Multi-Scale Visualization for GIS Road Features in Mobile Applications System

Multi-scale visualization plays a critical role in route planning and road guiding operation in a mobile applications system. The existing two approaches used for general spatial visualization present their own drawbacks and disadvantages. In this context, in order to display these road representations with different detail levels at a successive and smooth transformation order, this paper is devoted to a combined approach, also named `object interpolation', where some feature classes are stored as level of detail (LoD) in a multi-scale database, while others are generated in real-time from the base dataset. The interpolation principle, overall framework and technical flow are put forward. Then, the object interpolation function is defined and described, which reflects the inheritable and transferable characteristics of quantitative, structural, geometrical, semantic, topological and attribute related information among multi-scale representation objects. At last, a case in point is given to indicate that the new method is a guarantee of objective selection of the road objects at middle scale.
