How To Draw Topographic Map

You need to plan this out so that you don t end up with a mess of lines.

How to draw topographic map. The difference in elevation between two adjacent contours is called the contour interval. From the maps you have aqcuired record elevation levels compass scale and any landmarks. Contours are to be placed every ten feet. This is typically given in the map legend.

To construct a topographic profile you need to find a line on a map that is interesting. In many cases this line is given to you often labeled something like a a or a b. All points along any one contour line are at the same elevation. The line should go through some part of the map that you are interested in so that you get useful information.

To draw a topological map you need to draw a symbol for each location and a bunch of lines connecting them together representing the routes between them. Visualize the file named claves inegi kmz located in topographic maps with google earth for instance click on the cell s corresponding to your area of interest. A contour line is level with respect to the earth s surface just like the top of a building foundation. Determine the location you want to map and gather maps of that location from local libraries or internet resources such as the link in the resources section.

Each contour line on a topographic map represents a ground elevation or vertical distance above a reference point such as sea level. Divide 300 feet by 3 to get one contour every 100 feet. Make sure students understand that contour maps though 2 dimensional use contour lines to show elevation above sea level. How to draw a topographic map.
