Final Lab: Station Fire 2009

In August and September of 2009 the largest fire in L.A. County history occurred, the Station Fire. As usual, firefighters did their best to put out the fire, and in the process, two firefighters were killed. (Incident Information System). Furthermore, not only were two brave men killed, but there was a possibility that nearby residents suffered health effects due to smoke produced by such a large fire. In the following report, I attempt to show that although the perimeter of the fire did not reach populated areas of Los Angeles County, the smoke and residue from the Station Fire were close enough to populated areas to cause health complications.

In Figure 1, the map shows the perimeter of the Fire station in relation to topography of Los Angeles County. However, further mapping was required in order to see which, or if, populated areas of L.A. County were within that perimeter. As Figure 1.2 shows, there were no populated areas that were directly affected by the fire. But it is clear that there are a couple of populated areas south of the fires that were in danger of the fire. Even though this map shows that the fire did not reach populated areas, reports do show that homes were destroyed. In fact, 21 homes were destroyed and 1,200 were at risk (NASA).

Figure 2 was published by the National Oceanic and Atmospheric Administration (NOAA), and from it one can see were Los Angeles is located in relation to the smoke produced by the Station fire (2009). This is an important satellite image to look at because it gives us an idea of the general pattern that the smoke traveled.

According to a report from the Division of Environmental Health in Washington, smoke from fires is toxic to the lungs because it is made up of toxic gases, and can cause breathing problems (Washington State). This is especially dangerous to those who already have breathing problems such as asthma. Moreover, this is significant because 20% of people who don’t even know that they have respiratory problems have “hyper-reactive airways.” This means that they are more likely to have complications because of the bad air quality produces by the smoke from the fire (Global Times).

In conclusion, it is clear that the Station Fire was dangerous not only because it was large and spread over a vast part of Southern California, but because it had adverse side effects as well. The health of people in the nearby populated areas was undoubtedly affected.

Lab #5: Map Projections

This exercise was somewhat difficult at first. Although I read through the Wikipedia page about map projections, it was hard to figure out which options to choose in the ArcMap to make a map that represented the various map projections. Therefore, it took a little more research in order to figure it all out. However, overall, this exercise was fun, because it was interesting to see how one can manipulate a single map into various shapes that would preserve different aspects of it.

Significance: It is important to know the different types of map projections, because each changes the map so that different elements are changed or stay the same. For example, equidistant map projections, like the Equidistant Conic World Map that I created, distance was preserved from some standard point or line. This is different from an equal-area map projection, like the Sinusoidal World Map that I created, because equal-area projections preserve area. Furthermore, the maps are significant because it is important to know why one type would be used over another. While researching map projections, I found out that Mercator projections are most popular because it preserves angles and because of it is a rectangular map.

Perils: Obviously one of the biggest perils of map projections is the fact that each type preserves certain elements while distorting others. For example, the Stereographic World Map that I created preserves angels but does not preserve distance or the area of figures. Sometimes these kinds of distortions are acceptable, but other times they are not. Therefore, because there are various map projection types, one must be careful as to which one they choose.

Potential: Working with map projections was somewhat fun. As mentioned, it was interesting to see how a single map can be manipulated to represent the same thing (in this case, the world) in several different ways. Therefore, one of the major potentials of map projections is that they allow us to represent the Earth or parts of its surface in a wide variety of scales.

Lab #7: A look at the U.S. population by Race

In this map, it shows the Asian population across the US ranked by percentage. From the legend, you can see where there are higher concentrations of Asian populations. The map is not as clear as I wanted it to be, because I forgot to change one of the headings, so it is not very clear that the legend is referring to the Asian population only. If I had more time, I would have gone back to fix this minor yet significant problem.

Lab #4: Proposed Airport Expansion

Write a four paragraph review of your ArcMap experience that discusses the potential and pitfalls of GIS.

Working through the ArcMap tutorial was quite an experience. It was very time consuming and meticulous work; however, I do feel as though it was helpful and somewhat fun.

At first, working with ArcMap was very frustrating. There were so many small steps to work through. It seemed almost pointless. However, as I continued to work through the tutorial, it was obvious to see that in order to create more advanced maps or scales I had to know how navigate my way through the simple toolbars. I knew that no matter what I was being asked to do, I could figure out how to do it especially as I continued through the tutorial.

