Press release: “Today Google officially released a new feature of Google Maps that enables users to layer valuable third-party information directly on Google Maps with a single click and to save these customized maps to their personal library. These mini-applications, called Mapplets, make it possible for users to view and layer maps containing information such as real estate listings, jogging trails, events and photos…These tools are built using the Google Mapplets platform, which enables any developer to create mini map applications that overlay their content on Google Maps and showcase their services to millions of Google users.
