<DIV>Hello guys</DIV> <DIV> </DIV> <DIV>I checked the images with gdalinfo it gives me this result below but i tried two programs to open this image which are arcgis9.1 and Erdas both of them gave me that there is no coordinates, and projection system. yesterday i posted the first message because i checked the coordinates by using Erdas . </DIV> <DIV> </DIV> <DIV>still there is a problem here which is software compatapility.</DIV> <DIV> </DIV> <DIV> </DIV> <DIV> Projection=PROJCS["IMAGINE GeoTIFF Support<BR>Copyright 1991 - 2001 by ERDAS, Inc.
