I would assume that the setting of elevation of the location causes the trouble.
Maybe this will help you to set up the loaction properly:
Have a look at the code of r.in.srtm

and/or consult the article by Markus Neteler
Thanks for the various solutions.
The points are about 5 million per tile, and there are 23 tiles (about 115
million total). I'm not sure if this is considered a large amount of mass
input points.
Perhaps the table size is OK. I havent reached a size problem yet, but I

Hi,
I installed WINGRASS 63 RC6 and tried again v.rast.stats. Before running
it I chose a small region (only a bit more than 2 polygons). The
following error messages were printed:

Hi
It appears to me that this could be done if the raster maps supported
layers, AKA surfaces in my work group.

In the email topic you asked about scripting... Well, I have a friend
here that is not very computer literate but he needs to use some

It calculates a value for field of view, but I didn't notice an actual focal
