Is there an easy way of taking a topographic map as yoinked from
Terraserver and making a heightfield of it such that each elevation
line and the space to the next line is a single greyscale?
The only way I have of accomplishing this at the moment is going
into PSP and manually putting in a vector point-to-point line over
each elevation line in a new layer...excessively time consuming.
I suppose I could try using a regular 1x1 paintbrush and my Wacom
tablet and drawing the lines in a new layer, but...if there's an
even easier way, I'd like to know about it!
