1. A computer-implemented methodology for presenting virtual tours of user-defined paths in a geographic information system (GIS), the method comprising:

  • sending a plurality of user-defined locations to a server of the GIS;

    receiving a route from the server including the plurality of locations, the route being decimated into a plurality of points;

    providing at a first zoom level the route for display to a user; and

    in response to the user selecting the route, simulating a fly-through of the route from start to stop locations, including any intermediate locations, using a virtual camera in a three-dimensional model, the virtual camera having an azimuth and the azimuth determined at each of the plurality of points in the decimated route, thereby providing the user a virtual tour of the route.
