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
