[gdal-dev] Problem in importing to Google Earth a nitf image converted from a tif image by gdal_translate

Thu Apr 9 00:44:40 EDT 2009

Granted, I haven't tried V 5 yet, but your quote also states, "Google Earth
Pro or EC".  Are you using one of those versions of the client?  In any
case, if the file opens in OpenEV, chances are good that the .ntf generated
by gdal is ok, and that there is some sort of problem with how Google Earth
is reading it.  Have you tried emailing the KML support list as well?
