Hello,
I have TLS (terrestrial) and ULS (UAV based) point cloud which I want to calculate Vertical Complexity Indices using forestR R package. But according to manual, input data must have XYZ coordinates and Vegetation Area Index (VAI) in order to run this package. Can anyone please let me know if there is any relatively simpler way to calculate VAI?
Thanks,
For VAI or LAI you will have to do ground truth and correlate to your LIDAR values. Another problem you may run into is R may not handle large point clouds so you may have chop up your data into smaller quads for processing.
You should have a look at the `lidR` package. It is providing a lot of functions dealing with your request. There is also a lot of support as the github Wiki of the developer lidR Wiki https://github.com/Jean-Romain/lidR/wiki
