v.univar can also compute statistics on the distances between vector
geometries. There is no explanation in the manual what this should be good
for. Markus N, you wanted this feature many years ago, do you remember why?
I found this related ticket:
https://trac.osgeo.org/grass/ticket/942
Checking further, I found a personal wish email to MartinL from 2009.
AFAIR I was dealing with LiDAR point clouds of the Trentino back
then... and needed to know the average distance between points in
order to optimize raster binning (meanwhile I would probably use
r.in.xyz and count the points falling into each raster cell, then
r.univar on the resulting map).
However, to have the possibility to compute statistics on the
distances between vector (point) geometries makes sense to me in a
GIS.
Would this possibly be better done within v.distance ? Something like a
-s flag meaning "Output summary statistics of desired information" which
would take the info chosen in upload=, and possibly the -a flag and
calculated summary statistics ?
