Finally devised a way to confidently and easily extract profile data from the LiDAR data set in GlobalMapper. Surface profiles are simple. Basal profiles shown here are estimates based on some point measurements. Will vastly improve the basal profiles when GSA is over. Needed this figure, however, so spent too much time devising the method.

Only issue now is to develop a technique for efficiently normalizing all the profiles to a reference thalweg of some sort. Already have data in xyz, so a quasi 3-D diagram would be the most realistic.

Need to talk about this with the group.
