GEOG 303/403 - Lab 5
Work through Chapters 9 and 10. Use ArcCatalog to copy the data you will need to your personal drive. Remember to always work off your own drive! As you work through these chapters, remember that your data is on your drive, not wherever the book points you.
Provide brief answers to the following (must be typed):
1) Chapter 9 is, effectively, your introduction to databases. In other words, handling columns and rows of data. Work through the chapter, then print the final map (step 29).
2) How might you improve this analysis (given the same dataset)? What are some of the weaknesses of the book's analysis? Strengths?
On to Chapter 10: you will note that three of the four spatial relationships mentioned as being searchable options are topologic. The one that isn't is distance. Also note that what they are calling a "spatial join" in this chapter is the same thing as the topologic overlays that we discussed in class.
3) After working through this chapter, you think "WOW, what a powerful tool" and want to run a separate analysis. First, grab the modified dataset (EVERY point in this shapefile is a shopping centers - I added a bunch for this lab) from J:\geog303\lab5\. Then, whomp through the following analysis and print your final map:
Find all places (shopping centers) that are within 2 miles of a freeway AND are in neighborhoods (use the census data that has all the demographic data) that have a high population, but a low income. You (yes, you) determine what (in this area) would be considered high pop and low income. List your decision (and the logic behind it) on your final map. To help you out, try looking at the histograms (classification menu) - that would be a good way to get a handle on the distribution of incomes/population. Give the map a title which reflects what this analysis might be searching for (guess).
REMEMBER - whenever turning in a map, be sure the 'standard stuff' is on the map: neatline, legend, title, scale bar, and north arrow.
