axes or flattening);
-datums (parameters for transformation to WGS 84);
-map projections (parameters for the selected projection).

Main features:
-Albers;
-Cassini-Soldner;
-Gauss-Kruger;
-oblique Mercator and Hotine oblique Mercator;
-Lambert Conformal Conic (one and two standard parallels);
-modified Lambert Conformal Conic for Belgium;
-Mercator (one and two standard parallels);
-New Zealand Map Grid;
-oblique stereographic;
-polar stereographic;
-quasi-stereographic (Roussilhe);
-polyconic;
-transverse Mercator;
