i have 500 points in this format and only i need 100.
Somebody can tell me how can i do that? I want delete some LAS points of my draw
Thank you very much for your colaboration
Well, I guess you can't crop a .LAS file in Autodesk environment, while it's possible with opensource software.
A clever workaround would be the following:
- download a trial version of Autocad Civil3D
- import and index your point cloud
- create a surface based on it
- add a "cutting" boundary to that surface.
You'll get no cropped .LAS file, but better than nothing, sir.
I was just working on a Lidar file earlier today in MAP 2012 and noticed that there was a command to do a Spatial Filter when indexing the file. Unfortunately, it's another function of MAP that doesn't work very well. I kept getting error messages and gave up on trying to do a location filter.
If you were to consider third party software, MapWorks Surfaces contains a Mass Points Processor that will let you select multiple LAS files and a bounding object or rectangle. If a LAS file hits outside the boundary it's ignored completely (for speed).
