Topographic Maps

1. The name of the quadrangle is Beverly Hills located in Los Angeles County, California.
2. The adjacent quadrangles of Beverly Hills are: Canoga Park, Van Nuys, Burbank, Topanga, Hollywood, Venice, and Inglewood.
3. The quadrangle was first created in 1995.
4. The North American Datum of 1927 and 1983 were used to create this map.
5. The scale of the map is 1:24000 which means one inch is equivalent to 24000 inches.
6. a) Using the conversion of 1cm = 0.3937in, 5cm on the map is equivalent to 1.9inches. 1.9 inches on the map is 47,244 inches on the ground which is also 3,937 feet. Multiplying the measurement in feet by 0.3048 as indicated on the map to find meters, 5cm on the map is equivalent to 1,200 meters.
    b) Five inches on the map is equivalent to 120,000 inches, or 10,000 feet. Since 1 mile is 5,280 feet, 5 inches on the map is equivalent to 1.894 miles.
    c) One mile on the ground is equivalent to 63,360 inches. On the map, 1 mile is 2.64 inches, or 6.70 centimeters.
7. The contour interval on the map is 20 feet.
8. What are the approx. grographic coordinates in both degrees/min/sec and decimal degrees of:
    a) PubAff building: Longitude: 34 degrees 5 minutes 5 seconds, Latitude: 118 degrees 26 minutes 15 seconds;
    b) Tip of SM Pier: Longitude: 34 degrees 15 seconds, Latitude: 118 degrees 30 minutes
    c) Uppter Franklin Canyon Reservoir: Longitude: 34 degrees 6 minutes, Latitude: 118 degrees 24 minutes  50 seconds
9. Approx. elevation in both ft and m of:
    a) Greystone Mansion (in Greystone Park)? 560 ft, or 170.7 meters
    b) Woodlawn Cemetery? 140 ft, or 42.7 meters
    c) Crestwood Hills Park? 760 ft, or 231.5 meters
10. UTM zone of map? UTM zone 11
11 UTM Coords for lower left corner of map?
12. How many sq. m are contained w/in each cell of UTM gridlines? 1,000,000 sq. meters
13.

14. Magnetic declintion of map? 14 degrees
15. In which direction does water flow in the intermittent stream between 405 and Stone Canyon Reservoir? South

16.

This map is from the Philippine's Bureau of Soils and Water Management. This map lays out the areas that have communal irrigation systems (CIS) or national irrigation systems (NIS). I find this map interesting because it shows the lack of irrigation throughout the island. Many different areas of the Philippines are not very urbanized or modern. Most of the people still live in villages and provinces. For myself, being a of Pilipino descent, it helps remind me of the day-to-day struggle that the people have to endure in order to gain access to clean water. Family members travel many miles, as scaled on the map, to get water.

 This map is made from data collected by the United States Geological Survey (USGS). This map shows the seismic activity within the Philippines. I think this map is interesting because it displays where in the Philippines that natural hazards (ex. earthquakes, volcano eruptions, etc.) can affect the islands. This information is very valuable because it allows for us to analyze the risks and effects these environmental risks pose. It also relates to the type of maps we will be making/analyzing throughout the course, or even throughout my courses as an environmental science major. Maps like this also allow me to connect issues that affect areas I take personal interest in, which in this case is the country in which I gain much of my cultural influence from.

This map is from the Commission on Higher Education in the Philippines. It shows the distance of state colleges in the Philippines. The circles give a 50 mile radius reference. I think this map is interesting because it shows the few number of state colleges within this region of the Philippines. We could use these locations and compare them with geographical data such as topography, or data on access to transportation to analyze the ease of access to these institutions.
