[GRASSLIST:529] Re: DEM Generation from stereo optical imagery

[Gerald Buckmaster]

Markus,

Wow, everyone else must have interest in the link you provided!  I'm getting 
the ever-popular Error 503 - Too many users.  Is that common with 
grass.itc.it?  It appears to be mirrored at 
http://grass.ibiblio.org/gdp/stereo-grass/ for anyone who hasn't figured that 
out yet. I'll have time to read it tonight.

Thanks for the link Markus!

Gerald
