But Google dropped a bombshell in October 2011 when its announced it would start charging the heaviest users of Google Maps and would eventually start inserting ads for other users (as it does for videos on YouTube). Google's price was quite high – $4 per thousand map views – which had popular map-based websites such as FourSquare scrambling to find cheaper alternatives rather than paying Google tens or even hundreds of thousands of dollars each month.
By June, Google realised it had priced its maps too high and was in danger of losing most of its potential paying customers, so it dropped the price by 88 per cent to 50 cents per thousand views. But the damage had been done. Other vendors and open-source solutions had already attracted attention as reasonable alternatives.
In fact, many of these alternatives have advantages over Google Maps beyond being cheaper (or free). Even if you are a small enough user of Google Maps that you wouldn't have to pay (you average less than 25,000 map views a day), it is worth your while to look at the alternatives.
What kind of map user are you?
Proprietary versus open APIs
In addition to Google Maps, there are a number of other proprietary APIs. Most proprietary APIs provide free or low-cost accounts to smaller users, as long as your maps are accessible to the public and not behind a password or other paywall.
Proprietary APIs are usually all-in-one solutions that include not just the API, but also basemaps and servers to serve map tiles to the API. This is both good (simpler to use) and bad (lack of flexibility). The main advantage of proprietary APIs is that they tend to include advanced features like real-time traffic, routing (directions), geocoding (translating addresses into locations), 3D buildings and 'bird's eye' views, street-level imagery, and information about businesses on the map.
On the other hand, some of the most popular alternatives to Google Maps API are open source. Mapping applications are incredibly diverse, and having access to the source makes it much easier to customise things to your needs.
Another advantage of open source is that you can mix and match components for your mapping solution. With Google Maps, Google controls all parts of the solution: the API, the maps, and the servers that serve these maps. Open-source map APIs allow you to pick from a large number of maps, or even create your own maps. You are also free to use your own servers, put your maps in the cloud, or outsource your map server needs.
Google Maps, of course, is still the 800-pound gorilla of mapping APIs. Google provides advanced features: powerful routing (including for walking, bicycling, and transit), Street View, 3D buildings, weather, and traffic information. Some of these features are unique to Google, so (depending on your application) you might have no choice but to use its API.
A big problem with Google is that you have little or no control. Google Maps comes with three base maps: street, satellite, and terrain. It is possible to use the Google Maps API with other maps but this is usually not a good idea because Google charges are based on API usage, even if you are not using its maps. If you aren't using Google's maps (or one of its other unique features), there is no reason to pay for them.
