PURPOSE:To display a solid figure such as a perspective on an external display means based on a topographic map of mesh form possible for stereoscopic processing by dividing an actually measured plane view into mesh and providing a mesh point data recording comprising mutual position of each mesh point and an altitude at each mesh point, a mesh topographic map generating means and a solid figure generating means. CONSTITUTION:Mesh is provided to a map of a raw stone mountain in which actually measured altitudes are displayed by contours, each mesh line in X and Y direction is crossed, for example, 23X23 sets of the same shaped frames are formed and 24X24 sets of mesh points being the cross points are provided at a prescribed interval. In adding the digging condition to the coordinate and the altitude data of the mesh points Pn, the coordinate and altitude data of the mesh points are measured after digging and based on the coordinate and altitude data after mining, a mesh form topographic map (plane view) or a solid figure such as a perspective are displayed externally. That is, the mesh topographic map generating means generates the mesh points comprising 23X23 frames based on the mesh point data and mesh distance. Then the mesh point having the altitude of highest level and a mesh point having the altitude of the lowest level are selected from the altitude of all the mesh points and displayed on the mesh. |