I know that we were asked to go through the tutorial at least three times, but I felt as though I went through it many more times! This was one of the pitfalls, because after I had been working on one of the maps for a while, I would make one simple mistake such as clicking the wrong icon on the toolbar and I couldn't undo my mistake. This was frustrating. After a few trial and errors I realized how to undo my mistakes or how to go back and fix them. So this is definitely a program that requires a lot of practice.

I think that one of the good things about GIS is that it really allows you to do a lot in terms of creating maps, legends, and so forth. It goes beyond a simple map creation and allows you to really create something that focuses on what you're interested in. For example, in this tutorial we were looking at the noise affecting schools and houses near the airport and increased traffic along major roads. By looking at this data and analyzing it using ArcMap, we were able to create land use maps and create a poster that illustrates proposed airport expansion.

Working through this tutorial and creating the poster also helped me to appreciate other ArcMap creations that I have seen. I would have never known how much work goes into creating such a simple looking illustration!

Lab #3: My Google Map "Tour of Athens, Greece"

View Tour of Athens, Greece in a larger map





This summer, I traveled to Greece. Our first stop was Athens. I was initially very excited about going to Athens, because I knew a little about the history so it seemed as though it would be quite a site. However, when I arrived at the hotel, I was a little disappointed; it wasn't as fascinating as I had thought. But once I began to explore the area and after making my way to the more touristy parts of the city, I realized that it really was an amazing city. There is a lot of walking in Greece, so using Google Maps I created a map that includes several "hot spots" in Athens.

Initially, it was difficult to map my route. I wanted to share the nice shops and amazing restaurants in Athens. The main issue I had while creating the map was that it was all in Greek! Of course, I remember the names of a lot of the places where I went, but it was hard to locate them amidst the many other locations that the map shows, so this was definitely one of the pitfalls. What was even more difficult was trying to pinpoint the location of places in areas where they didn't necessarily have a building. For example, on my map I marked a gyro shop. This was difficult to pinpoint because it is located in a shopping district. So it helped to know the overall location of the shopping district, but it was difficult to mark the exact location of the gyro shop. However, there was a plus side to using neogeography and that was that I was able to include a picture along with my marker. I'm sure not everyone knows what a gyro is (Greek "taco"), so it was helpful to be able to include a picture. Therefore, neogeography has much potential, because through the media attachments it helps to make sense of these places and the things you can find within them.

Lastly, I realized that one of the major consequences of neogeography is its power to not only locate places but the power of making sense of these places for others as well. I don't think I could have better explained to someone how to get from their hotel to the Parthenon. More importantly, I wouldn't have been able to direct them in a way so that they, too, could have the same walking tour experience that I had.

Lab #1

Map #1 : 

I found this map on the website: http://www.worldtimeexplorer.com/ which is a website that shows the local time of any location on earth. At first, what caught my eye about this map is that it is very colorful. From experience with maps, I knew that the colors probably corresponded to something; however, I thought that the different colors related to different temperatures. The color key at the bottom is also interesting, because although it seems as though it is a key, it does not have any words to explain what it means. Therefore, another reason why I found this map interesting was because it seems to have a lot going on, but if I had hadn't known what website it came from then I probably would have no idea what it was trying to portray. 

Map #2: 

While looking for maps, I wanted to find one of Greece. I found this map on the website http://www.greece-map.net/mainland-greece.htm. It basically just serves as a resource for maps of Greece. This map is very simple and straightforward. It is colorful but only colorful enough so that countries are distinguished from one another. I liked this one, because a lot of the times maps are confusing and too detailed. The thing that I found most interesting about this map is that the major cities within Greece are titled differently than one would expect. For example, many might not know that "Attica" is Athens. 

Map #3:

I found this map on the website  http://gpsinformation.info/penrod/62S/62-78.html. Therefore, what I found interesting about this map is that it was displayed on a website that promotes GPS devices. It is very detailed as you can tell from the many lines and dots. It is somewhat 3-D with the raised hills and the different contour lines. I also thought the contour lines were interesting, especially because it is something that we recently learned about in class, and I did not know that that's what they are called. Also, it's interesting how vague this map is because it has no labels, compass, or any other point of reference in order to know where this location is.
