NAME

       lasinfo - display LAS file details

SYNOPSIS

       lasinfo [-h | -i arg [-v] [--no-vlrs] [--no-schema] [--no-check] [--xml] [-p arg] [Filtering options] ]

DESCRIPTION

       lasinfo displays LAS file details with optional output filters.  While lasinfo can do a few simple opera‐
       tions  like  updating  header information, more drastic changes, like removing points or altering values,
       will require las2las(1).

OPTIONS

       lasinfo options:

       -h, --help
              produce help message

       -i arg, --input arg
              input LAS file

       -v, --verbose
              Verbose message output

       --no-vlrs
              Don't show VLRs

       --no-schema
              Don't show schema

       --no-check
              Don't scan points

       --xml  Output as XML

       -p arg, --point arg
              Display a point with a given id.  --point 44

       Filtering options:

       -e arg, --extent arg
              Extent window that points must fall within to keep.  Use a comma-separated or quoted,  space-sepa‐
              rated  list,  for  example,  -e minx, miny, maxx, maxy or -e minx, miny, minz, maxx, maxy, maxz -e
              "minx miny minz maxx maxy maxz"

       --minx arg
              Extent must be greater than or equal to minx to be kept.  --minx 1234.0

       --miny arg
              Extent must be greater than or equal to miny to be kept.  --miny 5678.0

       --minz arg
              Extent must be greater than or equal to minz to be kept.  If maxx and maxy are set  but  not  minz
              *and maxz, all z values are kept.  --minz 0.0

       --maxx arg
              Extent must be less than or equal to maxx to be kept.  --maxx 1234.0

       --maxy arg
              Extent must be less than or equal to maxy to be kept.  --maxy 5678.0

       --maxz arg
              Extent  must be less than or equal to maxz to be kept.  If maxx and maxy are set but not maxz *and
              minz, all z values are kept.  --maxz 10.0

       -t arg, --thin arg (=0)
              Simple decimation-style thinning.  Thin the file by removing every t'th point from the file.

       --last_return_only
              Keep last returns (cannot be used with --first_return_only)

       --keep-intensity arg

              0-100 --keep-intensity <200 --keep-intensity >400 --keep-intensity >=200

       --drop-intensity arg
              Range  in which to drop intensity.  The following expression types are supported: --drop-intensity
              <200 --drop-intensity >400 --drop-intensity >=200

       --keep-time arg
              Range in  which  to  keep  time.   The  following  expression  types  are  supported:  --keep-time
              413665.2336-414092.8462    --keep-time    <414094.8462    --keep-time   >413665.2336   --keep-time
