Hello to all. Merry Christmas and so forth.
I use Manifold which allows me to take surfaces I've
imported, copy and paste the surface as an image for
all kinds of image manipulation and such.
I've been using MicroDEM to merge and then export the
DEM's in my AOI as a DTED1 file. I'm still learning
how to play with the "output lat/long interval" level
and thought it might give me greater control to just
merge the two using somewhat traditional Photoshop
techniques, only I've run into a little problem.
Some DEM's seem to have a border or something around
them and when I manually merge them I get a visible
seam. Of course, MicroDEM merges them beautifully
which leads me to believe there's some sort of
overlapping data but I'm not sure.
Can anyone clear up this question for me? Also, if you
have a technique you'd like to share I'd be more than
happy to give it a try.
Thanks!
