Abstract:
1. An antomated system for producing a hi-accuracy three-dimensional topographic map based on interpolated three-dimensional topographical data pertaining to an actual geographical area, comprising: topographic-data interpolation means for translating topographic data pertaining to the three-dimensional topography of an actual geographical area into a series of adjacent and parallel vertical cross- section planes and a series of adjacent two-dimensional contours wherein each plane of said series of cross-section planes incorporates one contour of said series of adjacent two-dimensional contours; wherein said topographic-data interpolation means is capable of forming said contours based on cartographic information related to said topographic map in addition to said topographic data; cutting means for cutting said hi-accuracy 3D topographical map based on said series of adjacent and parallel vertical cross-section planes and said series of adjacent two-dimensional contours; and a multi-axis driving device for driving the cutting means so as to move in response to each two-dimensional contour of the plurality of cross-section planes.
