filters.splitter

The splitter filter breaks a point cloud into square tiles of a size that you choose. The origin of the tiles is chosen arbitrarily unless specified as an option.

The splitter takes a single PointView as its input and creates a PointView for each tile as its output.

Splitting 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).

Example

{
  "pipeline":[
    "input.las",
    {
      "type":"filters.splitter",
      "length":"100",
      "origin_x":"638900.0",
      "origin_y":"835500.0"
    },
    {
      "type":"writers.pgpointcloud",
      "connection":"dbname='lidar' user='user'"
    }
  ]
}
