[GRASS-user] random points through multiple vector maps

[Dave Roberts]

Friends,

    I am trying to drop random points through two vector maps to 
establish the correspondence between them.  I couldn't figure out how to 
do that with v.random so I created a database table with 10,000 random 
points within the bounds of the region, and then used v.in.db to bring 
the points in as a vector map.  Then I tried v.what.vect using the 
random points on a vegetation map, but v.what.vect failed as noted below

v.what.vect map=rnd_points column=vmap_veg qmap=vmap qcolumn=vegtype
Finding nearest features...
  100%
Update vector attributes...
  100%
5049 categories - no nearest feature found
v.distance complete. 10000 records updated.

So 10,000 points were updated to NULL because no nearest feature was 
found.  Can somebody explain to me what went wrong or how to fix it?

OS: 3.12.6-1-ARCH
GRASS: grass70-svn

Thanks, Dave
