filters.crop

The crop filter removes points that fall outside or inside a cropping bounding box (2D) or polygon. If more than one bounding region is specified, the filter will pass all input points through each bounding region, creating an output point set for each input crop region.

Example

{
  "pipeline":[
    "file-input.las",
    {
      "type":"filters.crop",
      "bounds":"bounds",
      "count":"([0,1000000],[0,1000000])"
    },
    {
      "type":"writers.las",
      "filename":"file-cropped.las"
    }
  ]
}

Options

bounds
The extent of the clipping rectangle, expressed in a string, eg: ([xmin, xmax], [ymin, ymax]) This option can be specified more than once.
polygon
The clipping polygon, expressed in a well-known text string, eg: POLYGON((0 0, 5000 10000, 10000 0, 0 0)) This option can be specified more than once.
outside
Invert the cropping logic and only take points outside the cropping bounds or polygon. [Default: false]
