1. Where will you find the data for the labs?
If you are on a new computer the data for the labs will be found under the J: drive. This means that you go to My Computer, then click (j:). If there is no Isis folder go directly to the folder titled “html” then the folder named “courses,” then click on the folder titled “2010spring,” then the folder named “geog.” Once you have navigated to this folder click on the class name, “370,” then “006.” Once you are inside the folder “006” you should be able to see a folder named “data.”
Or, once you have created a shortcut through the M: drive then just go to that drive and click on the folder named “data.”
2. Already done, have a folder automatically.
3. What is the drive letter of your home directory? Where do you save your lab reports?
a. Home directory is on the H:/ drive
b. Save lab reports on either M:/ drive or J:/ drive.
4. Place in an ATN lab where only you can see it?
a. You would save your work in your H:/ drive in your folder named “private.”
5. What would your URL drive be?
a.

7. A layer is a group of information on a GIS map. For example in the picture above, the roads are a layer on the map.
8. A feature is a piece of information within a layer. For example, the names of the roads are features within the roads layer.
9. A large scale map is also known as a fine grain map. It shows a smaller area with more detail. The scale on a large scale map may look like 1/1,000. A small scale map is also known as a coarse grain map. It shows a larger area with less detail. Compared to the large scale map, the scale may be 1/40,000.
10. In arcMap, there is Data view and Layout view. In Data view, all elements like north arrows, scale lines, and road names are hidden. This allows you to focus on and analyze a single set of data. When you are designing, editing or adding more information to a map, you will want to use layout view. This view also allows you to preview what the final product will look like before you print or export it. Layout view also lets you look at all of the data frames in your map instead of just one in the data view.
11. Modify: allows you to see all the parameters associated with the coordinate system.

12. The continental US seems to be smaller in the new projection. Also, the size of Alaska has gotten smaller and the latitude lines are now curved up.
13. False Easting: 0.0
False Northing: 0.0
Central Meridian: -96
Standard Parallel_1: 29.50
Standard Parallel_2: 45.50
Latitude of Origin: 23.0
Liner Unit: Meter

I do not believe that the Equal area projection is a good way to view the entire world. It cuts some countries in half and the map seems to skew more in the southern hemisphere.

Each map shows the world from a different perspective. The Mercator distorts areas in the southern hemisphere including, Africa, Antarctica, and Australia. The Robinson, shrinks areas close to the North Pole including Greenland and Alaska. The Robinson distorts shape in areas to the far west and also shrinks areas in Europe. It also is an odd way to look at the Pacific region because it is split so awkwardly. The GCS seems to distort the US the least and has perpendicular latitude and longitude lines.
