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 (...)

That's right, you must set the scale of the image when you export from MicroDem to TGA format as written in tutorials. There you must set pixel spacing = 50m for map_c and 200m for other maps (T and h).

So map_C will come 4 times as large as map_T and map_h in both width and height (so 4x4=16 times larger in terms of number of pixels and file size).

Graphics programs won't tell you the scale in meters of your image, they simply don't know that it's the image of a portion of earth. For GIMP or Photoshop it's just as the picture of Pam Anderson
