Starts the GUI of LAStools with pre-populated input files.

Default: False

input LAS/LAZ file [points]

filter [string]

Specifies which points to use to construct the temporary TIN that is then rastered.

Default: —

step size / pixel size [number]

Specifies the size of the cells of the grid the TIN is rastered onto.

Default: 1.0

Attribute [string]

Specifies the attribute that is to be rastered.

Default: elevation

Product [string]

Default: actual values

use tile bounding box [boolean]

Specifies to limit the rastered area to the tile bounding box (only meaningful for input LAS/LAZ tiles that were created with lastile).

Default: —

Çıktılar¶

Output raster file [raster]: Specifies where the output raster is stored. Use image rasters like TIF, PNG, and JPG for false color, gray ramps, and hillshades. Use value rasters like TIF, BIL, IMG, ASC, DTM, FLT, XYZ, and CSV for actual values.

Tanım¶

This tool grids a selected attribute (e.g. elevation, intensity, classification, scan angle, ...) of a large point clouds with a user-defined step size onto raster using a particular method (e.g. min, max, average). For more info see the lasgrid page and its online README file.

verbose [boolean]

Generates more textual control output to the console.

Default: False

open LAStools GUI [boolean]

Starts the GUI of LAStools with pre-populated input files.

Default: False
