A second distinguishing property is that the Earth's complex, nearly-spherical shape complicates efforts to specify exact positions on Earth's surface. One is that geographic data are necessarily generalized, and that generalization tends to vary with scale. What is the elevation there? Plot the location 345180mE 4022375mN with a dot or an X and label it 2 on the map.Chapter 1 outlined several of the distinguishing properties of geographic data. Plot the location 345740mE 4022940mN with a dot or an X and label it 1 on the map. Grand Canyon map Answer the questions using the Grand Canyon map below, elevations in feet Pe 023 X-X Cm Pe + 4022000 N 144000mE $45 346 Scale in Miles 0 0.5 1.0 What is the contour interval of the map? How would you describe topographic relief near the "Pe" labels? How would you describe topographic relief near the "Cm" label? Determine the scale of the map using the method provided in question #2 of the Grand Prismatic Spring exercise in the "Basic Science and Maps" lab worksheet. How can you tell which part is the crater? What is the contour interval on the map? What is the elevation in the middle/bottom of the crater? What is the high point elevation at SP Mountain? What are the elevations at these labelled points on the map: A: B: C: D: E: Determine the topographic gradient in feet/mile going from point A to the high point on SP Mountain show work (See p250 in Lab Book and slide 35 in "Topographic Maps" PowerPoint for explanations): SP Crater maps Answer these questions using the map below, elevations in feet 34 SP SP Crater 2001 Mountain Back Tank Waten 4D 4VD N Scale in Miles 0 0.25 0.5 Shim Tonk Both SP Mountain and S P Crater are labeled on the topographic map above.

Science and Map Coordinates lab worksheet (either "cross multiply" or "map scale"). What is the contour interval (change in elevation between each contour line) of the map? What is the high elevation on the map? How do you know? What is the low elevation on the map? How do you know? Give the elevation of each point on the map (in feet): G F E D H 1 А J B с F.
