A system and method for providing a street route to a user. A server communicates with a user and a routing engine. Database includes spherical photographic images, street vectors, and parcel coordinates. User gives start and end addresses and requests a route. Start and end addresses are sent to routing engine which responds with parsed start and end addresses and route therebetween. Exact start and end locations are calculated with reference to street vectors and parcel coordinates in the database. Spherical photographic images corresponding with calculated start and end locations, and display points calculated with reference to maneuver points provided by routing engine, are retrieved. Rectangular images are created corresponding with start and end locations and display points. Graphical navigation aids are superimposed on images. Optionally, advertising is inserted at appropriate points on images. A report is provided to the user.
