Topographic Map Exercise: Please Work In Pairs-Do Not Write on Topographic Maps Some of the most important information on a topographic map isn't on the map itself, but on the Map Collar the area between the neatline and edge of the paper. Select a topographic map to answer the following questions Each topographic map, or quadrangle, is assigned a name. This name is found in the upper- right corner in large print. What is the name for the map provided? 13. Notice the small reference map in the lower right margin of the map. There you will find a small black box denoting the location of this quad. In what part of the state is the area located? What is the name of the map that adjoins the western edge of the quad? 15, What is the name of the map that adjoins the southeastern edge of the quad? 16. There is detailed information located on the bottom of topographic maps. When was the area first and last surveyed? Also, when was this particular map published? 17. First Surveyed (lower left corner) 18. Last Surveyed/Field Checked (lower left corner) 19. Published (lower right corner) (this date is printed not a stamp) Another useful piece of information in the map collar is the north arrow, which displays three separate north values. The line with the star represents geographic, or true, north. GN stands for grid north, which follows the UTM coordinate system, and MN stands for magnetic north which points toward the North Pole of Earth's magnetic field. What is the magnetic declination of the area shown on your map? 20. Patrich Physical Geography Lab 16Explanation / Answer
