The Chipper Filter takes a single large point cloud and converts it into a set of smaller clouds, or chips. The chips are all spatially contiguous and non-overlapping, so the result is a an irregular tiling of the input data.
Note
Each chip will have approximately, but not exactly, the capacity point count specified.
.. seealso:: The :ref:`PDAL split command <split_command>` utilizes the :ref:`filters.chipper` to split data by capacity.
Chipping is usually applied to data read from files (which produce one large stream of points) before the points are written to a database (which prefer data segmented into smaller blocks).

- capacity
- How many points to fit into each chip. The number of points in each chip will not exceed this value, and will sometimes be less than it. [Default: 5000]
