Hi All,
I'm trying to prepare some ortho images for use in mapserver.  Basically
what I'm trying to do is merge together 2 ortho MrSid images that are
different resolutions.  The problem I'm having has to do with the MrSid
nodata value not being consistently 0 0 0 creating speckling in overlapping
areas(setting transparency to 0 0 0 filters out most "nodata").  Is there
away to mask overlapping areas or filter them?  Any advice would be great.

Travis
