The database to generate that page contains polylines for all the zip codes, and selects properties by zip code.
There's no fancy code that draws the polyline around the displayed markers, there'll be an SQL query on their server that says something like SELECT * FROM Properties WHERE Zipcode = 90061, and the markers will be inside the 90061 zip code polyline simply the properties have 90061 as their zip code. -- Mike Williams http://econym.org.uk/gmap --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
