Hi folks,<br>
Maybe this question is old, but I don't find an answer on Internet.<br>
If I perform this command:<br>
<br>
gdal_translate -outsize 50% 50% -of GTiff -projwin<br>
1299378.2102987265 5588829.1661406181 1299486.6170906540<br>
5588715.6742054483 frmt_wms_googlemaps_tms.xml tempfile.tif<br>
<br>
the image obtained is perfect in term of area of interest, but the<br>
georeference is wrong if I open the image with ENVI.<br>
I think that it is caused for the "Google Maps Global Mercator", but<br>
I don't know how I can convert the projection to (for example) an<br>
UTM projection or something else. I tried to reproject using gdalwarp:<br>
<br>
gdalwarp -t_srs "+proj=utm +zone=32 +datum=wgs84" tempfile.tif<br>
tempfile-warp.tif<br>
<br>
but, still wrong georeference.<br>
<br>
Someone can help me?<br>
<br>
