1     1. What is the name of the quadrangle?
Beverly Hills, CA
       2. What are the names of the adjacent quadrangles?
Canoga Park , Van Nuys, Burbank, Topanga, Hollywood, Venice, and Inglewood

3. When was the quadrangle first created?
It was created in 1966.
      4. What datum was used to create your map?
National American Datum of 1929, North American Datum of 1927(NAD 27), North American Datum of 1983(NAD 83).
5. What is the scale of the map?
The scale is 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?
The meters on the ground= 5 x 24,000 = 120,000 cm= 1200 m (1m =100cm)
b) 5 inches on the map is equivalent to how many miles on the ground?
The inches on the ground= 5 x 24,000 = 120,000 inches= 1.8939miles
c) one mile on the ground is equivalent to how many inches on the map?
1 mile =63360 inches
63360/24000=2.64 inches on the map
1 mile on the ground is equal to 2.64 inches on the map.
d) three kilometers on the ground is equivalent to how many centimeters on the map?
3 km= 3000 m = 300,000 cm
300,000/24,000 =12.5 cm on the map
Three kilometers on the ground is equal to 12.5cm on the map.
7. What is the contour interval on your map?
It is 20 feet.
8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:
a) the Public Affairs Building;
N 34°4'40", W 118 °26'15"
N34.0778 , W 118.4375°
b) the tip of Santa Monica pier;
N 34 °0'40", W 118°30'0"
N34.0111°, W118.5°
c) the Upper Franklin Canyon Reservoir;
N 34°6'15", W 118°24'40"
N34.1042°, W118.4111°
9. What is the approximate elevation in both feet and meters of:
a) Greystone Mansion
560 feet =170.688m
b) Woodlawn Cemetery
140 feet =42.672m                      
c) Crestwood Hills Park
600~650 feet = 182.88~198.12m
10. What is the UTM zone of the map?
UTM zone 11.
11. What are the UTM coordinates for the lower left corner of your map?
3763000m N and 361500m E
12. How many square meters are contained within each cell (square) of the UTM gridlines?
1000 x 1000 =1000000 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.




14. What is the magnetic declination of the map?

14˚ E

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

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