Topographic maps and digital elevation models

1. Analyze a landscape (show your calculations)
   1. Basic map facts:
      1. Interval between index contours:
      2. Contour interval:
      3. The fractional scale is:
      4. Start with the fractional scale and convert the units on the ground to miles: The verbal scale is:
      5. The approximate height and width of the map estimated by counting the UTM

grids going N-S and E-W is …

(6) Calculating percentages can be tricky, so pay attention to how reasonable your

numbers are and what you think they mean. To start this problem, you know the

original scale is 1:24,000 and the scale of the map as published is 1:31,700 (from (4) above). This means that more of the U.S.G.S. map was squeezed onto a page than was originally possible. Thus, the map in Fig. 6.15 was shrunk by some amount.

By what factor (percent) was the map reduced?

1. Three tallest mountains:
2. Stream flow arrows: Add them on map. (1) (2) (3) (4)
