Lab 2 - USGS Topographic Map of Beverly Hills

1.  The name of the quadrangle is the 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 horizontal datum used to create this map is the North American Datum of 1927 and the North American Datum of 1983. The vertical datum used to create this map is the National Geodetic Vertical Datum of 1929.
5.  The scale of the map is 1:24000.
6.   a) 5 cm x (1 m/ 100 cm) x 24000 = 1200 m
     5 cm on the map is equivalent to 1200 meters on the ground.
b) 5 in. x (1 ft./12 in.) x (1 mile/5280 ft.) x 24000 = 1.894
     5 inches on the map is equivalent to 1.894 miles on the ground.
c) 1 mile x (63360 in./ 1 mile) x (1/24000) = 2.64 inches
     1 mile on the ground is equivalent to 2.64 inches on the map.
d) 3 km x (100000 cm/1 km) x (1/24000) = 12.5 cm
     3 km on the ground is equivalent to 12.5 cm on the map.
7.  The contour interval on the map is 20 feet.         
8.   a) Public Affairs Building:
     34° 04’ 28” N, 118° 26’ 21” W
     34.075, -118.439°                             
b) Tip of Santa Monica Pier:
     34° 00’ 25” N, 118° 29’ 52” W
     34.007, -118.498
c) Upper Franklin Canyon Reservoir:
     34° 07’ 15” N, 118° 24’ 36” W
     34.121, -118.410
9.   a) Greystone Mansion:
     570’
     173.736 m
b) Woodlawn Cemetery:
     140’
      42.672 m
c) Crestwood Hills Park:
     750’
     228.6 m
10. The UTM zone of the map is zone 11.
11. The UTM coordinates for the lower left corner of the map are 361.5 Easting, 3763 Northing.
12.   1,000,000 square meters are contained within each cell of the UTM gridlines.
13.  
14. The magnetic declination is +14°.
15. The water flows south in the intermittent stream between the 405 freeway and Stone Canyon Reservoir because the elevation decreases as you move south along the stream.
