Problems with ossim bandMerge and blending, and then rendering with GDAL

[Tom MacWright-2]

Hi,

I've been trying to merge a lot of GeoTIFFs (merging three bands each  
for many) and then blending them together into one large nitf image,  
and I don't get any reported errors from ossim-orthoigen at all  
(running with mpirun -np 2 on both commands), but when I attempt  
rendering via GDAL, I get a very bizarre output - the bands stacked on  
top of each other and no coverage in the bottom half of the imagery.  
Here's what it looks like: http://skitch.com/tmcw/ndexn/combined.nitf-vimperator 
  . Any ideas for what might cause this? It's quite frustrating and  
I'm afraid that my current work will also suffer from the same bug or  
snag somewhere in the process.

Thanks!

Tom MacWright

Hello Top:

Could you define the exact process you want to do.  When you say merge  
are you mosaicing a number of tiffs together?  merging bands is  
different than doing a moasic for the bands are not aligned to a view  
since all inputs are of different geometries.


Take care and let me know.

Hi Tom,

Sorry for the late response I was waiting for you to respond to Garrett.

Via command line I would do:

ossim-band-merge tiff_tiled_band_separate b1.tif b2.tif b3.tif rgb.tif

I just check this does copy tags.  You can check with:

ossim-info -d rgb.tif

Then I would do the orthoigen.

ossim-orthoigen rgb1.tif rgb2.tif rgb3.tif mosaic.tif

You could also do this with "imagelinker" but it sounds like you want command line.

I can't speak for the gdal output.  You'd have to ping the gdal list on that.

Take care,
Dave
