Lab 2: USGS Topographic Maps

1.) Beverly Hills Quadrangle, California-Los Angeles Co.
2.) Beverly Hills Ca.
3.) The quadrangle was first creted in 1995.
4.) North American Datum of 1927 (NAD 27) and North American Datum of 1983 (NAD 83).
5.) The scale of the map is 1:24,000.
6.  a.) 5 centimeters on the map is equivalent to 120 meters on the ground.
     b.) 5 inches on the map is equivalent to 1.893 miles on the ground.
     c.) 1 mile on the ground is equivalent to 2.64 inches on the map.
     d.) 3 kilometers on the ground is equivalent to 12.498 centimeters on the map.
7.) The contour interval on the map is 20 feet.

9. a.) Elevation: Greystone Mansion (in Greystone Park) = ranges from approx. 580 to 540 feet/176.784 to 164.592 meters.
    b.) Elevation: Woodland Cemetery = approx. 140 feet/42.672 meters.
    c.) Elevation: Crestwood Hills Park = ranges from approx. 600 to 880  feet/182.88 to 268.224 meters.
10.) Universal Transverse Mercator, zone 11.
11.) the UTM coordinates for the lower left corner of the map are ³7 63, ³62.
12.) 1,000 meter increments between UTM lines translates into 1,000,000 square meters.
13.) This is a rough estimation for the elevation levels among the UTM grid lines.

14.) The magnetic declination of the map is 14 degrees E.
15.) Water in the intermitten stream between the 405 freeway and the Stone Canyon Reservoir flows south.
