You could use v.mkgrid to generate a grid. Then loop over all categories
in this grid (v.categories) and use v.overlay to intersect.
Thank you Markus, I had no problem in creating the grid with:
v.mkgrid --overwrite map=grid_vect grid=20,20 box=1,1
(only struck a small bug in the GUI which does not let you enter two values for
the grid (eg 20,20) so I had to enter the command in the command box).
But had no success at all using v.category and v.overlay to create individual
map tiles for each of the 400 tiles in the grid. I suspect I am not using
v.category properly but could not find an example that could help me.
My understanding is that for v.overlay to work, the b-input must be a single
tile, then the AND intersection will extract the a-input features for the area
under that tile. But I could not find a way to extract a single tile out of the
grid.
What am I missing?
Do I need to reduce the current region to the single tile before v.overlay and
then loop through all the tiles that way?
