Ok, with a little help from Bradley Chambers on the PDAL*mailing list, we are back in business. If we want to filter our newly calculated heights into a new PDAL output, we can do that easily, say all points 100-500 above ground level:
pdal translate 54001640PAN_heightasz.bpf 54001640PAN_heightasz_gt100.bpf -f range --filters.range.limits="Height[100:500]"A little sanity check to see if we are getting appropriate values:
pdal info --stats 54001640PAN_heightasz_gt100.bpf --dimensions "Height"{ "filename": "54001640PAN_heightasz_gt100.bpf", "pdal_version": "1.1.0 (git-version: 64c722)", "stats": { "statistic": [ { "average": 105.8738232, "count": 179909, "maximum": 194.5800018, "minimum": 100, "name": "Height", "position": 0 } ] }}Ok, now I want to view this. I could convert to a *.laz file and view it with plas.io (as long as I use Chrome as my browser).
I have to switch back to docker, ’cause that’s where I have PDAL built with laszip:
docker run -v /home/gisuser/test:/data pdal/master pdal translate //data/54001640PAN_heightasz_gt100.bpf //data/54001640PAN_heightasz_gt100.lazAnd now I can view in plas.io:
