Lab 2

1. What is the name of the quadrangle?
The map is called “Beverly Hills Quadrangle California – Los Angeles Co.”

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

3. When was the quadrangle first created?
The quadrangle was first compiled in 1966.

4. What datum was used to create your map?
The North American Datum of 1927 and the North American Datum of 1983 were used.

5. What is the scale of the map?
The scale is 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 / 100 = .05 m
.05 m x 24,000 = 1200 m

b) 5 inches on the map is equivalent to how many miles on the ground?
5 in x 24,000 = 120,000 in
120,000 in / 63,360 in/mi = 1.8939 miles

c) one mile on the ground is equivalent to how many inches on the map?
1 mile / 24,000 = 1/24,000 mi
1/24,000 x 63,360 in/mi = 2.64 inches

d) three kilometers on the ground is equivalent to how many centimeters on the map?
3 km / 24,000 = .000125 km
.000125 km x 100,000 cm/km = 12.5 cm

6. What is the contour interval on your map?
The contour interval is 20 feet.

8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:
a) The Public Affairs Building is at about 37°04'26"N, 118°26'20"W, or 37.074°N, 118.336°W.

b) The tip of Santa Monica pier is at about 34°00'28"N, 118°29'58"W, or 34.008°N, 118.499°W.

c) The Upper Franklin Canyon Reservoir is at about 34°07'10"N, 118°24'37"W, or 34.1195°N, 118.410°W.

9. What is the approximate elevation in both feet and meters of:
a) Greystone Mansion (in Greystone Park) is at about 600 feet, or 182.88 meters.

b) Woodlawn Cemetery is at about 140 feet, or 42.672 meters.

c) Crestwood Hills Park is at about 600 feet, or 182.88 meters.

10. What is the UTM zone of the map?
The UTM zone is 11.

11. What are the UTM coordinates for the lower left corner of your map?
The UTM coordinates are 3,763,000mN and 361,500mE.

12. How many square meters are contained within each cell (square) of the UTM gridlines?
Each grid cell contains 1,000 x 1,000 = 1,000,000 square 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?
The map is declined 14 degrees per 249 miles from MN.

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

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

    8. you mixed up your lat/long and UTM coordinates
    a) Public Affairs Building - 37°04'26"N, 118°26'20"W; 37.074°N, 118.336°W
    b) tip of Santa Monica Pier - 34°00'28"N, 118°29'58"W; 34.008°N, 118.499°W
    c) Upper Franklin Canyon Reservoir - 34°07'10"N, 118°24'37"W; 34.1195°N, 118.410°W

    11. 3,763,000mN and 361,500mE.
