Topographic Map

MS 217 Dennis Borzakov Class 723 January 15, 2013 Problem HOW IS A topo representic MAP MADE Hypothesis I think that to make a topographic map you have to see the form of the object from up top. To do this you need a satellite image. These images are called aerial photographs. employ bringing up calculators and ground measures cartographers then make topographic maps. Materials Clay form landform Water tinted with food coloring Transparency Clear plastic shop box with lid Beaker Metric ruler Tape Transparency crisscross Procedure 1.Using the ruler and the transparency score, make marks up the look of the storage box one centimeter apart. 2. Place the clay sit into the storage box. The bottom of the box will be zero elevation. 3. take prisoner the transparency to the top of the storage box with tape. 4. Using the beaker, pour irrigate into the box to a height of one cm. 5. hold the transparency marker to trace the top of the water line on the transparency. 6. Using the eggshell 1cm=10m, mark the elevation on the line. 7. Remove the transparency and add water until a depth of 2cm is reached. 8. Map this level on the transparency and place down the elevation. . Repeat the process of adding water and tracing until you have the hill mapped on the transparency. 10. Transfer the tracing of the hill onto a white sheet of paper. 11. Use the ruler to transfer the hill from the white sheet of paper to graph paper. Analysis The counter interval of this topographic map is 1cm is equal to 10 m. The distance between contour lines on the map show steepness of a slope on the landform model because the closer the lines are the sharp the hill is, the farther apart the lines are the more the gentle the wage increase of the hill will be.The elevation of Hill A is 80 meters and the elevation of Hill B is 90 meters. Elevation was presented on the map by the number of counter lines. The one with the most counter lines is the taller one. Conclusion In this exper iment we took on the job of a cartographer. We graphed clay model hills to pull elevation. We traced images of the forms from the transparency to the white sheet of paper to express the difference in counter lines.
