Zusammenfassung: | The utility model discloses a stereo map and a topography sand table made of natural soils including natural soils, a plurality of independent separating devices and a transparent shell to hold the natural soils. The separating device includes a bottom plate and a thin baffle. The edge curve of the bottom plate is the same with the map dividing line and the edge of the thin baffle along the bottom plate protrudes upwardly. All the separating devices are arranged together along the map dividing line. The natural soils are the unaffected soils from the area drawn on the map. The transparent shell covers the separating device above, and place names and a drawing line coinciding with the contour of the baffle, which represents the map separatrix, are drawn on the transparent shell. By using independent separating devices, a global map or a global topography sand table is formed by arranging all the separating devices together, and a local map or a local topography sand table is formed by arranging one separating device, which solves the inconvenience not only in making, bus also in moving or carrying the prior natural soil map. |
