Don't anyone let Dan cut off his ear! cool.gif
Thanks for the clue, Shaka. I found myself scratching my head while looking at Dan's work, wondering how that scoundrel achieved such a result. It's all so obvious, now. biggrin.gif

To the rest of you producing those amazing terrain recognition maps, keep it up. I'm seriously impressed by your ingenuity and I'm really excited with the maps I am seeing so quickly. This is one of the most interesting threads we've had around here in quite a while. I've noticed that some of the methods seem to do a better job of flagging the dangerous half-pipe pinch-offs as red territory. Were not Purgatory and Jammerbugt such geometry's? This exercise is not simply about large versus small drifts. wink.gif

I'd like to echo previous comments that we should adopt a standard color scale for these contour maps. That would make comparisons easier. Its probably a bit early to make judgments regarding the different methods being used, but so far, Fran's first color map is my favorite. The contours really seemed to hug the terrain changes.
