I am trying to run the thin las tool, 2cm by 2cm, on a 7mil point cloud. I keep getting an out of memory error. is there any way to fix this, besides tiling the data?
Would need more details of your environment, LAS format, version of Pro. Exact steps to reproduce
The Thin Las tool gives me an out of memory error regardless of the settings. I'm on a windows 10 machine with 96GB of physical ram running ArcPro 2.7.1. The files are LAS 1.4 (format 6) and I have tiled them so that the largest laz file is only 75 kb. Even so, Thin LAS tool gives me an out of memory error within a minute despite never using much physical memory.
The Thin LAS tool is the only tool I have issues with and I get the same out of memory error doing 64-bit background geoprocessing in ArcMap (10.6.1). It doesn't seem to be an actual out of memory issue though because I can get the tool to run by switching to 32-bit foreground processing in ArcMap.
I am having this same issue when I choose Closest to Average Height for the Point Selection Method. I am also using 3D Thinning Dimension. After clicking run, the 000426: Out Of Memory.—ArcGIS Pro | Documentation error presented immediately.
Running ArcGIS Pro 2.6.1 and working with Pix4D photogrammetry-derived LAS files version 1.2.
