Warning

As of PDAL v2.6.0, the delta command is marked as DEPRECATED. It will be removed from the default install in PDAL v2.7 and removed completely in PDAL v2.8.

The delta command is used to select a nearest point from a candidate file for each point in the source file.

$ pdal delta <source> <candidate>

--source           source file name
--candidate        candidate file name
--detail           Output deltas per-point
--alldims          Compute diffs for all dimensions (not just X,Y,Z)

Example 1:

$ pdal delta ../../test/data/las/1.2-with-color.las \
    ../../test/data/las/1.2-with-color.las
