1. Beverly Hills
2. Canoga Park; Van Nuys; Burbank; Topanga; Hollywood; Venice; Inglewood
3. 1995
4. NAD 27 and the more updated, NAD 83, are the horizontal datum used to create this map. The national geodetic vertical datum of 1929 is the vertical datum used to create this map.
5. The scale of the map is 1:24,000
6. a. (5cm)(24,000)(1m/100cm) = 1,200 meters
b. (5in)(24,000)(1mile/63360in) = 1.89 miles
c. (1mile/24,000)(63360in/1mile) = 2.64 inches
d. (3km/24,000)(1000m/1km)(100cm/1m) = 12.5 centimeters
7. The contour interval is 20 feet.
8. a. (x/7.5 minutes) = (8.65cm/17.5cm)
x = 3.71 minutes
longitude = 118 degrees 30 minutes - 3.71 minutes = 118 degrees 26' 43''
(26/60)+(43/3600) + 118 = 118.45 decimal degrees
(x/7.5 minutes) = (8.4cm/13.9cm)
x = 4.53 minutes
latitude = 34 degrees + 4.53 minutes = 34 degrees 4' 32''
34+(4/60)+(32/3600) = 34.08 decimal degrees
34 deg 4' 32'' N, 118 deg 26' 43'' W
34.08 degrees N, 118.45 degrees W
b. (x/7.5 minutes) = (1.5cm/17cm)
x = 0.662 minutes
longitude = 118 degrees 30 minutes - 0.662 minutes = 118 degrees 29' 20''
(29/60)+(20/3600)+118 = 118.49 decimal degrees
(x/7.5 minutes) = (0.8cm/13.9cm)
x = 0.432
latitude = 34 degrees + 0.432 minutes = 34 degrees 0' 26''
34 + 0 + (26/3600) = 34.007 decimal degrees
34 deg 0' 26'' N, 118 deg 29' 20'' W
34.007 degrees N, 118.49 degrees W
c. (x/7.5 minutes) = (8.4cm/11.6cm)
x = 5.43 minutes
longitude = 118 degrees 30 minutes - 5.43 minutes = 118 degrees 24' 34''
(24/60)+(34/3600)+118 = 118.41 decimal degrees
(x/7.5 minutes) = (13.5/13.9cm)
x = 7.28 minutes
latitude = 34 + 7.28 minutes = 34 degrees 7' 17''
34 + (7/60) + (17/3600) = 34.12 decimal degrees
34 deg 7' 17'' N, 118 deg 24' 34'' W
34.12 degrees N, 118.41 degrees W
9. a. 580 feet
580 feet x 0.3048 meters/feet = 176.78 meters
b. 140 feet
140 feet x 0.3048 meters/feet = 42.67 meters
c. 700 feet
700 feet x 0.3048 meters/feet = 213.36 meters
10. This map is located in UTM zone 11.
11. 361500 meters (easting), 3763000 meters (northing)
12. (1000m)(1000m) = 1,000,000 meters squared, or 1 kilometer squared
13.

14. 14 degrees

15. The water flows south.
