Hi all,
thanks for following up. Of course we need some smart way to deal with such huge
amounts of points (that's why I think we need a brand new provider). libLAS and PDAL
seem to overlap, and at least one developer is involved in both: does anybody know
why, and which one would be better to use?
All the best.
