How Do You Make A 3D Topographic Map?
A topographic map describes the terrain of the ground using contour lines. Contour lines connect points of similar elevation so that all points on a given contour line have the same elevation value. A three-dimensional topographic map, often called a raised relief map, allows easier visualization of the terrain features. However, in creating a three-dimensional topographic map the vertical exaggeration of the map is often increased. Vertical exaggeration refers to a difference between the vertical scale and horizontal scale of the map. This distortion allows terrain features to be accentuated. Select the terrain feature or section of a topographic map to be constructed three dimensionally. Find and count the contour lines of the selected terrain features. A copy of the topographic map will be needed for each contour line. Glue each copy of the section of the terrain map to be modeled onto cardboard. The thickness of the cardboard will determine the vertical exaggeration of the model. C
