I have over 700 .las files in a lasd dataset. These files have around 2.8 billion LiDAR points in them with point spacings from 0.3 to 10. The geoprocessing tool LAS Points Statistics As Raster which I use to create a canopy height is taking over 24 hours to run. I know I can change the cell size to speed things along and I will do that. Right now cell size is 10 and that's worked well before with data from this vendor, but fewer files with around 400 million points. Does anyone know if combining the 700 files into several big files would speed performance? Has anyone processed this many points using LAS Points Statistics As Raster?
