I am long struggling with this projection. MapInfo does not support it, although it is well documented, for example, here is a WKT definition:

PROJCS["S-JTSK (Ferro) / Krovak",
    GEOGCS["S-JTSK (Ferro)",
        DATUM["D_S_JTSK_Ferro",
            SPHEROID["Bessel 1841",6377397.155,299.1528128]],
        PRIMEM["Ferro",-17.66666666666667],
        UNIT["degree",0.0174532925199433]],
    PROJECTION["Krovak"],
    PARAMETER["latitude_of_center",49.5],
    PARAMETER["longitude_of_center",42.5],
    PARAMETER["azimuth",30.28813972222222],
    PARAMETER["pseudo_standard_parallel_1",78.5],
    PARAMETER["scale_factor",0.9999],
    PARAMETER["false_easting",0],
    PARAMETER["false_northing",0],
    UNIT["metre",1]]

I think it is impossible to translate it to mapinfow.prj, because MI does not support Oblique Conic Conformal (at least I dont know).
The only way (so far) is to translate your data into other suitable projection by means of some translation utility, such as JTSKconv (www.terris.sk).

Hi

I recently received from Slovakia some DWG files which feature metre
coordinates. The coordinates are Southings and Westings i.e increase to
the south and to the west.
What systems are probable ?, could anyone point me at or provide, probable
MapInfo.prj file entries or failing that probable elements of same
ellipsoid (Bessel WGS84, ?), Datum, Projection.
Lastly I have one map the title of which includes UTM, this seems rotated
relative to the Krovak (?) maps so should I calculate affine parameters.


In short any advice would be gratefully received.

Regards

Brendan O'Donovan
