| Krovak | | public class Krovak extends MapProjection (Code) | | Krovak Oblique Conformal Conic projection (EPSG code 9819). This projection is
used in the Czech Republic and Slovakia under the name 'Krovak' projection. The
geographic coordinates on the ellipsoid are first reduced to conformal
coordinates on the conformal (Gaussian) sphere. These spherical coordinates
are then projected onto the oblique cone and converted to grid coordinates.
The pseudo standard parallel is defined on the conformal sphere after its
rotation, to obtain the oblique aspect of the projection. It is then the
parallel on this sphere at which the map projection is true to scale; on
the ellipsoid it maps as a complex curve.
The compulsory parameters are just the ellipsoid characteristics.
All other parameters are optional and have defaults to match the common
usage with Krovak projection.
In general the axis of Krovak projection are defined as westing and
southing (not easting and northing) and they are also reverted, so if the
value of projected coordinates should (and in y, x
order in Krovak) be positive the 'Axis' parameter for projection should be
defined explicitly like this (in wkt):
PROJCS["S-JTSK (Ferro) / Krovak",
.
.
.
PROJECTION["Krovak"]
PARAMETER["semi_major", 6377397.155],
PARAMETER["semi_minor", 6356078.963],
UNIT["meter",1.0],
AXIS["x", WEST],
AXIS["y", SOUTH]]
Axis in Krovak:
y<------------------+

Czech. Rep. |

x
By default, the axis are 'easting, northing' so the values of projected coordinates
are negative (and in y, x order in Krovak - it is cold
Krovak GIS version).
