Hi there,
as far as I know it's not on the roadmap.
Now, I'm far from an expert in LIDAR formats, but my impression is you wouldn't get much benefit from versioning LIDAR point clouds with geogig. Rationale being that, to the extent of my knowledge, two passes of LIDAR over the same area would produce two completely different datasets? it's not like points would lay on the exact same spot except if something changed at that very exact location. So, two point clouds would be totally different despite as a whole they'd represent roughly the same information?
In the context of vectorial datasets, which geogig is designed for, you can track change as it happens on certain features while others remain the same (e.g. editing through WFS/QGIS/etc). My impression is that model wouldn't fit for LIDAR data and every two versions would be completely different, meaning you'd have to store two completely different datasets, getting no real benefit out of geogig.
I might be wrong though, looking forward to your comments.
cheers,
Gabriel
