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":"([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]
