GIS for Week 2 (2/1)

By Tuesday, February 1, at 1 PM, please do the following exercises:

  1. On whichever Windows computer you're using, you'll probably need to again map the network drive \\storage\colq-32 (it turns out that shortcut you stored on your U: drive will only work on the exact same computer as before).
    • Once you have mapped this drive, inside your own folder, create a folder named “Assignment Week 2”.
  2. Using the map that you created in class this past Tuesday, pick up where we left off:
    1. Open the map you created in class and complete the exercise in the handout entitled “Adding and Symbolizing an Image Layer”, which is also on this web site:
      http://www.ats.amherst.edu/software/gis/constructing_sharing_maps/#AddingandSymbolizinganImageLayer
      To work with your data, you may need to make a new connection from within ArcGIS to the network drive \\storage\colq-32 .
    2. Change the symbology of the layer States to be Features using a Single Symbol with no fill color and a thick, bright red outline, as shown in the exercise above.
    3. Center the United States in the view, as shown (hint: right-click on the States layer to bring up its contextual menu, and one of the items there does the job).
    4. Save the map.
    5. Menu File and then Export Map…, and in the resulting dialog locate the menu Save as Type: and choose PNG; navigate to your folder “Assignment Week 2”  and then click the button Save.
  3. Investigate some basic demographic characteristics of Boston-area cities and towns:
    1. Create a new map (you could, for example, click on the button  New Map File). Make sure it is using relative pathnames, and save it in your folder  “Assignment Week 2”. Also click the Save button after each step below!
    2. Investigate the total population:
      1. Add this layer to your map (you will probably need a new connection):
              \\storage\colq-32\@Data\Assignment Week 2\Boston-Area Census 2000.lyr
        (note .lyr not .shp). This layer contains all of the cities and towns near Cambridge, along with selected census information.
      2. Label the cities and towns on the map; make sure that they are readable with the symbologies you use below.
      3. Symbolize the map using the Quantity Total Population. In this case, use a Dot-Density symbology with a dot value of 2000.
      4. Save a PNG file as described above in step 2(e).
      5. Which locations appear to have the highest densities? Write your answer in a text file and save it in the same folder as your saved pictures.
    3. Investigate the Black population:
      1. Right-click on the layer you created in step 3(b) and copy it; then menu Edit and Paste to create a new layer with the same data. Turn off one of the two layers.
      2. Change the symbology of the new layer using the Quantity % Black = Black Population / Total Population and the Graduated Colors symbology.
      3. Save a PNG file as described above in step 2(e).
      4. Which locations appear to have the largest proportion of Blacks? Write your answer as described in 3(b)(v).
    4. Investigate the Hispanic and Latino population:
      1. Right-click on the layer you created in step 3(b) and copy it; then menu Edit and Paste to create a new layer with the same data. Turn off one of the two layers.
      2. Change the symbology of the new layer using the Quantity % Hispanic-Latino = Hispanic-Latino Population / Total Population and the Graduated Colors symbology.
      3. Save a PNG file as described above in step 2(e).
      4. Which locations appear to have the largest proportion of Hispanics and Latinos? Write your answer as described in 3(b)(v).
    5. Investigate families with children:
      1. Right-click on the layer you created in step 3(b) and copy it; then menu Edit and Paste to create a new layer with the same data. Turn off one of the two layers.
      2. Change the symbology of the new layer using a Chart, in particular a Pie Chart. Use the three categories of Families with children: Married Couples, Single-Parent (Male), and Single-Parent (Female).
      3. Save a PNG file as described above in step 2(e).
      4. Which locations appear to have the largest proportion of single-parent families? Write your answer as described in  3(b)(v).
