Mett,<br><br>If I understand correctly, you need to remove the black borders of geotiff and reset the corner coordinates. GDAL's nearblack utility[1] might be of help to you.<br><br>[1]: <a href="http://www.gdal.org/nearblack.html">http://www.gdal.org/nearblack.html</a><br>

Hello Everybody!<br>
Does somebody know if there is a smart way to get the coordinates of a<br>
GeoTiff of the real data (avoinding the black background)? I mean, I have<br>
the geocoordinates of the image, but they are not referred to the "Real"<br>
data of the image but just to its corners. I know that I can use gdalwarp to<br>
set trasparency of black area, but I think it is not suitable to re-set the<br>
coordinates.<br>
<br>
Thank you for any help!<br>
Mett<br>
