Hello,
How can I make contour maps?  I made contour lines by scaling down a
color_map but it does not have one color for a range of heights.

Try:

height_field
{
  tga "foobar.tga"
  smooth
  pigment 
  {
    gradient y frequency 20
    color_map { [0 rgb 0][0.9 rgb 0][0.9 rgb 1][1 rgb 1] }
  }
}

etc.

Thanks!  I rendered the contour map at 1280x1024.
