The Google Street Team brought the Google Trike to on Monday and Tuesday as the result of a national contest.
Google asked its users to submit nominations for pedestrian-only locations they'd most like to see on its popular map feature in several categories, including theme parks and zoos. More than 15,000 voters said they wanted a virtual tour of the Detroit Zoo, beating out the San Diego Zoo and Universal Studios in Florida, among others.
The Google Street Trike is a three-wheeled pedi-cab equipped with digital cameras. Google technicians spent two days collecting digital images of the zoo's award-winning habitats and attractions, both indoors and out.
The imagery will be featured on Google Maps via Street View, which allows users to view panoramic, interactive street-level imagery of parks and trials, landmarks, university campuses and sport venues around the world.
