DEM to topographic contour lines

[Stephen Woodbridge]

I think you can do image classification using gdal to render pixels 
within a specified range with a specific color, which will simulate a 
contour map, but there is no code that I know of that computes contour 
lines on the fly. Look at the documentation on raster images, and pixel 
classification.
