Lab 2 - Beverly Hills Topographic Map

  1. The name of the quadrangle in the California Los Angeles County Sector is “Beverly Hills Quadrangle.”


2. The adjacent angles are Burbnk, Canoga Park, Hollywood, Inglewood, Topanga, Van Nuys, and Venice.


3. The Quadrangle was first created in 1995.


4. The datum used to create is the NGV Datum 1929 (National Geodetic Vertical Datum 1929).


5. The scale used for the map is the Large Scale for Topographic Maps: 1:24,000.

6. 
A) At the Above Scale, 5 meters are equal to 1,200 meters on the ground world.
B) 5 inches on the map is equivalent to 1.893342 Miles (5*24,000/63360).
C) 1 mile on the ground is equal to 2.64 inches on a map.
D) 3 kilometers on the ground is equivalent to 12.5 centimeters on the USGS map.

7. The contour interval/line is 20 feet on this map.

8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees:
A) The Public Affairs Building Location: 34 04'28"N, 118 26'20"W under degree/minutes/seconds system and 34.0713 N, 118.4366 under decimal degrees system.
B) The Santa Monica Pier Tip Location: 34 00'27"N, 118 30'00"W under degree/minutes/seconds system and 34.0045N 118.5W under decimal degrees system.
C) The Upper Franklin Canyon Reservoir Location: 34 37'12"N, 118 24'36"W under degree/minutes/seconds system and 34.6187N, 118.406W under decimal degrees system.

9. What is the approximate elevation in both feet and meters:
A) Greystone Mansion [Located in Greystone Park]: approximately 600 feet (183 meters)
B) Woodlawn Cemetery: approximately 120 feet (36.6 meters).
C) Crestwood Hills Park: approximately 800 feet (244 meters). The topography of the Crestwood Hills Park region creates contour lines with very little space between each line. Therefore, it is difficult to estimate a precise line in the region.

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

11. 3763000 North (from Equator) 361000 East (from Westernmost point in the Quadrant) are the UTM coordinates for the lower left corner of the map.

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

13.






14. 14 degrees East is the magnetic declination of the map.

15. From North to South is the direction water flows in the intermittent stream between the 405 freeway and the Stone Canyon Reservoir.
