Hi Darafei,

Thanks for the quick response. I'm not hugely familiar with the tools, but
quite possibly that is all that's needed.

Do you have some code, or link to a recipe or a good page to get started?

Thanks!
Bjoern

Is there anything in this that's not covered by importing OSM data using
osm2pgsql and then using a combination of PostGIS's ST_ClusterWithin and
ST_ConvexHull?
