Hello, I am a bit hesitant to recommend inserting LiDAR point clouds into a database (because I believe - for LiDAR or dense-matching points -- you should just only insert the shapefile outlines into a database and then run a las2las query on those spatially indexed (amd possibly resorted) LAS / LAZ files whose outlines overlap the queried area) as this has shown not to be very performant in a large study by TU Delft involving many different spatial databases ... but in some use cases it may make sense. The papers and relevant discussions are linked here:

Something like what Yuriv Czoli from developmentseed did will give you some pointers to get started: http://developmentseed.org/blog/2014/08/07/processing-lidar-point-cloud/ http://gist.github.com/YKCzoli/3605e014b8ed09a571e5 Regards, Martin On Thu, Jul 23, 2015 at 8:11 PM, Tim Sutton <[email protected]> wrote: > Hi > > > On 22 Jul 2015, at 09:39, Ziegler Stefan <[email protected]> wrote: > > Hi > > I just read in the changelog that there is some postgis pointcloud layers > support?
