Filter the surface points
This function is superseded by the algorithm highest usable in decimate_points
filter_surfacepoints(las, res)
las |
An object of class LAS or LAScatalog. |
res |
numeric. The resolution of the grid used to filter the point cloud |
If the input is a LAS object, returns a LAS object. If the input is a
LAScatalog, returns a LAScatalog.
Supported processing options for a LAScatalog (in bold). For more details see the
LAScatalog engine documentation:
chunk size: How much data is loaded at once.
chunk buffer: This function guarantee a strict wall-to-wall continuous output. The buffer
option is not considered.
chunk alignment: Align the processed chunks.
progress: Displays a progression estimation.
output files*: Mandatory because the output is likely to be too big to be returned
in R and needs to be written in las/laz files. Supported templates are {XLEFT}, {XRIGHT},
{YBOTTOM}, {YTOP}, {XCENTER}, {YCENTER} {ID} and, if
chunk size is equal to 0 (processing by file), {ORIGINALFILENAME}.
select: The function will write files equivalent to the original ones. Thus select = "*"
and cannot be changed.
filter: Read only points of interest.
Other filters:
filter_duplicates(),
filter_poi(),
