USGS quadrants: an adventure in topography

1. What is the name of the quadrangle?

Beverly Hills Quadrangle

2. What are the names of the adjacent quadrangles?

In a clockwise fashion: Canoga Park, Van Nuys, Burbank, Hollywood, Inglewood, Venice, and Topanga Quadrangles

3. When was the quadrangle first created?

Topography compiled in 1966

4. What datum was used to create your map?

North American Datum (1927 and 1983)

National Gedetic Vertical Datum of 1929

5. What is the scale of the map?

1:24,000

6. At the above scale, answer the following:

a) 5 centimeters on the map is equivalent to how many meters on the ground?

5 cm on the map = 1,200 meters on the ground = 1.2 km

b) 5 inches on the map is equivalent to how many miles on the ground?

5 inches = 1.89 miles

c) one mile on the ground is equivalent to how many inches on the map?

1 mile = 2.64 inches

d) three kilometers on the ground is equivalent to how many centimeters on the map?

3 km = 3000 m = 300000cm/24000 = 12.5 cm on the map

7. What is the contour interval on your map?

20 feet

8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:

a) the Public Affairs Building;

34°4’27”, -118°26’21”

b) the tip of Santa Monica pier;

34° 00’ 30”, -118° 30’ 00”

c) the Upper Franklin Canyon Reservoir;

34° 6’ 12”, -118° 24’ 49”

9. What is the approximate elevation in both feet and meters of:

a) Greystone Mansion (in Greystone Park);

560-570 m

b) Woodlawn Cemetery;

140 m

c) Crestwood Hills Park;

630-640 m

10. What is the UTM zone of the map?

Zone 11

11. What are the UTM coordinates for the lower left corner of your map?

Approximately 361472.27, 3763170.11

12. How many square meters are contained within each cell (square) of the UTM gridlines?

1,000,000 sq meters (1000m x 1000m)

13. Obtain elevation measurements, from west to east along the UTM northing 3771000, where the eastings of the UTM grid intersect the northing. Create an elevation profile using these measurements in Excel (hint: create a line chart). Figure out how to label the elevation values to the two measurements on campus. Insert your elevation profile as a graphic in your blog.

14. What is the magnetic declination of the map?

14° east

15. In which direction does water flow in the intermittent stream between the 405 freeway and Stone Canyon Reservoir?

Water is flowing south.

16. Crop out (i.e., cut and paste) UCLA from the map and include it as a graphic on your blog.
