Cad Earth Crack 2021 Page

Using a DJI Phantom 4 RTK, engineers captured sub-centimeter imagery of a 500m long fissure in a desert alluvial fan.

The drone data was stitched to produce a GeoTIFF and a dense point cloud. The resulting 3D mesh highlighted the crack's sinuous path. cad earth crack 2021

Use the _MAPTRACE tool in AutoCAD Map 3D 2021 to semi-automate the digitization of the crack centerline based on contrast differences in the raster image. Workflow 2: Modeling the Subsurface "Crack" Surface A surface trace is insufficient. Engineers needed to model the shear plane. In 2021, this was done using Feature Lines and Grading Tools . Using a DJI Phantom 4 RTK, engineers captured
