Could you specify the format of one piece of data exactly in text? Is it point, line, or polygon?

From my own You can aggregate points into lines, which then would give you a path, using a group by on a time criteria, for example. I would try to think in terms of the canonical geographical vector model: is it a point (zero dimension -- like a town in a small scale map) , a line (single dimension -- a road in the map), or a polygon (like a state boundary). How exactly are you collecting the data -- it might make it easier for all of us. _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
