Abstract :
The functions of successive display and intelligent zoom among objects at different scales have not been developed in existing multi-scale navigation electronic map software system. So, taken the multi-scale and multi-media characteristics into consideration, this paper discusses the design and development strategies of multi-scale navigation electronic map. The total structure is built from the view of software engineer, and the key techniques based on interpolation method are proposed in details for intelligent zoom of multi-scale road map. At last, a case in point is given to build a convenient and visual spatial information services platform for route design, route guide and route display.
