The pitfalls, potential and consequences of neogeography.
Neogeography applications in todays world are extremely helpful for illustrative and non-formal uses. Anyone with access to a computer and minimal familiarity with google maps, yahoo maps, or a different online map service, can put together a map to illustrate a certain point or to give directions.
The fact that so many tools are now available for non-experts to create a map is terribly exciting for someone like me who has liked and had an interest in geography all his life. These tools not only allow one to explore various regions of the world such as boundaries and topography, but to also make assessments on various geographically related topics regarding any particular area. The danger with Neogeography is the high degree of responsibility, I feel, one must take in creating and presenting a map from a pre-existing toolset. As I've come to learn, all maps may reflect various degrees of distortions depending on their projection method, but also, depending on the point of view being illustrated by the person creating the map, biases must be considered. In topics of controversial relevance, particular importance and analysis of the map's creation method must also be considered in making an objective use of such map. There are many people out there, perhaps even a majority, who may think of maps as absolute points of reference. An awareness of spatial projection on a map, their methods, and the knowledge that not all maps are 100% accurate lead to a reflection on how best to use a pre-existing toolset for map creation, and also, most importantly, for what purpose.
Neogeography has brought a higher awareness of surroundings in people who have now begun to rely on online maps or navigation devices to realize their daily tasks by getting easily to where they need to go. This is a great result of the existence of these maps and navigation devices. People who may not have been aware of the topography or geographical general shape of their surroundings, now can see them projected on a screen. A risky consequence of the availability of pre-existing toolsets like this comes when people may use such pre-existing maps without considering it's source or creation techniques to illustrate points of social, religious or political nature. I believe we may be getting to the point where disclaimers on a map may need to be required as to their creation and source. Especilly when illustrating topics or points of controversial nature.
Lab 2
Lab 2 Answers:
1. What is the name of the quadrangle?
Beverly Hills Quadrangle
2. What are the names of the adjacent quadrangles?
1. Canoga Park
2. Van Nuys
3. Burbank
4. Topanga
5. Hollywood
6.
7. Venice
8. Inglewood
3. When was the quadrangle first created?
1995
4. What datum was used to create your map?
North American Datum of 1927 (NAD 27). Projection and 100 meter grid:
Datum of 1983 (NAD 83) is shown by dash corner ticks.
5. What is the scale of the map?
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?
1 inch on map = 24 000 inches on the ground (or 609.6 mts.)
5cm = 1.96 inches (on the map)
5cm on the map = 1194.8 mts. on the ground
b) 5 inches on the map is equivalent to how many miles on the ground?
1 inch on the map = 0.37 miles on the ground
5 X 0.37 = 1.85 miles on the ground
5 inches on the map = 1.85 miles on the ground
c) one mile on the ground is equivalent to how many inches on the map?
1 mile on the ground = 0.37 in on the map
d) three kilometers on the ground is equivalent to how many centimeters on the map?
If
1194.8 mts. on the ground = 5cm on the map
and
3 km = 3000 mts.
then
.05 mts (5 cm) X 3000 mts = 150 mts / 1194.8 mts = .12 mts.
3 km on the ground = 12 cm on the map.
7. What is the contour interval on your map?
20 feet

Universal Traverse Mercator, zone 11 10 000 foot ticks: California Coordinate System of 1927 (zone 7)
11. What are the UTM coordinates for the lower left corner of your map?
Latitude 34o 00' Longitude 118o 30' ( 30 / 118.5)

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.

14o / 249 mils
15. In which direction does water flow in the intermittent stream between the 405 freeway and Stone Canyon Reservoir?
Towards the South East
16. Crop out (i.e., cut and paste) UCLA from the map and include it as a graphic on your blog.

Geog 7 Lab 1
Map of Vienna in 1827.
Map source: http://www.tonalsoft.com/enc/v/vienna.aspx
From the encyclopedia of microtonal music.
I was shown a similar map of Vienna from this era earlier during my music history class. I found it interesting for several reasons:
1) Because I lived in Vienna for 1 year between 2008 and 2009, and it is interesting to see, both, how the city has changed, and how in some areas it remains the same.
2) It shows how the city was so contained by its walls still at that time.
3) It shows how considerably vast the city was then, and yet, how much smaller it is compared to its size today.
4) From a music history perspective it is also very interesting to see what the city was like during the lifetime of the great composer Beethoven. For me this is of special interest, as I am a music major.
5) It is fun for me to see what the surroundings of the Theaters in Vienna where I have worked were like at the time (Wiener Staatsoper and Theater an der Wien).
2. Map of the region of North Rhein Westphalia in Germany.
source: http://commons.wikimedia.org/wiki/File:North_Rhine-Westphalia_topographic_map_04V.svg
This map shows the area surrounding Osnabrueck which I visit twice per year to visit my daughter.
It is always interesting to me to look at a map of her area so I familiarize myself better each time before I go visit there. We can see that The Netherlands border is quite close to this area. In many visits to Osnabrueck (which is actually not shown in this map because it is technically in the region of Lower Saxony in its southernmost tip) I have not found it to be a region that offers much in terms of touristic activity, and I am always trying to explore its surroundings. I shall become interested in the near future in exploring the cities further to the south such as Cologne and Dusseldorf.
3. Map of the World's resources by country.
source: http://www.mint.com/blog/trends/mint-map-the-worlds-resources-by-country/
This map is interesting to me because it shows Mexico's raking in the worldwide production of silver. The city where I grew up, Guanajuato, Mexico, used to be the number one producer of silver in the world during the times of the Spanish Colony. After years of exploiting Guanajuato's mines we can see that Mexico's silver production has decreased quite a lot. It is also interesting that many of the mines that still produce silver in that area, are actually now owned by foreign companies.
