If they plan to display *every* parcel as a distinct element, yeah, but as I understood it, they just want the properties they are selling to "stand out" on the map. You wouldn't be using GPS to *outline* every single property, nor even the properties in question -- The "outline" for any object at any level of a map is hand-drawn by a human for the given map. The GPS data tells you what's on the map and "where" the "dot" belongs, but doesn't attempt to model the entire planet. Modeling that much data for such a "small" project (compared to e.g. MapQuest) would be silly. This is "do-able" for a reasonable number of properties, but "impossible" for doing every property when you want to scale up to something like MapQuest size. They're solving different problems, and I don't think the best solution for both is the same. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
