smothing function for laser scanning generated contours

[dg0yt]

Somebody reported on Sourceforge [tickets:#152]:

it would be nice to have a smoothing function for contours generated with laser scanning data.

maybe while smoothing one contour, the neighbour contours should be heeded.

I'm not sure if this would be particularly useful. In the end the mapper still has to work on the contours and smoothing as post-processing of the generated lines will probably never turn out good because the algorithm cannot know which features are important and which can be smoothed. I imagine that intelligently redrawing the contours by hand could be the best way to get useful contours out of laser scanning data, especially in relatively flat terrain, but I never really worked with it.

A better way to automatize this could be to adapt the curves while generating them, so the height information is still available and can be used to base decisions on. For example, the amount of smoothing could then be controlled by the steepness of the terrain.
