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

[mohwawang]

Hi all,

I used gdal_translate to convert a tif image to a nitf image as:
>gdal_translate -of nitf in.tif out.ntf -co ICORDS=G
Input file size is 561, 420
0...10...20...30...40...50...60...70...80...90...100 - done.

I can display both in.tif and out.ntf with OpenEV. So both in.tif and out.ntf 
were ok to OpenEV.

With a simple Google Earth kml file(specifying the LanLonBox)(printed below) I 
could import the in.tif to Google Earth viewer to the right geo-location. So 
in.tif was ok to GE. 

However, after replacing the image file name from in.tif to out.ntf in the same 
kml file (printed below) I could not import the out.ntf to Google Earth viewer 
(shown as a big red cross in a big red rectangle at the geo-location in the GE 
viewer). So out.ntf was not ok to GE. Any ideal about what might cause the 
problem? Was the use of gdal_translate wrong or missing some options? I tried 
not to use -co ICRODS=G but I got the same problem. Thank you.

printed kml for in.tif:
