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).

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-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

--drop-returns arg

Return numbers to drop. For example, --drop-returns 2 3 4 5

--valid_only

Keep only valid points

--keep-classes arg

A list of classifications to keep: --keep-classes 2 4 12 --keep-classes 2

--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 >413665.2336 --keep-time >=413665.2336

--drop-time arg

Range in which to drop time. The following expression types are supported: --drop-time <413666.2336 --drop-time >413665.2336 --drop-time >=413665.2336

--keep-scan-angle arg

Range in which to keep scan angle. The following expression types are supported: --keep-scan-angle 0-100 --keep-scan-angle <100 --keep-scan-angle <=100

--drop-scan-angle arg

Range in which to drop scan angle. The following expression types are supported: --drop-scan-angle <30 --drop-scan-angle >100 --drop-scan-angle >=100

--keep-color arg

Range in which to keep colors. Define colors as two 3-tuples (R,G,B-R,G,B): --keep-color '0,0,0-125,125,125'

--drop-color arg

Range in which to drop colors. Define colors as two 3-tuples (R,G,B-R,G,B): --drop-color '255,255,255-65536,65536,65536'
