[GRASS-dev] Spatial clustering of vector objects?

[Markus Neteler]

Hi,

in order to parallelize some heavy computation I was wondering how to
do spatial clustering of vector objects, i.e. building footprints
(vector polygons).

I have to perform zonal statistics on thousands of buildings and would
like to split them up into "tiles" and then run the computation in
parallel for each tile.

The examples in v.cluster look somehow promising
https://grass.osgeo.org/grass72/manuals/v.cluster.html

but in the best case each "tile" would contain a similar amount of
buildings in order to balance the computation across the CPUs.

Any idea?

thanks,
Markus
