laser ground¶
Identifies and classifies ground points.
It's typically advised to run this routine only when the las/laz data does not already include ground point classification. Most publicly-available datasets have already been classified, especially data from the USGS. I often err on the side of trusting the host organization's standards for classification instead of having to make certain assumptions about the terrain via this routine.
laser ground [-h] [-o OUTPUT_FILE] [-odir output_directory] [--input-is-list]
[--keep-classification] [--compute-height] [--replace_z] [--fine]
[--extra-fine] [--coarse] [--extra-coarse] [--town] [--city] [--metro]
[--cores CORES] input_files [input_file(s ...]
positional arguments:
input_file(s) Input file(s)
optional arguments:
-h, --help show this help message and exit
-o OUTPUT_FILE, --output_file OUTPUT_FILE
Output file (default: None)
-odir output_directory, --output_directory output_directory
Output data directory. (default: None)
--input-is-list Use input file as a list of rasters to merge. (default: False)
--keep-classification
Keep original classes and only re-classify ground points. (default: False)
--compute-height Compute height above ground on the fly. (default: False)
--replace_z Overwrite Z values instead of storing height in a user data class. (default: False)
--fine Use in rugged terrain. (default: False)
--extra-fine Use in very rugged terrain. (default: False)
--coarse Use in flat terrain. (default: False)
--extra-coarse Use in very flat terrain. (default: False)
--town Use wide radius to find ground. (default: False)
--city Use wider radius to find ground. (default: False)
--metro Use widest radius to find ground. (default: False)
--cores CORES number of processing threads (default: 4)
