The launch of Google Maps (, the search engine’s online geographical mapping application, ushered in a revolution in visualizing location-based data. Not only do Google Maps’ built-in features help you find establishments, addresses, and driving directions, but Google opened its maps interface to third-party developers for their own use. The result is a host of Google Maps mashups, which plot sets of data onto web-based maps.


These map mashups are an incredible way to see geographical information in a new manner. This hack points you to several of the best mashups that can help you adjust your commute home from work for traffic, decide where to live, help you find a nearby used car for sale, and figure out how far your jog across the bridge this morning really was.

In addition to plotting various sets of data, Google Maps’ open API enables a new breed of user-generated maps to flourish. Several of those applications enable users — or groups of users — to create annotated maps with photos and video. For example, a knitting group may publish a map of all the best yarn stores across the country. Or someone who just moved to Seattle may want to share a map with photos and videos of new favorite spots. These things are all possible with this new breed of web application.
