[gdal-dev] Mosaicking Orthos

[Zoltan Szecsei]

Hi All,
I've built a vrt with 176 images.

I now need to mosaic this whole area into roughly 5 x 5 ortho images.

How can I force the white edges into background of the overlapping orthos?
I'm a little cautious of simply (finding a way to) making "white" 
transparent as it is only the white on the edges that need to be 
backgrounded.

Some pointers would be nice.

Thanks in advance,
Zoltan
