alg install pdal/filters_dem
filters.dem uses a raster to keep data within a range of the raster cell. For example, atmospheric or MTA noise in a scene can be quickly removed by keeping all data within 100m above and 20m below a pre-existing elevation model. This algorithm is ported from the excellent PDAL - Point Data Abstraction Library. For more information please refer to https://pdal.io.
|band||GDAL Band number to read (count from 1)||integer|

|limits||A Range that defines the dimension and the magnitude above and below the value of the given dimension to filter. The following example would keep all Z point cloud values that are within 100 units above and 20 units below the elevation model value at the given X and Y value: Z[20:100]||string|
