1.      What is the name of the quadrangle?

Beverly Hills quadrangle.

2.      What are the names of the adjacent quadrangles?

1. Canoga Park

2. Van Nuys

3. Burbank

4. Topanga

5. Hollywood

7. Venice

8. Inglewood

3.      When was the quadrangle first created?

Year of 1966

4.      What datum was used to create your map?

2 horizontal datum: North American Datum of 1927 and 1983

1 vertical datum: National Geodetic vertical datum of 1929

5. What is the scale of the map?

 R.F. = 1:24000

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 = map/ground

 1/24000 = 5cm/ground

Ground= 5*24000cm

             = 120000cm

             = 1200m  

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

1/24000= 5inches/ ground

Ground = 5*24000 inches

             = 120000inches

             = 1.8939 miles

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

1/24000= map/ 1mile

Map=1/ 24000 miles

       = (63360inches /1mile) * (1mile/ 24000)

       = 63360/ 24000 inches

       = 2.64 inches

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

1/24000= map/ 3km

Map= 3/24000 km

        = (100000cm/1km)*(3km/24000)

        = 12.5 cm

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;

Longitude (P.A.)= 118.30’-x

Distance( left- right)/Distance(left-P.A.)= 7.5’/x = 70cm/33cm

x= 3.54’

118.30’- 3.54’= 118.26.46’  

0.46’=60”*0.46=27.6”

Therefore, the longitude is 118. 26’28”

Decimal degree:

 26minutes*60seconds= 1560 sec

1560 + 28= 1588 sec

1588/3600 sec=.441 degree

Therefore, the longitude is 118.441 degree

Latitude (P.A.)= 34.07’30”-x

Distance( up- down)/Distance( up-P.A.)= 7.5’/x = 28.7cm/ 11.7cm

X= 2.45’

34.07’30”- 2.45’= 34.4.55’30”  

0.55’=60”*0.55=33”

34.04’63”=34.05’03”

Therefore, the latitude is 34.05’03”

Decimal degree:

5 minutes*60seconds= 300 sec

300 + 3= 303 sec

303/3600 sec=.0841 degree

Therefore, the latitude is 34.084 degree

b) the tip of Santa Monica pier;

Longitude= 118.29’52” (118.498 degree)

Latitude= 34.00’31” (34.009 degree)

c) the Upper Franklin Canyon Reservoir;

Longitude= 118.24’39”  (118.411 degree)

Latitude= 34.07’12” (34.12 degree)

9. What is the approximate elevation in both feet and meters of:

a) Greystone Mansion (in Greystone Park);

600feet- 20feet = 580 feet

580 feet = 176. 784 meters

b) Woodlawn Cemetery;

140 feet

42.672 meters

c) Crestwood Hills Park;

Around 630 feet

192.024 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?

361.5 Easting and 3763 Northing

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

1000*1000m= 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 degree

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

Water flows from north to south.

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