Lab 3: Neogeography

Miles of My Meals

As a college student, grocery shopping plays an integral part in my life. I have noticed that I tend to consistently eat the same thing for lunch. I eat a turkey sandwich with chips and a glass of oj. I realized that the different foods that comprise my invariable lunch meal are distributed from various places. As a result of this realization I've decided to map the distance between the location where I buy my groceries (Ralphs off Le Conte in Westwood) and places where these foods are distributed. The purpose of this map is to remind myself and other fellow consumers of the distances our meals travel before they even reach the grocery store in order to finally end up in our stomachs. It is important to keep in mind that the location from which the food is distributed is not always the place where the food is grown or produced. However, if one highlights over certain points on the map he or she may find a brief overview of the food's original place of production.

One of my critiques on the My Maps application on Google Maps is the fact that for the sake of this particular map idea I feel limited to only plotting distribution locations of the components of my lunch. I wish I could show the various places and distances travelled starting from the production of the food items to processing to packaging and finally to distributing these entities to their final destination--the grocery store. Yet, plotting these points for each food item makes for a very disorganized visual representation and the message I am trying to make becomes lost in scattered dots. Furthermore, My Maps does not provide much freedom in the topographical visualization of the map nor does it give much freedom in the way my points are labeled.

Nonetheless, I believe the My Maps works as a good application for basic geographical presentations and a good starting point for those presentations that are more complex. I enjoyed the fact that I was able to Google Map something and thoughtlessly add the particular landmark to My Maps, thus, making the map constructing process quick and almost painless. I also appreciated the tutorial Youtube video Google provided for My Maps. This tutorial introduces an opportunity to provide any Internet user the potential to create a Google Map. The map’s generation will not only convey a message the creator aimed to make but it will add to the information database of the Google search engine making this message available to otherwise intangible audiences. This potentially generates yet another form of communication between people around the world and, thus, adding more gravity and more realization of topics these generated maps discuss.

When depicting messages and images on a map one is not merely telling the audience something; one is actively showing them. As the famous saying goes, “Tell me and I’ll forget; Show me and I may remember, Involve me and I’ll understand.” Because of my involvement in actively attempting to find out the distribution points and production sites of all the components that make up my daily lunch meal I now realize the power I hold in where I buy my products. Grocery stores that buy their food locally are less harmful to the environment and more often than not possess safer and healthier foods. The fact that it was so difficult to even find out where half of my items were produced brang nausea to my stomach and hopefully this map may bring about the same bizarre realizations and curiosities in consumption that I now possess.

Lab 2: USGS Topographic Maps

Analysis of 7.5 Minute Map of Beverly Hills

1. What is the name of the quadrangle?

a. The name of the quadrangle is “Beverly Hills Quadrangle” which is located in Los Angeles, California.

2. What are the names of the adjacent quadrangles?

a. The names of the adjacent quadrangles are: Canoga Park (1), Van Nuys (2), Burbank (3), Topanga (4), Hollywood (5), Venice (7), Inglewood (8).

3. When was the quadrangle first created?

a. The quadrangle was first created in 1995.

4. What datum was used to create your map?

a. The datum used to create this map was the National Geodetic Vertical Datum of 1927 and the North American Datum of 1983.

5. What is the scale of the map?

a. The scale of the map is 1:24,000

6. At the above scale, answer the following:

a. 5 centimeters on the map is equivalent to how many meters on the ground?

i. RF = map/ground = 0.5 cm X 1/24,000 X 1m/100cm = 1200 meters

b. 5 inches on the map is equivalent to how many miles on the ground?

i. RF= map/ground = 1(5in)/24,000(5in)à 5in:120,000inà120,000in/63,360in = 1.89 miles

c. One mile on the ground is equivalent to how many inches on the map?

i. RF=map/ground = 63,360in/1mile X 1/24,000 = 2.64in

d. Three kilometers on the ground is equivalent to how many centimeters on the map?

i. RF= map/ground = 3km X 100,000cm/1km X 1/24,000= 12.5cm

7. What is the contour interval on your map?

a. The contour interval on my map is 20 feet.

8. What are the approximate geographic coordinates in both degrees/minutes/seconds and decimal degrees of:

a. The Public Affairs Building;

DD: 34.07°N, -118.43°W;

D/M/S: 34°04’12”N, -118°25’48”W

b. The tip of Santa Monica pier;

DD: 34.00°N, -118.50°W;

D/M/S: 34°0’28”N, -118°30’60”

c. The Upper Franklin Canyon Reservoir;

DD: 34.12°N, -118.41°W;

D/M/S: 34°7’12”N, -118°24’36”W

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

a. Greystone Mansion (in Greystone Park);

570 ft; 170.736m

b. Woodlawn Cemetery;

140ft; 42.672m

c. Crestwood Hills Park

660ft; 201.17m

10. What is the UTM zone of the map?

a. The UTM zone of the map is zone 11.

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

a. The UTM coordinates for the lower left corner of my map are 3763000 northing and 362000 easting.

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

a. 1,000,000 square meters are contained within each cell of UTM gridlines.

13. Obtain elevation measurements, from west to east along the UTM northing 3771000, where the easting 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.

a.

Figure 1. Elevation profile from west to east along the UTM northing 377100, where the eating of the UTM grid intersect the northing. The points that have a yellow border are the two measurements that include the UCLA campus.

What is the magnetic declination of the map?

a. The magnetic declination is 14°

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

a. The water in the intermittent stream between 405 freeway and Stone Canyon Reservoir is flowing in the North to South direction.

16. Crop out (ie. Cut and paste) UCLA from the map and include it as a graphic on your blog.
