SU.935 CivilCraft: ground surface and contours from a drone point cloud
Asked: process drone point clouds the way a reality-capture program does, then make surfaces and contours (#935, Oct 23).
Today: clouds open (PLY, PCD, PTX, LAS; E57 partly, PF.1) and register (LC.3), and CivilCraft builds a ground TIN with contours from survey points (tin.js), but no step goes from cloud to ground. Do: thin the cloud to a grid, separate ground from objects (cloth or slope filter, with settings you can see), build the TIN, contours at your interval, volumes against a design surface; works on 50+ million points through the existing chunked reader.
