This will probably sound simple to some of the folks, but its still a matter of confusion for me.. <br><br>I have a GTif file with the following metadata as from gdalinfo utility (in a few a lines):<br><br>I would appreciate if anyone could help me in telling me how I can possibly derive 4 GCPs using the <br>
GRINGPOINTLATITUDE, GRINGPOINTLONGITUDE metadata fields or possibly the metadata in:<br> EASTBOUNDINGCOORDINATE=134.930768655651<br>

NORTHBOUNDINGCOORDINATE=64.7989342568829<br>
SOUTHBOUNDINGCOORDINATE=20.7060304288409<br><br>I just dont get what kind of calculations / transformations are required to be done in order to derive the GCPs for reprojection...<br><br>gdalinfo output: <br><br>Driver: GTiff/GeoTIFF<br>
