Hello all,
I'm trying to define a UTM projected coordinate system, with a custom
geographic coordinate system, to have a system similar to the geocentric
ITRF97, in gdal 1.8, which doesn't support that type.
Part of the gdalinfo output is:
_________________________________________________________________
PROJCS["UTM",
GEOGCS["ITRF97 (wgs84 equivalent)",
DATUM["International_Terrestrial_Reference_Frame_1997",
SPHEROID["GRS 1980",6378137,298.257222101,
AUTHORITY["EPSG","7019"]],
TOWGS84[0,0,0,0,0,0,0],
AUTHORITY["EPSG","6655"]],
PRIMEM["Greenwich",0,
AUTHORITY["EPSG","8901"]],
UNIT["degree",0]],
PROJECTION["Transverse_Mercator"],
PARAMETER["latitude_of_origin",0],
PARAMETER["central_meridian",141],
PARAMETER["scale_factor",0.9996],
PARAMETER["false_easting",500000],
PARAMETER["false_northing",0],
UNIT["Meter",1]]
GeoTransform =
-14448629.2184734, -141.4557903812352, -1.43564504297578

________________________________________________________________
As you see the geographic coordinate system don't translate the corners
projected coordinates into the geographic ones.
Am I missing a parameter or is some concept wrong with the chosen wkt ?
Many thanks in advance.
