Workaround from the user:One difference is that in later versions we write out the BLOCKA TRE. There's a chance that this could be causing the problem. They can disable the writing of the BLOCKA TRE by setting the following registry entry and rechipping. WriteBLOCKA REG_SZ false By default the BLOCKA TRE will be written with every saved or chipped NITF image (if the image contains geo information). If this registry entry is set to false then the BLOCKA TRE will NOT be written. The BLOCKA TRE contains more actual geo corner coordinates than the standard IGEOLO field. .ie Using regedit, this goes under HKEY_LOCAL_MACHINE/SOFTWARE/Sensor Systems/RemoteView/Public string value WriteBLOCKA false
