it’s absolutely amazing to me how good lidar terrain mapping is. for bouldering, the quality of approach description makes the difference between walking straight in and finding that one block of rock in the middle of nowhere, and hiking up and down a steep hillside for an hour.

while topographical maps are invaluable for keeping one’s bearing (but blocks of rock are not mapped, and neither are all trails in the forest), and aerial photography maps are very useful (but of limited use here, where everything is forest), the terrain model regularly saves the day. unmapped trails? overgrown trails? blocks of rock covered entirely by the canopies? all there, clear as day. i love it. :)
