Scrape CartoDB Polygon Data Google Maps

This google map [login to view URL] is displaying a large amount of polygons. Viewing the source you can see they are using a service called CartoDB. Zooming in on the map you will see that there are alot of polygons. If the map were using a standard GeoJSON file as in the demo [login to view URL] then my guess is that GeoJSON file would be much too large for a user to load each time they look at the map. This is probably why they are using CartoDB. I have a fealing that CartoDB has converted the GeoJSON/Polygon data into images that are overlayed on the google map, which is probably much quicker. Markers/Pins are not required to be extracted as I believe this would increase load time on the final map. A. Find out how CartoDB is storing and displaying the polygons. Is it GeoJSON or are they Image files overlayed on top of Google Maps. B. Extract the colored polygons in the same format as used by CartoDB to local storage. C. Display the polygons on a Google Map. D. B&C needs to be scripted to extract data from the Original Map [login to view URL] so I can setup a daily CRON job to keep my map updated with the original.
