The Google Maps API introduced the concept of a mashup when it launched 5 years ago and is now used on over 350,000 websites. Looking to the future, it has been predicted that mobile maps usage will surpass desktop maps usage in the next couple of years. In 2008, the Google Maps API team began a detailed investigation into the API’s performance on mobile devices which concluded that the public interface made the significant refactoring necessary to improve map load time difficult, if not impossible. Consequently, Version 3 of the Maps API was born, designed first for mobile.

Maps API v3 launched in May 2009 and displays a map more than 2x faster than the previous version. Its post-load performance rivals native applications, while the time required for the Google team to launch new features is significantly less.

Susannah will share what her team has learned in developing this API as well as the techniques used to make drastic speed improvements.
