Quova's is a geolocation service, went free last November. The company has revamped its developer portal and added a few awesome new features to the Quova API. The company also added JSON as a response format, as so many other APIs have lately. Unlike the APIs ditching XML, Quova is keeping the XML format and expanding developer options. Also, the company added a developer forum and app gallery to its portal, to encourage community around its API.
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.
