USGS Topographic maps: Beverly Hills

1. What is the name of the quadrangle?
BEVERLY HILLS QUADRANGLE
CALIFORNIA
7.5-MINUTE SERIES

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

3. When was the quadrangle first created?
In 1995

4. What datum was used to create your map?
North American Datum of 1983 (NAD83)

5. What is the scale of the map?

SCALE 1:24 000 or 2000 ft from ground

6. At the above scale, answer the following:

a) 5 centimeters on the map is equivalent to how many meters on the ground?
1cm=240m on the ground on a 7.5 map so 5cm is equivalent to 5cm*240m or 1200m on the ground

b) 5 inches on the map is equivalent to how many miles on the ground?
1 inch in a 1:24000 map is 2000ft so 5 inches is equivalent to 10,000 ft on the ground or 1.893 miles
1ft=.000183 miles

c) one mile on the ground is equivalent to how many inches on the map?
If 2000ft= 1 inch on the map then there is 63360 inches in one mile
so 1 mile is equivalnet to 63360 inches/24000 by dividing the inches in one mile by the the scale of the map one can find the inches equivalent to one mile which = 2.64 inches

d) three kilometers on the ground is equivalent to how many centimeters on the map?
1cm=240m on the ground

1 km= 39 370 inches
3km= 118110 inches
1 inch= 2.54 cm
so 118110 inches divided by the scale can give us the equivalnce of 3km on the map which is 4.92 inches or 12.5 cm on the map.

7. What is the contour interval on your map?

Contour interval is 20ft.

8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:
a) the Public Affairs Building;
(34° 4' 22") and 34.073°
b) the tip of Santa Monica pier;
(34° 0' 25") and 34.007°
c) the Upper Franklin Canyon Reservoir;
(34° 7' 10")) and 34.119°

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

a) The elevation of Greystone Mansion is approximately 550 Feet or 167.68 meters.
b) The elevation of Woodlawn Cemetery is 140 Feet or 42.6 meters.
c) The elevation of Crestwood Hills Park is 800 Feet or 243.90 meters.

10. What is the UTM zone of the map?

The UTM zone of the map is zone 15S

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

The UTM coordinates for the lower left corner of the map is 3630000mE. and 3660000 mN.

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

Each cell (square) of the UTM gridlines contain 100,000 square meters.

13.

14. what is the magnetic declination of the map?

The magnetic declination of the map is 1 (1/2)°.

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

The direction of the water flow is North to South.

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

  1. grade 6/10

    3. FIRST compiled in 1966.

    4. NAD of 1983 AND of 1927

    8. lat/long needs both coordinates for each point. that means a N and a W position for each the degree/min/sec and decimal degrees.

    10. UTM Zone 11.

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

    12. 1,000,000m²
    13. no graph
    14. 14°
    16. needs to be from the USGS topo map.
