Cadastre in Czechia.
Original definition. In CZ, remains legal system for cadastre, but for non-cadastral purposes replaced by S-JTSK/05 (Ferro) / Modified Krovak (CRS code 5224). In SK, deprecated and replaced by Greenwich-meridian equivalent CRS code 5513.
Cartesian 2D CS. Axes: southing, westing (X,Y). Orientations: south, west. UoM: m.
