Point Cloud Options

Points clouds are a category of GIS data.  This forms allow manipulation of the LAS point cloud.

Tabs provided detailed option selection:
Main controls on the bottom of the form, always visible:
  General tab. 

Thinning for OpenGL, and slices

KML vertical offset, to put the points above the landscape. 

Files list tab. 
Tools tabMany of these options require that the base map in use have a DEM associated with it, which will determine the size of the grid created.

Stats tab:

  • Histograms/Counts: histograms for elevation and intensity, and a count of the returns in each category, and by return number.
  • Zero classification: merge all LAS files in the current files listing into a single file, with the classifications all reset to zero.
  • RGB Palette:
  • Split by class: create new files by classification (vegetation, buildings, ground, non_ground, unclassified, and other)
  • Recenter files: recenter all coordinates so that multiple files share the same values.  This is designed for use with Cloud Compare, and not at this time to create usable LAS files for further analysis.
  • Subset/tile: recursively quarter files until all file sizes are under a specified value;
  • Zero fields : set the following fields to zero: Intensity, ReturnFlags, ScanAngle, UserData, PointSourceID
