How Do You Make A 3D Model From A Topographic Map?
When a flat topographical map is transformed into a 3D model of the area, geography and map skills become real, understandable concepts. Select a topographical map that you wish to turn into a 3D model. The more lines on a map, the harder it will be to create. Start simple. Understand what you are looking at: A topographic map shows elevation. Each “circle” (these are never perfect circles – usually very squiggly) indicates how high above sea level the area is. These circles are called contour lines. As contour lines get smaller and closer together, this symbolizes the land getting higher and steeper. The smallest contour line is the highest point on the map. Cut out the biggest circle, or contour line. There will be smaller lines in the middle. Ignore those for now. Trace your cut-out on cardboard and cut the cardboard out. This is the base of your 3D model. Repeat this procedure for the rest of the lines on the topographic map. Cut out each contour line circle, trace onto cardboard,
