In 2017 I started a side activity (freelancer) as a consultant and trainer for the subjects I specialized during my PhD thesis. (see my CV/Resume and skills for more details)
In fact, the “consulting” part is not really new, as I have been helping people on open source PostGis mailing list for several years. Moreover, consulting is quite similar in spirit to classical inter-colleague collaboration in a research lab.
As for the “training” part, I recently gave a 3-day training specialized on point cloud. This very practical session was about Open source software for visualization and processing of point clouds. The main open source software used are CloudCompare, Meshlab, the PCL, and PDAL.
The detailed program of the training is here in French )
