comment Geometry vs geography for line-to-polygon intersection
Woups, I just realized that I assumed my shapefiles to be WGS84, whereas they seem to be NAD83! I guess that explains my problem, as geographies work only with the latter, right? Shouldn't both systems be more or less equivalent though?

They both span the entire Quebec province, I updated my question with their infos.

comment What Lidar processing tools are available in Python?
It is not a direct answer to your question, but as I've been working on a Python software for the reconstruction of botanical trees from LIDAR-acquired point cloud data, perhaps the technology stack I've been using could give you some ideas. In particular, the visualization layer is built using VTK, which is very powerful.
