Hi, I have a shapefile of state senate districts in Texas. We've built two sets of precinct level boundaries, using different methods, which we can call A and B. Furthermore, I have a membership list that has long/lat for each member. Here's what I'd really like to do: I want to see if the pairwise error rate is proportional to the shared boundary length.
How would I go about writing the queries to do this? Let's assume that the tables in question are: public.t_ssd, public.t_precinct_a and public.t_precinct_b, public.t_membership_list I've copied a buddy of mine on the email who's also interested in the result, so please do include him when you reply! Thanks! -dx _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
