Hello all,<div><br></div><div>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.</div>
<div><br></div><div> Part of the gdalinfo output is:</div><div><br></div><div><br></div><div><br></div><div>_________________________________________________________________</div><div><br></div><div><div>PROJCS["UTM",</div>

<div><br></div><div><br></div><div>________________________________________________________________</div><div><br></div><div>As you see the geographic coordinate system don't translate the corners projected coordinates into the geographic ones.</div>
<div><br></div><div>Am I missing a parameter or is some concept wrong with the chosen wkt ? </div><div><br></div><div>Many thanks in advance.</div><br>-- <br><span style="border-collapse:collapse;font-family:arial, sans-serif;font-size:13px">Ing. Rodolfo Bonnin<br>
