1. What is the name of the quadrangle?

  • Beverly Hills Quadrangle

2. What are the names of the adjacent quadrangles?

  • Canoga Park, Van Nuys, Burbank, Topanga, Hollywood, Venice, Inglewood

3. When was the quadrangle first created?

  • 1995

4. What datum was used to create your map?

  • North American Datum of 1927
  • North American Datum of 1983

5. What is the scale of the map?

  • 1:24,000

6. At the above scale, answer the following:
a) 5 centimeters on the map is equivalent to how many meters on the ground?

  • 1/24000 = 5/x
  • x=120,000 cm - convert to meters
  • 1,200 meters

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

  • 1/24000 = 5/x
  • x=120,000 in. - convert to miles
  • 1.894 miles

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

  • 1/24000 = x/1
  • x=1/24000 miles - convert to miles
  • 2.636 inches

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

  • 1/24000 = x/3
  • x=3/24000 km - convert to centimeters
  • 12.5 centimeters

7. What is the contour interval on your map?

  • 20 feet

8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:
a) the Public Affairs Building;

  • Decimal Degrees: 34.07407N, -118.43927W
  • DMS: 34 degrees, 4', 26.65''; -118 degrees, 26', 21.37''

b) the tip of Santa Monica pier;

  • Decimal Degrees: 34.00752N, -118.49974W

  • DMS: 34 degrees, 0', 27.07''; -118 degrees, 29', 59.06''

c) the Upper Franklin Canyon Reservoir;

  • Decimal Degrees: 34.121N, -118.409W

  • DMS: 34 degrees, 7', 15.6''; -118 degrees, 24', 32.4''

9. What is the approximate elevation in both feet and meters of:
a) Greystone Mansion (in Greystone Park)

  • 560 feet
  • 170.7 meters

b) Woodlawn Cemetery

  • 140 feet
  • 42.7 meters

c) Crestwood Hills Park

  • 700 feet
  • 213.4 meters

10. What is the UTM zone of the map?

  • Zone 11

11. What are the UTM coordinates for the lower left corner of your map?

  • 34 degrees, 00'; 118 degrees, 0'

12. How many square meters are contained within each cell (square) of the UTM gridlines?

  • 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 Insert your elevation profile as a graphic in your blog.




14. What is the magnetic declination of the map?

  • 14 degrees

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

  • South

16. Crop out UCLA from the map and include it as a graphic on your blog:
