Hi, I would love to see the addition of pgPointCloud added to the list of extensions that DigitalOcean offers for their PostgreSQL managed database.
You already have postgis (with raster support), pgrouting, PostGIS SFCGAL, and postgis topology. I think the final extension to make it a complete spatial database solution is to add pgpointcloud.
3D point clouds are becoming (if not already) extremely common (LiDAR - airborne and terrestrial - planes, satellites, drones, cars etc.) and this library provides efficient storage of these points as well as additional functions that are not available in the postgis extension allowing you to more efficiently work with these massive datasets.
At first it may appear that SFCGAL extension covers this functionality. They have some similarities when it comes to some functions. But What pgPointcloud really is doing as I mentioned is the storage efficiency of the massive datasets.
From the documentation
"LIDAR sensors quickly produce millions of points with large numbers of variables measured on each point. The challenge for a point cloud database extension is efficiently storing this data while allowing high fidelity access to the many variables stored."
Where SFCGAL is specifically dealing with the access and manipulation thru their functions of 2D and 3D data.
"SFCGAL is a C++ wrapper library around CGAL that provides advanced 2D and 3D functions."
Thank you for your time and consideration of pgPointcloud.
