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.


verbose [boolean]

Generates more textual control output to the console.

Vorgabe: False

LAStools-GUI öffnen [boolean]

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

Vorgabe: False

LAS/LAZ-Eingabedatei [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.

Vorgabe: 0

Extrahiere Isolinie mit einem Abstand von [number]

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

Vorgabe: 10.0

Iso-Linien vereinfachen kürzer als [number]

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

Vorgabe: 0.0

Iso-Linien vereinfachen kürzer als [number]

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

Vorgabe: 0.0

Segmentpaare vereinfachen mit Fläche kleiner als [number]

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

Vorgabe: 0.0

Weitere(r) Kommandozeilenparameter [string]

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



Ausgabevektordatei [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.
