Abstract

A method for presenting a perspective view of a real urban environment, augmented with associated geo-coded content, and presented on a display of a terminal device. The method comprises the steps of: connecting the terminal device to a server via a network; communicating user identification, user present-position information and at least one user command, from the terminal device to the server; processing a high-fidelity, large-scale, three-dimensional (3D) model of an urban environment, and associated geo-coded content by the server; communicating the 3D model and associated geo-coded content from said server to said terminal device, and processing said data layers and said associated geo-coded content, in the terminal device to form a perspective view of the real urban environment augmented with the associated geo-coded content. The 3D model comprises a data layer of 3D building models; a data layer of terrain skin model; and a data layer of 3D street-level-culture models. The processed data layers and the associated geo-coded content correspond to the user present-position, the user identification information, and the user command.
