Graphics programs are not my strong point so I am a bit confused by the 200/50 meter settings.
I set those per the MicroDem tutorial but when I open the files in GIMP and check "image properties" it only show 72ppi for all the files. I tried changing them using "Scale Image" to 50 or 200 meters but when I reopen it after saving it is back to 72ppi. I then tried changing a small file to see if it was a GIMP memory problem and the same thing happened. Am I scaling it correctly, reading the wrong numbers, or is there another way to do it? (alos when I use Gimp's scaling function it asks what kind of interpolation to use and I went with the default "cubic")
Looking at Fly_z's BoB map it also shows 72ppi for the images in his folder??.
Also info on what are the requirements for the 2Dmap files would be appreciated. It appears they are supposed to be like:
ed_01 twice the height map resolution RGB
ed_02 same as map resolution RGB
