Acessing LiDAR FWF data using Python

EBA Project is collecting FWF LiDAR data. What does it mean? Basically, instead of 5 maximum returns per pulse we are receiving 80. The new generation of LiDAR ALS sensors can collect the "full wave" returned from the pulse, not only peaks. As it´s a bit new, there´s a lack of tools to access this full waveform information.

To help us with our analysis tasks, it was necessary to build something to help us to get FWF data corresponding to a discrete point.We receive this FWF data in two files: 1.3 format version LAS discrete file and a file with the same name and WDP extension, WDP which contains FWF data corresponding to discrete points inside the LAS file.

So, as we are using lidarutils class to access LAS data, I decided to extend it in a way it supports to get FWF data from corresponding to a discrete point.The result you can get on GitHub. The lasFWF.py contains the class that I created, and there´s a small program, testFWF.py, that shows how to use it.

Below is the result of testFWF.py program, Enjoy!
