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:
Thinning for OpenGL, and slices
KML vertical offset, to put the points above the landscape.
||Files list tab.
||Tools tab: Many 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.
- 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,
