Bing Maps Java SDK provides a Java wrapper to Microsoft's Bing Maps API. This allows developers to access the API's methods for searching for points of interest, getting driving directions, matching addresses to the map, and more. This project is currently open for adoption as the creator no longer has time to maintain it.
Google Maps API is the most popular tool for building location-based services. Now, the Google Maps Operations team is leveraging their experience to collaborate with Udacity and create a free course that teaches students how to integrate maps and location features into websites.
It's no secret that the Google Maps API is incredibly popular. Our directory lists over 2,100 Google Maps mashups, but that's obviously just a subset of all the sites powered by the mapping platform. And now we know how many sites that is. According to Google Developer Advocate Mano Marks, there are 350,000 websites incorporating Google Maps. And, of course, Google now has many other geographic APIs.
