Hi all,

I'm trying to crop a large (2.7 GB) point cloud (LAS) into smaller pieces -- appx 1 km x 1 km or 500 MB each. I've sectioned the LAS with "Create Regular Grid of Features" in the Digitizer, but when I export Vector/Lidar format, the LAS files are empty (1 KB).

I must not be selecting the proper layer for export. Does anyone have some pointers on how to make this happen?

Thanks!

    Hello,

    First, be sure to select the grid areas that you want to use for tiling. Then, on the Lidar LAS/LAZ Export Options screen under the Tiling tab, in the Tile Layout section, select the option: Use Selected Area Feature(s) for Tiles. Then complete the export. This should get you what you are looking for.

    Cheers,

    Bob
