21   Flags:
22       -w
23           Reproject to location’s coordinate system if needed
24           Reprojects input dataset to the coordinate system of the GRASS  lo‐
25           cation (by default only datasets with the matching cordinate system
26           can be imported
27
28       -o
29           Override projection check (use current location’s projection)
30           Assume that the dataset has same projection as the current location
31
32       -c
33           Do not automatically add unique ID as category to each point
34           Create only requested layers and categories
35
36       -r
37           Limit import to the current region
38
39       --overwrite
40           Allow output files to overwrite existing files
41
42       --help
43           Print usage summary
44
45       --verbose
46           Verbose module output
47
48       --quiet
49           Quiet module output
50
51       --ui
52           Force launching GUI dialog
53

60           Name for output vector map
61
62       id_layer=string
63           Layer number to store generated point ID as category
64           Set to 1 by default, use -c to not store it
65
66       return_layer=string
67           Layer number to store return information as category
68           Leave empty to not store it

77
78       spatial=xmin,ymin,xmax,ymax
79           Import subregion only
80           Format: xmin,ymin,xmax,ymax - usually W,S,E,N

88           Options: first, last, mid
89
90       class_filter=integer[,integer,...]
91           Only import points of selected class(es)
92           Input is comma separated integers. If not specified, all points are
93           imported.
94
95       input_srs=string
96           Input dataset projection (WKT or EPSG, e.g. EPSG:4326)

DESCRIPTION

101       Imports a point cloud (e.g. from a LAS file) as vector points with  the
102       PDAL library.  v.in.pdal supports the following filters:
103
104           •   2D region filter
105
106           •   Z coordinates filter
107
108           •   return filter
109
110           •   class filter
111

EXAMPLES

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