Espousing the wisdom implied in a famous metaphor, "dwarfs standing on the shoulders of giants," development of the VTA online transit-inventory application started out by examining samples in the online Google API demo gallery. Drawing on technology knowhow already embedded in those samples, a few Web applications particular for VTA's transit uses Figure 1 is a snapshot of the virtual tour, where the animation of the Google Earth view in the upper-left map panel is synchronized with that of the Google were developed. The first application is a virtual transit tour, which allows users to take a surrogate transit tour via the Internet through areas served by VTA. It was inspired by a "Driving Simulator" contained in the Google Earth API demo gallery to "simulate a scenic drive through your favorite neighborhood or familiarize yourself with an unknown route to a new destination." The sample Web page was redesigned, and the existing scripts were modified and customized to serve transit-map needs. The ensuing VTA Virtual Transit Tour application enables users to select a transit line, "travel" along the space traversed by the selected transit line, "hop" on/off a stop to visit attractions in the virtual neighborhood, speed up or slow down the tour, and toggle 3-D buildings. Figure 1. A map shows scenery captured on a virtual transit tour in the downtown along Bus Line 11 (Downtown Loop). Because it's area, many tall 3-D buildings are visible. Users can reset to restart the virtual tour, pause the tour to zoom in/out, tilt the view to a different angle, or toggle buildings on and off. M A Y 2 O 1 2 / 26 W W W . G E O P L A C E .
