Developers working with Google's next generation of its popular mapping API (our Google Maps API Profile) will be pleased to learn that some new features have been added to the API. Since its initial release a little less than a year ago, v3 of the Google Maps API has steadily been growing in terms of features and functionality. The latest addition of features are three new "layer classes" that make it dead simple to add KML (or GeoRSS), traffic, or bike routes as overlays on a Google Map.
Earlier this year, Google requested map data from the Korean government. In response, Korean tech companies Naver and Kakao have increased free limits to their respective maps APIs beyond what Google offers. The government is expected to respond next month but the competition has already started.
In October Google announced the cost for Google Maps if you use above 25,000 map loads per day. Many developers balked at paying for a service that had been free for several years, though it affected fewer than 1% of developers using the Google Maps API. Now the search giant is lowering the cost from $4-8 CPM to a fixed price of $0.50 per 1,000 map views. It will also start enforcing the price, though the company says this process is not automated.
