Plugin to generates a Digital Elevation Model (DEM) with the forest height, calculated from a classified LiDAR point cloud. This plugin uses the LasPy Library to process the point cloud (las format) and LasZip if the cloud is compressed (laz format)
Combines the ground returns and the first returns of the cloud of LiDAR classified data (ASPRS classification / *.laz, *.las formats). The result is a raster file (GeoTif).
The following image shows the heigths results of a forest area in grey scale.
You can classify with a color gradient by heigths, as follow.
To use this plugin you need SciPy, NumPy and LasPy:
To install LasPy Library (or others), you must launch the following lines at OSGEO Shell (OSGeo4W.bat at QGIS installation folder):
By default OSGeo console runs with Python 2, you need to configure the console to run with Python 3, so launch, from QGIS installation folder (Windows):
bin\py3_env.bat
bin\qt5_env.bat
python -m pip install numpy
python -m pip install scipy
python -m pip install laspy
LasPy documentation is avaible at: https://github.com/laspy/laspy
If the process option with the LasPy library is not activated once it has been installed, you must restart QGIS.
If you need to process compressed LiDAR data (*.laz format), the plugin uncompress automatically the point cloud with LasZip Library:
LasZip is LGPL License and you can found it at: https://laszip.org/
