1. What is the name of the quadrangle?
Beverly Hills

2. What are the names of the adjacent quadrangles?
Canoga Park, Van Nuys, Burbank, Topanga, Hollywood, Venice, and Inglewood

3. When was the quadrangle first created?
1966

4. What datum was used to create your map?
North American Datum of 1927 (original), North American Datum of 1983 (update)

5. What is the scale of the map?
1:24000

6. At the above scale, answer the following:
a) 5 centimeters on the map is equivalent to how many meters on the ground?
1,200 meters
b) 5 inches on the map is equivalent to how many miles on the ground?
1.89 miles
c) 1 mile on the ground is equivalent to how many inches on the map?
2.65 (or 3) inches
d) 3 kilometers on the ground is equivalent to how many centimeters on the map?
12.5 cm

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° 04' 25" N or 34.0736° N
118° 26' 20" W or 118.4338° W
b) the tip of Santa Monica pier;
34° 0'30" N or 34.0083°
118°29'55" W or 118.4986°W
c) the Upper Franklin Canyon Reservoir;

b) Woodlawn Cemetery;
141 feet or 43 meters
c) Crestwood Hills Park;
636 feet or 194 meters

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?
3,733,000 Easting
362,000 Northing

12. How many square meters are contained within each cell (square) of the UTM gridlines?
1,000,000 sq. meters

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°

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

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