I have a pretty large polygon shapefile (almost 1.5 million buildings) that I want to display in Google Maps. As the KML would be far too big, I have to create tiles, right?
I don't want to host my own server, but just upload the tiles on my site. But how do I create the tiles for such a shapefile?
TileMill seems not working with such a large shapefile. It has to be Google Maps as I want to use the geolocation service that works best for the country the data is from.
