# filters.decimation¶

The decimation filter retains every Nth point from an input point view.

## Example¶

{
"pipeline":[
{
"filename": "larger.las"
},
{
"type":"filters.decimation",
"step": 10
},
{
"type":"writers.las",
"filename":"smaller.las"
}
]
}


filters.voxelgrid provides grid-style point decimation.

## Options¶

step
Number of points to skip between each sample point. A step of 1 will skip no points. A step of 2 will skip every other point. A step of 100 will reduce the input by ~99%. [Default: 1]
offset
Point index to start sampling. Point indexes start at 0. [Default: 0]
limit
Point index at which sampling should stop (exclusive). [Default: No limit]
