I recently learned about Google Mashups from my boyfriend who relayed class material from his MS in Management of IT program, and luckily with perfect timing in relation to current projects. Essentially, Google Mashups can be defined as a web page or application that combines data or functionality from two or more external sources, resulting in a new service. For example, a Mashup can be created by integrating Google Maps into a personal web page, combining web page information with map data.
Two weeks ago I launched the website for Monticello Wine Trail, in which I utilized Google Mashups. One of the most important aspects of the MWT website is the ability for visitors to view and learn about the smaller trail clusters of wineries, grouped by their proximity to one another. In the previous website, the trail information was provided on a static JPG image. By integrating Google Maps into the Flash site, website visitors are able to interact (zoom and pan) with the maps, providing an overall more interactive user experience and more detailed map information.
