Antonio,
This sounds interesting, but I have not found Intensity to be a calibrated metric. It can vary from collection to collection.

Subject: [EXTERNAL] [pdal] RGB colors by intesity
Hello,
I am new with PDAL. I have been using the last three years LAStools and I have now a problem that I don't know how to solve with LAStools, so I am exploring other tools/libraries/software.
I want to RGB colourise a point cloud but using Intensity values of each point to blend the colours.
So, for example, let's say that I have the vegetation RGB colourise monochromatically like R0 G255 B0. My goal is to multiply the RGB values of each point by the intensity value of each point (I have already set the intensity values between 0 and 255). So doing it, I will get a brighter green where the intensity is higher and a darker green where intensity is lower. My RGB will be then scaled up to 16 bit which is not a problem for me.
Does it sound possible to you using PDAL??
Thank you very much
Kind regards
Antonio Javier Soto Molina
