Abstract : City street environments are highly populated with 3D building data and associated information. Therefore, a suitable datarepresentation scheme is needed for effectively representing relevant information to an urban navigator. The focus of this paper is topropose a design methodology for providing users with just adequate information that helps them to satisfy their purpose of visiting aparticular building in a city street. In addition, we suggest a mechanism that renders the requisite information with selective levels ofdetail by emphasizing the regions of interest and diminishing the details of less important regions, depending on the users intention.Preliminary tests of the proposed data scheme on a set of real street building data and its evaluations show the feasibility of our approachto extend to large scale mobile applications.
