3D Visual Intergrated System for Planning Economical Routes Using Geographic Data


Naotugu NOZUE, Takao SHIROTORI
A visual and interactive economical route planning system has been developed by coupling the image data with the altitude data. Available image data are not only remote sensing data but also nature-of-soil map and fault map. Routes can be defined throngh image maps on CRT displaying both contour and selected geographical information. As the cross section of a selected route can be displayed at the same time, gradients of route are decided easily. Furthermore, the system can calculate the total length of sections having the same depth from the surface and show a bird's-eye view of related area with instruction of routes from a demanded viewpoint. Based on these functions, a route plan can be easily drawn up that fits the economic and environmental criteria.
