+ las2txt (libLAS 1.6.0b3 with GeoTIFF 1.3.0 GDAL 1.8dev)
+ --------------------------------------------------------------------
+
+ las2txt options:
+ -h [ --help ] produce help message
+ -i [ --input ] arg input LAS file.
+ -o [ --output ] arg output text file. Use 'stdout' if you want it written
+ to the standard output stream
+ --parse arg The '--parse txyz' flag specifies how to format each
+ each line of the ASCII file. For example, 'txyzia'
+ means that the first number of each line should be the
+ gpstime, the next three numbers should be the x, y, and
+ z coordinate, the next number should be the intensity
+ and the next number should be the scan angle.
+
+ The supported entries are:
+ x - x coordinate as a double
+ y - y coordinate as a double
+ z - z coordinate as a double
+ X - x coordinate as unscaled integer
+ Y - y coordinate as unscaled integer
+ Z - z coordinate as unscaled integer
+ a - scan angle
+ i - intensity
+ n - number of returns for given pulse
+ r - number of this return
+ c - classification number
+ C - classification name
+ u - user data
+ p - point source ID
+ e - edge of flight line
+ d - direction of scan flag
+ R - red channel of RGB color
+ G - green channel of RGB color
+ B - blue channel of RGB color
+ M - vertex index number
+
+ --precision arg The number of decimal places to use for x,y,z,[t]
+ output.
+ --precision 7 7 3
+ --precision 3 3 4 6
+ If you don't specify any precision, las2txt uses the
+ implicit values defined by the header's scale value
+ (and a precision of 8 is used for any time values.)
+ --delimiter arg The character to use for delimiting fields in the
+ output.
+ --delimiter ","
+ --delimiter ""
+ --delimiter " "
+ --labels Print row of header labels
+ --header Print header information
+ -v [ --verbose ] Verbose message output
+ --xml Output as XML -- no formatting given by --parse is
+ respected in this case.
+ --stdout Output data to stdout
+
+ Filtering options:
+ -e [ --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 [ --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

+ The following expression types are supported:
+ --keep-scan-angle 0-100
+ --keep-scan-angle <100
