    welllllllll...


    this gave me an idea, so here is my lunchtime project.

    I took my map from following the tutorial here (half way down the page):

    http://cartographersguild.com/forum/viewtopic.php?t=252

    Then I took the various layers and made a bump map. First by merging the hill layers, stretching the range from black to 50% gray.

    I then made copies of each layer I wanted to elevate separately, and either added them, or applied them normally to get the attached heightfield.

    I loaded this up in Povray (a most excellent ray tracing freeware, but having no modeler - everything is text files) as a height field, scaled appropriately.

    Then used the original image to paint the heightfield as an image-map. Added a semi-transparent waterline and a sky, and made the attached quick and dirty and absolutely free software version....

    Is this what you were thinking of?
