Kyle, The 'magic' is actually done on the server side. First you get directions, and then, when you select one of the checkboxes, the function getPOIs() gets called. This function reads the polyline and sends the points to the server in a POST request. On the server, a primitive method is used. The Perl script builds a query consisting of a UNION of SQL statements similar to the radius search here: http://maps.forum.nu/gm_drag_polygon.html repeating the same SQL statement for each point in the polyline. There are smarter search methods that can be used, but MySQL, (on a cheap hosting solution), performs well, even with this huge and clumsy UNION statement. :-) -- Marcelo - http://maps.forum.nu -- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
