WTrans Projections and Coordinate conversions

(B,L,h) <-> (X,Y,Z) computations
Ellipsoidal confocal coordinates <-> (X,Y,Z)
Alternatively an automatic detection or a manual selection of reference meridian in case of Gauss-Krüger and UTM.
Different Map Projections (B, L) <-> (Eastern, Northern)

General types of projections: UTM, Gauss-Krüger, Mercator, Lambert, Soldner

Country-specific projection-realizations: Lambert Belgium 2005, Lambert Estonia, Lambert France 1993, Gauss-Krüger Austria, Switzerland conformal double-projections (LV95 and LV03+), EOV Hungary
