Installation

lidar_platform

The best way to install lidar_platform is by cloning the repository from GitHub:

https://github.com/p-leroy/lidar_platform

After that, you have to add the directory containing lidar_platform to your PYTHONPATH. This step is dependent on the way you installed python. In many editors, you can set the PYTHONPATH without touching to the environment variables.

Once the path have been configured, the module or the tools can be imported in a classical manner, e.g.:

import lidar_platform
from lidar_platform import cc, las

Optional Python dependencies

Depending on your python installation, there are several ways to install modules. Sometimes, preferred ways are specified on the websites of the modules. So, do not hesitate to go and have a look at the installation recommendations, which can evolve with time.

For instance, with miniconda (or anaconda but the first one is preferred)

conda install -c conda-forge laspy

https://laspy.readthedocs.io/en/latest/installation.html

conda install -c conda-forge gdal

https://gdal.org/download.html

conda install -c conda-forge numpy, matplotlib, sklearn

You can also use pip, depending on your Python IDE.

pip install -r .\plateforme_lidar\requirements.txt

Third party tools

Paths to third party tools can be configured in lidar_platform.config.config.py.

Depending on what you need in the library, you will need to install third party tools:

  • To use lidar_platform.tools.cloudcompare and lidar_platform.cc, you will need CloudCompare. If CloudCompare is not installed in the standard directory (‘C:Program FilesCloudCompare’ on Windows), configure the path in lidar_platform.config.config.py. See more : http://www.cloudcompare.org

  • topo_bathymetry.poisson_reconstruction makes calls to the Adaptive Multigrid Solvers tools, especially `PoissonRecon.exe` See more: https://www.cs.jhu.edu/~misha/Code/PoissonRecon/Version13.8/

  • In case of failure during the gdal installation, it is possible to try to install it using OSGeo4W. You will have to add the root path to OSGEO4W (containing OSGeo4W.bat) to your environment variables. See more : https://trac.osgeo.org/osgeo4w
