Following a ridgeline [message #60897]

Hi,

I've got a 2d map (let's say it's a contour map of a mountain). I
need to be able to 'detect' and 'follow' the ridgeline across the
whole mountain (which does about a 180 degree turn as well, it's U
shaped). Anyone know any way to accomplish this?

So far, i've attempted to start at the maximum point, and then look
for surrounding points that minimizes the downward slope, this
process, however, creates switchbacks at peaks and doesnt follow the
peak down along a ridge. Any ideas?

Thanks!
