Shrink Wrap command works with Point Cloud Regions - if you select a point cloud region and apply Shrink Wrap to it, it will create you a boundary line. This is a great tool for stockpile work - check out this workflow
- Import a stockyard survey point cloud
- Do cleanup work on any area of the piles to be analyzed to eliminate unrequired data
- Use Point Cloud Processor to reduce the point cloud size by 90%
- Use the polygon select to create point cloud regions out of the pile areas, use Create Point Cloud Region to add the selected pile data to a new region e.g. Pile 1, Pile 2 etc. Note that if you create a polygon boundary for each pile rather than using polygon select then you will have the boundary lines for your piles (in 2D) to start off (you can then eliminate step 6 in this process) and use the Point Cloud by Boundary Command to create the point Cloud Regions.
- Use Point Cloud Clean Up tools to further eliminate data that is not representative of the ground surface or the pile from each Pile point cloud region.
- Now you have all the piles cleaned run the shrink wrap command on each pile to create a 3D boundary - note these 3D boundaries should represent the ground surface outside the pile base
- You can make a Ground Surface out of the 3D Boundary lines and a pile surface out of all the Point Cloud Region data
- Now run your Earthwork Report on the two surfaces with all the pile boundaries to get a volume on each pile
Hope you like the process
