Hi Given a table of peaks with the fields id, name, elevation, geom I'd like to write a query which returns to me only those (randomly selected) peaks - i.e. peak buffers say with radius 5 kilometers - which dont 'overlap'. This is motivated by a visualization use case where label names should'nt overlap because of lack of visual space - as well as because of low network capacity between db and client!
Any ideas on how to solve this with a declarative SQL query? The only promising approach I found so far was is to define a subquery with ranked buffers and then to select some out of these... -S. _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
