Patrick Chew - Lab 2

Week 2 Lab

1. The Quadrangle featured in the map is the Beverly Hills Quadrangle.

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

3. The quadrangle was first created in 1966.

4. The datum is from the North American Datum of 1927 (NAD 27). The North American Datum of 1983 (NAD 83) is also depicted by dashed corner ticks.

5. The scale of the map is 1:24,000 (1 inch on the map is equivalent to 24,000 inches on the ground.

6.

a.     5 centimeters on the map is equivalent to: 1200.9 meters.

                                               i.     5 cm = 1.97 in inches on the map = 47280 inches on the ground = 4,000 ft.

                                              ii.     3940 ft x 0.3048 = 1200.9 meters

b.     5 inches on the map is equivalent to: 1.894 miles.

                                               i.     1 mile = 5280 ft = 63,360 in on the ground

                                              ii.     5 in = 120,000 inches on the ground/63,360 = 1.894 miles

c.      1 mile on the ground is equivalent to: 2.64 inches on the map.

                                               i.     1 mile = 5280 ft = 63,360 in on the ground

                                              ii.     63,360 in/24,000 in = 2.64 inches

d.     3 km on the ground is equivalent to: 12.49 cm.

                                               i.     3 km = 3000 m = 300,000 cm.

                                              ii.     5 cm on map = 1200.9 = 120,090cm/5 =24,018, so 1 cm on map = 24,018 cm on ground.

                                            iii.     300,000 cm/24,018 cm = 12.49 cm on map

7. The contour interval on the map is 20 feet. Supplementary contour interval is 10 feet.

8. The approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of the

e.     Public Affairs Buildling:

                                               i.     DMS: 34°04'26" N and 118°26'21" W

                                              ii.     DD: 34.07398° N and 118.43923° W

f.      The tip of the Santa Monica Pier:

                                               i.     DMS: 34°0’26” N and 118°30’3” W

                                              ii.     DD: 35.00732° N and 118.50073° W

g.     The Upper Franklin Canyon Reservoir:

                                               i.     DMS: 34°7’18” N and 118°25’33” W

                                              ii.     34.12175° N and 118.40907° W

9. The approximate elevation in both feet and meters of:

h.     Greystone Mansion (in Greystone Park): 560 feet = 170.688 meters

i.       Woodlawn Cemetery: 140 feet = 42.67 meters

j.       Crestwood Hills Park: 630 feet = 192.02 meters

10. The UTM zone of the map is UTM Zone 11S

11. The UTM coordinates for the lower left corner of the map are 3763000 and 362000.

12. There are 1,000,000 square meters contained within each cell (square) of the UTM gridlines.

13. See Image Below:

14. The magnetic declination of the map is 14 degrees east of north.

15. The water in the intermittent stream between the 405 freeway and stone Canyon reservoir flows from North to South.
