LAStools algorithm provider

LAStools is a collection of highly efficient, multicore command line tools for LiDAR data processing.

blast2dem

Description

This tool can turn billions of points with via seamless Delaunay triangulation implemented using streaming into large elevation, intensity, or RGB rasters. For more info see the blast2dem page and its online README file.

Parameters

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

input LAS/LAZ file [points]
The file containing the points to be rastered in LAS/LAZ format.
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]

Outputs

Output raster file [raster]
