There has been a lot of confusion with the premium big data plan, so this has been removed from new subscriptions. This is still available for those who are already subscribed to it. It supports up to 100K locations, but the latitude and longitude are required. There was a lot of confusion about this plan since people would subscribe to it hoping to map 30K+ addresses without the latitude and longitude. This takes too much time using the 50 address/second geo-coder. A request has been put in with Google to increase this speed.
We are very sorry for the confusion this has created. The premium plan with up to 15K locations per map is available.
