[Gdal-dev] CADRG Problem

[Alan Ott]

Hello,

I have just recently started using GDAL to view CADRG data. I have 
several sets of data, and GDAL is able to load some of them perfectly. I 
am having trouble, however, with the data I downloaded from 
http://www.aeroplanner.com/cadrg/ (click the "Sample CADRG (2.78MB)" for 
a zip file). I put one of the files here 
(http://www.signal11.us/~alan/001DR00B.LF2) for download convenience.

The files load fine in Rockware's Global Mapper software 
(http://www.rockware.com . free trial download available), but produce 
weird images in my application. The weird images I get correlate with 
images produced by OSSIM's ivew and OpenEV 1.8 In (which uses 
GDAL).terestingly, ivew and OpenEV Seem to produce very similar images 
to one another (while not correct).

You can see screenshots here:

I don't currently have a pressing need to be able to view these 
particular files, so consider this somewhat of a bug report, although 
it's hard to say what kind of data I may need to view in the future.

Alan.
