NAME
v.in.pdal - Converts LAS LiDAR point clouds to a GRASS vector map with PDAL.
KEYWORDS
vector, import, LIDAR
SYNOPSIS
v.in.pdal
v.in.pdal --help
v.in.pdal [-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]
Flags:
- -w
-
Reproject to projects’s coordinate system if needed
Reprojects input dataset to the coordinate system of the GRASS project (by default only datasets with the matching coordinate system can be imported - -o
-
Override projection check (use current project’s CRS)
Assume that the dataset has the same coordinate reference system as the current project - -c
-
Do not automatically add unique ID as category to each point
Create only requested layers and categories - -r
-
Limit import to the current region - --overwrite
-
Allow output files to overwrite existing files - --help
-
Print usage summary - --verbose
-
Verbose module output - --quiet
-
Quiet module output - --ui
-
Force launching GUI dialog
Parameters:
- input=name [required]
-
LAS input file
LiDAR input files in LAS format (*.las or *.laz) - output=name [required]
-
Name for output vector map - id_layer=string
-
Layer number to store generated point ID as category
Set to 1 by default, use -c to not store it - return_layer=string
-
Layer number to store return information as category
Leave empty to not store it - class_layer=string
-
Layer number to store class number as category
Leave empty to not store it - rgb_layer=string
-
Layer number where RBG colors are stored as category
Leave empty to not store it - spatial=xmin,ymin,xmax,ymax
-
Import subregion only
Format: xmin,ymin,xmax,ymax - usually W,S,E,N - zrange=min,max
-
Filter range for z data (min,max) - return_filter=string
-
Only import points of selected return type
If not specified, all points are imported
Options: first, last, mid - class_filter=integer[,integer,...]
-
Only import points of selected class(es)
Input is comma separated integers. If not specified, all points are imported. - input_srs=string
-
Input dataset projection (WKT or EPSG, e.g. EPSG:4326)
Override input dataset coordinate system using EPSG code or WKT definition
DESCRIPTION
Imports a point cloud (e.g. from a LAS file) as vector points with the PDAL library. v.in.pdal supports the following filters:
- 2D region filter
- Z coordinates filter
- return filter
- class filter
EXAMPLES
Import only XYZ coordinates of points, limit the import to the
current computational region and reproject to the current project’s
coordinate reference system during the import:
v.in.pdal input=points.las output=points -c -r -w
