Lab 3: Neogeography

The following is a map of all of the places I want to go in the world because of their natural (and in some cases man-made) beauty.

 Neogeography, or user-generated mapping, has huge potential because it allows any user to input his or her geographic knowledge, and make it interactive and accessible to anyone who has internet access.  Because it is user-oriented, neogeography lends itself to infinite purposes involving displaying and using spatial and location-based data.  

Though it can be an amazing tool, neogeography has its downsides.  For one, because the data is user-generated and for the most part goes unregulated by an authority, the information can be unreliable or deceptive.  Furthermore, there are concerns about terrorist use of satellite imagery to plan attacks.  However, because Google Maps and Earth images are usually a few months to years old, the information is not necessarily as useful as a potential terrorist would hope.  Another concern is personal privacy, as citizens are caught on Google Maps' Street View without even knowing it.  

As it grows in popularity, Nneogeography is creating a whole new way of using and interacting with maps and spatial data.

Lab 2: USGS Topographic Maps

1. The name of the quadrangle is Beverly Hills.
2. The adjacent quadrangles are Canoga Park (NW), Van Nuys (N), Burbank (NE), Topanga (W), Hollywood (E), Venice (S), and Inglewood (SE). 
3. The quadrangle was first created in 1966.
4. To create the map, North American Datum of 1927 (NAD 27) and North American Datum of 1983 (NAD 83) were used.
5. The scale of the map is 1:24,000.
6. a) 5 cm on the map = 1200 m on the ground
    b) 5 in. on the map = 0.189 mi. on the ground
    c) 1 mi. on the ground = 2.64 in. on the map
    d) 3 km on the ground = 12.5 cm on the map
7. The contour interval on the map is 20 ft.
8. a) Public Affairs Building: (34°N 4' 28" and 118°W 26' 21") or (34.074539, -118.439124)
    b) Tip of Santa Monica Pier: (34°N 0' 27" and 118°W 30') or (34.007580, -118.499925)
    c) Upper Franklin Canyon Reservoir: (34°N 7' 12.5" and 118°W 12' 37") or (34.120152, -118.410286)
9. a) Greystone Mansion: ~600 ft.
    b) Woodlawn Cemetery: 147 ft.
    c) Crestwood Hills Park: 747 ft.
10. UTM zone 11
11. UTM coordinates of bottom left of map: 362E and 3763N
12. 1,000,000 square meters are within each UTM cell
13.


14. The magnetic declination of the map is 14°.
15. The water in the stream between the 405 and Stone Canyon Reservoir flows from North to South.

Lab 1: Interesting Maps

This map shows the distribution of world hunger by showing the percentage of undernourished people in each country of the world. I find this map interesting because I find it interesting to see in which areas of the world hunger is most prevalent.  Also, it is amazing that in a number of African countries, over 35% of the population is undernourished.  It is also surprising to me to see how many countries' populations have a rate of undernourishment of over 18%.  This map was created by the World Food Programme, and is available at http://www.wfp.org/hunger/map.  





This map describes the percentage of energy that each country imports of its total energy use. I find it interesting because it demonstrates how interconnected our world is because so many countries rely on others for a significant amount of their energy. I also find it interesting that according to the map, the U.S. imports about 68% of its energy.  Energy is essential to our society, and it is interesting that other countries have the ability to severely cripple us by failing to provide us with fuel.  This map was created by the World Bank and can be found at http://data.worldbank.org/indicator/EG.USE.COMM.FO.ZS?display=map.  





This map shows the percentage of the population in each country of the world that has access to safe drinking water.  I find this interesting because it is amazing that in a number of countries, despite the level of technology in our world, fewer than 40% of people have access to something as basic as drinkable water.  The map was created by the United Nations Environment Programme and can be accessed at http://www.grida.no/graphicslib/detail/access-to-safe-drinking-water_de64#.
