My best guess if I were to program the algorithm would probably be:
1) get xyz coordinates
2) do the depth contour shading thing - topography colouring (available open source)
3) somehow get the boundary coordinates where the colors intersect
4) adjust/approximate as necessary.
Why bother, you ask? I have access to hydrosurveyor's data (x,y,z coordinates) and wondering if it is possible to convert to quickdraw format and upload it to a garmin MFD.
