Week 2: USGS Topographic Maps

Lab 2:

1) The quadrangle is called the Beverly Hills Quadrangle (Located in Los Angeles County, CA).

2)

NW: Canoga Park
N: Van Nuys
NE: Burbank
W: Topanga
E: Hollywood
S: VeniceSE: Inglewood

3) 1966
4) North American Datum of 1927 and North American Datum of 1983 were used to create the map.

5) The scale is 1:24,000.

6)

a. [1/24,000] = [5 cm/d) d= 120,000 cm
[120,000 cm] x [1 m/100 cm] = 1,200 m

b. [1/24,000] = [5 in/d]
d= 120,000 in
[120,000 in] x [1 ft/12 in] x [1 mile/5,280 ft] = 1.8939 miles

c. [1/24,000] = [d/1 mile]
[1/24,000] miles x [5280 ft/1 mile] x [12 in/1 ft] = 2.64 in

d. [1/24,000] = [d/3 km]
d= .000125 km
[.000125 km] x [1000 m/1 km] x [100 cm/1 m] = 12.5 cm

7) 20 feet

8)
a. 34*04'26'' N, 118*26'21'' W or 34.074*N, 118.439*W

b. 34*00'27'' N, 118*29'58'' W or 34.008*N, 118.499*W

c. 34*07'13'' N, 118*24'36'' W or 34.120*N, 118.41*W

9)
a. 580 ft or 176.78 m
b. 140 ft or 42.672 m
c. About 650 ft or 198.120 m

10) Zone 11

11) 3,763,000 m N, 361,500 m E

12) 1 square kilometer

13)

14) The magnetic declination is 14 degrees (or 249 Mils) East.

15) The water flows south because the elevation is higher at the most northern part of the map and decreases as the stream goes south.
