[GRASS-user] Orthophotos in .sid - removing black border

[stephen sefick]

I have orthophotos that are in .sid format.  I have converted them to
tif/tfw with the lizardtech software, but they have black borders.  I
would like to remove these borders so that I can use the orthophotos
in a tiled mosaic of the whole area of interest.  Any thoughts
suggestions, or help would be greatly apprecieated.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
