In the North: Van Nuys Quadrangle
In the Northeast: Burbank Quadrangle
In the West: Topanga Quadrangle
In the East: Hollywood Quadrangle
In the South: Venice Quadrangle
In the Southeast: Inglewood Quadrangle
3. When was the quadrangle first created? – The quadrangle was first created in 1966.
4. What datum was used to create your map? – The following three datum were used to create my map:
The first datum is the North American Datum of 1927 (NAD 27).
The second datum is the North American Datum of 1983 (NAD 83).
The third Datum was the National Geodetic Vertical Datum of 1929.
5. What is the scale of the map? – The scale of the map is 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?
5cm x 24,000 = # of cm on the Earth, or 120,000cm. Then when 120,000 cm is divided by 1000, the resulting answer is 1,200m. So, every 5cm on the map is equivalent to 1,200m.
b. 5 inches on the map is equivalent to how many miles on the ground?
5 in x 24,000 = # of inches on the Earth, or 120,000in. Then when 120,000 is divided by 12 (to convert to feet), the 5 inches represents 10,000 feet. Then, to convert to miles, 10,000ft is divided by 5,280ft (the # of ft per mile), and the answer is 1.894 miles. Therefore, every 5 inches on the map equates to 1.894 miles.
c. One mile on the ground is equivalent to how many inches on the map?
This can be set up as a ratio, since we already know that 1.894 miles = 5 inches. Therefore, 1mile/1.894miles = x/5 inches, or 1.894x=5. Therefore, 5/1.894=x, or 2.64 inches on the map.
d. Three kilometers on the ground is equivalent to how many centimeters on the map?
This can also be set up as a ratio, since we know that 5 cm on the map = 1,200 meters on the ground. Since 1,200/1,000=1.2 km, 5 cm on the map also equals 1.2km. Therefore 1.2km/3km=5cm/xcm, or 3(5)=1.2x, which is 15=1.2x. 15/1.2=12.5. Therefore, every 12.5 cm on the map represents 3 km on the ground.
7. What is the contour interval on your map? – The contour interval on the map is 20 feet. However, it also has a supplementary contour interval of 10 feet.
8. What are the approximate geographic coordinates in both degree/minutes/seconds and decimal degrees of:
a. The Public Affairs Building:
34°4’30”N, 118°26’30”W, or 34.075°N, -118.484°E
b. The tip of the Santa Monica pier:
34°0’30”N, 118°29’30”W, or 34.0083°N, -118.492°E
c. The Upper Franklin Canyon Reservoir
34°7’05”N, 118°24’30”W, or 34.12°N, -118.41°E
9. What is the approximate elevation in both feet and meters of:
a. Greystone Mansion (in Greystone Park)
560ft, or 170.668m
b. Woodlawn Cemetary
140ft, or 42.672m
c. Crestwood Hills Park
690ft, or 210.312m
10. What is the UTM Zone of the map? – The UTM zone of the map is Zone 11.
11. What are the UTM coordinates for the lower left corner of your map? – The UTM coordinates for the lower left corner of my map are 3763000 m North, 362000 m East.
12. How many square meters are contained within each cell (square) of the UTM gridlines? – Since each box is approximately 3 inches, we can multiply 3 x 24,000 to get 72,000 inches per UTM cell (since the scale is 1:24000). Then 72,000/12 results in 6,000 ft along each baseline. Then 6,000ft/5,280ft = 1.136 miles. 1.136 miles x 1.61 (conversion rate from miles to km) = 1.8295km. 1.8295km x 1,000 = 1,829.54 meters per base. Then, (1,829.54)2 = 3,347,236m2, which shows that each cell is approximately 3,347,236m2.
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.
