v.in.pdal(1grass)

Flags:

-w

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 cordinate system can be imported

-o

Override projection check (use current location’s projection)
Assume that the dataset has same projection as the current location

-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

-j

Classify and extract ground points
This assignes class 2 to the groud points

-k

Classify ground points

-h

Compute height for points as a difference from ground
This requires points to have class 2

-m

Use approximate algorithm in ground filter

--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

Layer number to store class number as category
Leave empty to not store it

rgb_layer=string

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
