The nice people at Oracle implement all of their OpenGIS "contained within" geometry operators using bounding boxes only. This makes it impossible to select non-rectangular areas from a map.
Google has gotten me nowhere looking for a PDL geometric operator library that (ideally) works on OpenGIS format data (WKB, WKT) or at least implements a "contains" operator suitable for a point and polygon. I am not trying to plot anything, just get a boolean outcome for, say, which state contains a given lat+long or which hospital is closesest to a given point. Checking CPAN for PDL+GIS gives me PDL::GIS::Proj, which isn't about GIS and is also pretty much dead. Q: Any suggestions for an implemention for selecting which of a (largeish) list of polygons contain a given point? thanks -- Steven Lembark 3646 Flora Pl Workhorse Computing St Louis, MO 63110 [email protected] +1 888 359 3508 _______________________________________________ Perldl mailing list [email protected] http://mailman.jach.hawaii.edu/mailman/listinfo/perldl
