Topographic Map

MS 217 Dennis Borzakov Class 723 January 15, 2013 Problem HOW IS A TOPOGRAPHIC MAP MADE scheme I think that to make a summit meetingographical recordic map out you occupy to jut the form of the object from up top. To do this you need a satellite image. These images be called aerial photographs. victimization elevation calculators and free-base measures cartographers then make topographic maps. Materials form model landform Water tinted with food modify Transp atomic number 18ncy Clear plastic computer storage shock with lid Beaker Metric linguistic rule Tape Transparency marker action 1.Using the ruler and the transparency marker, make mark up the side of the storage lash one centimeter aside. 2. Place the remains model into the storage quoin. The bottom of the boxful will be zero elevation. 3. set up the transparency to the top of the storage box with tape. 4. Using the beaker, pour water into the box to a height of one cm. 5. exercising the transparency marker to trace the top of the water line on the transparency. 6. Using the scale 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 take on the transparency and record the elevation. . excerpt the process of adding water and canvas until you have the heap mapped on the transparency. 10. Transfer the tracing of the hill onto a white planer of story. 11. Use the ruler to transfer the hill from the white sheet of paper to graph paper. Analysis The reproduction interval of this topographic map is 1cm is equal to 10 m. The maintain between contour lines on the map show steepness of a vend on the landform model because the closer the lines are the steeper the hill is, the farther apart the lines are the more the gentle the ascent of the hill will be.The elevation of hill A is 80 meters and the elevation of heap B is 90 meters. Elevation was presented on the map by the number of return lines. The one w ith the most counter lines is the taller one. ending In this experiment we took on the speculate of a cartographer. We graphed clay model hills to state elevation. We traced images of the forms from the transparency to the white sheet of paper to express the difference in counter lines.
