Subject: [UW-GIS-L] terrestrial lidar: surfaces or solids
I have terrestrial lidar data for a bunch of rocks in Beacon
Valley. Some of the data represent the undersides of rocks. How
can I build an accurate model? As some XY positions will have 3
or more Z values, a fully three-dimensional solid volume would be
ideal. An alternative would be to filter out underside points. I
can imagine filtering outlier points, but it seems hard to do
First choice: ESRI software
Second choice: something for my python toolkit
Third choice: other freeware.
Last choice: Buying something
