Lab 2: USGS Topographic Maps

1. Beverly Hills Quadrangle.

2. The names of the adjacent quadrangles are: Canoga Park, Van Nuys, Burbank, Topanga, Hollywood, Venice, and Inglewood.

3. The quadrangle was first created in 1966.

4. The map is produced by the horizontal datums of The North American Datum of 1927 and North American datum of 1983 and the vertical datum of National Geodetic Vertical Datum of 1929.

5. 1 : 24,000

6.

a) 5 cm / x = 1 / 24,000

x = 5 cm(24,000)

x = 120,000 cm

120,000 cm (1 m /100 cm)

= 1,200 meters

b) 5 in/x = 1/24,000

x = 5 in(24,000)

x = 120,000 in

120,000 in(1 ft/12 in)(1 mile/5,280 ft)

= 1.89 miles

c) x/ 1 mile = 1/24,000
24,000 x = 1 mile
x = 1 mile  /24,000
1 mile / 24,000 *(63,360 inches/1 mile)
= 2.64 inches

d) x/3 km = 1/24,000

x = 3 km/ 24,000

x = 0.000125 km

0,000125 km(100,000 cm / 1 km)

= 12.5 cm

7. The contour interval is 20 feet.
