Keywords: v.surf.rst Cc:
CPU: x86-64 Platform: Linux

Description

running v.surf.rst on grass 70svn on an AMD vishera 8 core 3.5 Ghz cpu with 8 GB RAM . Fired it up with the defaults for a section of Western North Carolina with 77 million bare earth points to create a 23 million cell 20 ft resolution grid. I will attempt to attach screenshots of completed grid and grid complete with v.surf.bspline. Region was set to output v.surf.bspline raster.
