las2iso¶

Descripción¶

This tool turns point clouds (up to 20 million per file) into iso-contour lines by creating a temporary Delaunay triangulation on which the contours are then traced. For more info see the las2iso page and its online README file.

Parámetros¶

verbose [boolean]

Generates more textual control output to the console.

Por defecto:Falso

open LAStools GUI [boolean]

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

Por defecto:Falso

input LAS/LAZ file [points]

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

smooth [integer]

Specifies if and with how many passes the temporary TIN should be smoothed.

Predeterminado: 0

extraer isolínea con un espaciado de [number]

Specifies spacing at which iso-contour lines are getting extracted.

Predeterminado: 10.0

clean isolines shorter than [number]

Omits iso-contour lines that are shorter than the specified length.

Predeterminado: 0.0

simplify segments shorter than [number]

Rudimentary simplification of iso-contour line segments that are shorter than the specified length.

Predeterminado: 0.0

simplify segment pairs with area less than [number]

Rudimentary simplification of bumps formed by consecutive line segments whose area is smaller than the specified size.

Predeterminado: 0.0

parámetro(s) adicional(es) de la línea de órdenes [string]

Specifies other command-line switches not available via this menu but known to the (advanced) LAStools user.

Por defecto: —

Salidas¶

Archivo raster de salida [raster]

Specifies where the output vector is stored. Use SHP or WKT output files. If your input LiDAR file is in geographic coordinates (long/lat) or has geo-referencing information (but only then) you can also create a KML output file.
