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  operations  like  updating  header  information,  more  drastic changes, like
       removing points or altering values, will require las2las(1).

       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-separated  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)

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

       --keep-returns arg
              A list of return numbers to keep in the output file: --keep-returns 1 2 3

              Keep only valid points

       --keep-classes arg

       --drop-classes arg
              A   comma-separated   list   of   classifications  to  drop:  --drop-classes  1,7,8
              --drop-classes 2

       --keep-intensity arg
              Range in which to keep intensity.  The following expression  types  are  supported:
              --keep-intensity 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
