     a) 5 centimeters on the map is equivalent to how many meters on the ground?
         5 centimeters on the map is equivalent to 1,200 meters on the ground.

     b) 5 inches on the map is equivalent to how many miles on the ground?
         5 inches on the map is equivalent to about 1.89 miles on the ground.

     c) one mile on the ground is equivalent to how many inches on the map?
         One mile on the ground is equivalent to 2.64 inches on the map.

     d) three kilometers on the ground is equivalent to how many centimeters on the map?
         Three kilometers on the ground is equivalent to 12.5 centimeters.

7. What is the contour interval on your map?
The contour interval is 20 feet.

8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:
      a) the Public Affairs Building
          34º04'23" N, 118º26'18" W
          34.07 N, 118.44 W

      b) the tip of Santa Monica Pier
          34º00'35" N, 118º29'58" W

          560 ft, 170.69 meters

      b) Woodlawn Cemetery
          140 ft, 42.67 meters

      The UTM zone is Zone 11.

11. What are the UTM coordinates for the lower left corner of your map?
      The UTM coordinates are (362000m E, 3763000m N)

12. How many square meters are contained within each cell (square) of the UTM gridlines?
      Each cell is 1,000,000 square meters.

13. Obtain elevation measurements, from west to east along the UTM northing 3771000, where the eastings of the UTM grid intersect the northing.  Create an elevation profile using these measurements in Excel (hint: create a line chart).  Figure out how to label the elevation values to the two measurements on campus.  Insert your elevation profile as a graphic in your blog.

The bold numbers represent the UTM northing 3771000 elevations at the UCLA campus.

14. What is the magnetic declination of the map?
The magnetic declination is 14º.

15. In which direction does water flow in the intermittent stream between the 405 freeway and Stone Canyon Reservoir?
The water flows south.

16. Crop out (i.e., cut and paste) UCLA from the map and include it as a graphic on your blog.
