NAME - Converts LAS LiDAR point clouds to a GRASS vector map with PDAL.


vector, import, LIDAR

SYNOPSIS --help [-wocr] input=name output=name [id_layer=string] [return_layer=string] [class_layer=string] [rgb_layer=string] [spatial=xmin,ymin,xmax,ymax] [zrange=min,max] [return_filter=string] [class_filter=integer[,integer,...]] [input_srs=string] [--overwrite] [--help] [--verbose] [--quiet] [--ui]


Reproject to location's coordinate system if needed
Reprojects input dataset to the coordinate system of the GRASS location (by default only datasets with the matching coordinate system can be imported
Override projection check (use current location's projection)
Assume that the dataset has same projection as the current location
Do not automatically add unique ID as category to each point
Create only requested layers and categories
Limit import to the current region
Allow output files to overwrite existing files
Print usage summary
Verbose module output
Quiet module output
Force launching GUI dialog


input=name [required]
LAS input file
LiDAR input files in LAS format (*.las or *.laz)
output=name [required]
Name for output vector map
Layer number to store generated point ID as category
Set to 1 by default, use -c to not store it
Layer number to store return information as category
Leave empty to not store it
Layer number to store class number as category
Leave empty to not store it
Layer number where RBG colors are stored as category
Leave empty to not store it
Import subregion only
Format: xmin,ymin,xmax,ymax - usually W,S,E,N
Filter range for z data (min,max)
Only import points of selected return type
If not specified, all points are imported
Options: first, last, mid
Only import points of selected class(es)
Input is comma separated integers. If not specified, all points are imported.
Input dataset projection (WKT or EPSG, e.g. EPSG:4326)
Override input dataset coordinate system using EPSG code or WKT definition

Table of contents


Imports a point cloud (e.g. from a LAS file) as vector points with the PDAL library. supports the following filters:


Import only XYZ coordinates of points, limit the import to the current computational region and reproject to the Location projection during the import: input=points.las output=points -c -r -w
