Install Anaconda, and create a conda environment with all the required software.
Open an Anaconda prompt, which looks like a Windows command prompt.
Type the following to create the environment called pointclouds:
conda config --add channels conda-forgeconda config --add channels riosconda create -n pointclouds rios scipy numba rios::pynninterp laspy lazrs-python
Download the scripts lazMerge.py and droneLasProcessing.py to your PC and navigate to that directory using the change directory command, such as:
cd C:\Users\Adrian\Documents\GitHub\point_clouds
Copy the LAZ files made by Pix4D (..\2_densification\point_cloud*.laz) to your PC
Run lazMerge.py to merge all the laz files into one.
'lazMerge.py --inDir C:\Users\Adrian\Documents\temp --outLaz C:\Users\Adrian\Documents\temp\merged.laz'
Run droneLasProcessing.py to create a digital surface model (DSM), digital elevation model (DEM), and canopy height model (CHM).
droneLasProcessing.py -i C:\Users\Adrian\Documents\temp\merged.laz -e 32754 -p conservation -o C:\Users\Adrian\Documents\temp
You can use two scripts in https://github.com/adrian-g-fisher/point_clouds to create the canopy height models (CHM).
