The map I made is a map of the my favorite places. I love the places. Also, I go to the places when I need some foods or take the classes for my studying. My school has amazing architectures and beautiful trees. Also, my apartment is a very nice place for me because it's my home!!

Neogeography is a new movement that combines maps and technology.

From Neogeography people can create their own maps. It is greatly beneficial as it allows everyone to share information with people. Also, Neogeography can help to increase geographical awareness, and make maps more readily accessible. Furthermore, Neogeography is a very interactive tool, allowing the general public to become more involved and interested in geography. While Neogeography is allowing everyone to be a geographer, there are consequences and pitfalls to this "new geography". Since the information in Neogeography is all voluntary, the people uploading the information have no reason to present unbiased, accurate data. This can result in misleading and unreliable information that can be released to thousands of online users. Furthermore, since information is not screened before being posted, much of the information provided by Neogeographers may be private, causing harmful effects to the person with disclosed information. It can potentially be very harmful if the information provided goes beyond being informative.

I don't think that Neogeography will never be able to replace GIS. Neogeography provides the data and creates tools that GIS experts are then able to analyze and support. However, they are closely related and analogous to other information sharing such as journalism compared to blogging. Both GIS and Neogeography have a lot to learn from each other.

GIS # 2

1     1. What is the name of the quadrangle?

Beverly Hills, CA

       2. What are the names of the adjacent quadrangles?

Canoga Park , Van Nuys, Burbank, Topanga, Hollywood, Venice, and Inglewood

3. When was the quadrangle first created?

It was created in 1966.

      4. What datum was used to create your map?

National American Datum of 1929, North American Datum of 1927(NAD 27), North American Datum of 1983(NAD 83).

5. What is the scale of the map?

The scale 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?

The meters on the ground= 5 x 24,000 = 120,000 cm= 1200 m (1m =100cm)

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

The inches on the ground= 5 x 24,000 = 120,000 inches= 1.8939miles

c) one mile on the ground is equivalent to how many inches on the map?

1 mile =63360 inches

63360/24000=2.64 inches on the map

1 mile on the ground is equal to 2.64 inches on the map.

d) three kilometers on the ground is equivalent to how many centimeters on the map?

3 km= 3000 m = 300,000 cm

300,000/24,000 =12.5 cm on the map

Three kilometers on the ground is equal to 12.5cm on the map.

7. What is the contour interval on your map?

It is 20 feet.

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

a) the Public Affairs Building;

N 34°4'40", W 118 °26'15"

N34.0778 , W 118.4375°

b) the tip of Santa Monica pier;

N 34 °0'40", W 118°30'0"

N34.0111°, W118.5°

c) the Upper Franklin Canyon Reservoir;

N 34°6'15", W 118°24'40"

N34.1042°, W118.4111°

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

a) Greystone Mansion

560 feet =170.688m

b) Woodlawn Cemetery

140 feet =42.672m                      

c) Crestwood Hills Park

600~650 feet = 182.88~198.12m

10. What is the UTM zone of the map?

UTM zone 11.

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

3763000m N and 361500m E

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

1000 x 1000 =1000000 square meters

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

14. What is the magnetic declination of the map?

14˚ E

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

From the North to the South.

16. Crop out (i.e., cut and paste) UCLA from the map and include it as a graphic on your blog.

This is a map for my country which is South Korea. From the map Korea an East Asian geographic region that is currently divided into two separate sovereign states - North and South Korea.

The point of star is a National capital which is Seoul. Also, we can know a lot of lines, such as a red  lines for a car and black lines for a train. People can know many information such as road lines and locations of various cities from the map. I am interested in the map because of my country!!

This is a old map for Korea which name is Daedongyeojido. This is a map of Korea the famed cartographer Kim Jeongho made in 1861. Based on a scientific survey of the land and reduced to a scale of one to 160,000, it is by far the most accurate and detailed map made during the Joseon Kingdom (1392-1910). The map comprises 22 woodblock-printed panels, each covering an area of 32km east to west and 48km north to south. The panels unfold to form a complete map of Korea 3m wide and 7m long. With writing a dot on the road line every 10 miles, it indicates the distance. And it has a supplement explaining on the purpose of compilation and the principle of making this map. The outstanding feature of this map is the accuracy. This map had not only an old history of my country but also It was a first map for my country, so I am interested in the map!!

This is a map for my school which is UCLA. There are a lot of buildings in the map, so people can know locations of various buildings. Easy to find buildings from the map. Also, a lot of parking lots are there, so many visitors can find where to park easy from the map. Also, people can get a direction to go to the school because there are a lot of roads and its name. Besides, visitors can know structures of UCLA campus. The map is very helpful for everyone who want to visit the school.

This is a map for the United States. The map had various colors. For example, orange and brown colors are a desert area. A desert is a landscape or region that receives an extremely low amount of precipitation, less than enough to support growth of most plants. Green is a is a fertile area with enough water to support trees and plants. Also, we can check a lot of rivers for blue lines in the map, and we can also notice various areas, such as a green belt, a mountainous, a forest area, higher places and lower places from various colors of the map. Besides, we can see various cities. This map is a very helpful for everyone because they can enjoy the prospect of the whole country, so I am interested in the map!!
