# filters.gridprojection¶

The Grid Projection filter passes data through the Point Cloud Library (PCL) GridProjection algorithm.

GridProjection is an implementation of the surface reconstruction method described in [Li2010].

## Example¶

{
"pipeline":[
"input.las",
{
"type":"filters.gridprojection"
},
{
"type":"writers.las",
"filename":"output.las"
}
]
}


## Options¶

None at the moment. Relying on defaults within PCL.
