| Classification | Conical |
| Available forms | Forward and inverse, spherical and ellipsoidal |
| Defined area | Global, but more accurate around Czechoslovakia |
| Alias | krovak |
| Domain | 2D |
| Input type | Geodetic coordinates |
| Output type | Projected coordinates |
+proj=krovak
Note
All parameters are optional for the Krovak projection.
The latitude of pseudo standard parallel is hardcoded to 78.5° and the ellipsoid to Bessel.
+czech
Reverse the sign of the output coordinates, as is tradition in the Czech Republic.
+lon_0=<value>
Longitude of projection center.
Defaults to 24°50' (24.8333333333333)
+lat_0=<value>
Latitude of projection center.
Defaults to 49.5
+k_0=<value>
Scale factor. Determines scale factor used in the projection.
Defaults to 0.9999
