GEOG 303 - Lab 4
Work through Chapters 7 and 8. Use ArcCatalog to copy the data you will need to your /flash disk. 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 7 mucked about with labels. Yet another important sort of thing if you want your maps to make sense. You played with a number of different ways of setting/positioning/placing the labels. What are the advantages/disadvantages of each method (to give some hints, this would be things like automatic vs manual placement, different locations, wrapping text, etc).
Onto chapter 8. Now we stop playing with the interface and start playing with the data. In this case, querying and selecting data from both maps and their associated attribute files.
2) Give an example (NOT from this lab) of when you would want to do a attribute query as opposed to a map query. Explain your logic. Translation: why would you do an attribute query instead of a spatial query? Give an example.
3) Give an example (NOT from this lab) of when you would want to do a map query as opposed to a attribute query. Explain your logic. Translation: why would you do an spatial query instead of a attribute query? Give an example.
4) Give an example (NOT from this lab) of when you would want to use the hyperlink option. Explain your logic.
5) Open a new (blank) ArcMap file and add the US county datafile (found on J:\geog303\lab4\). Run the following query. The query is to find all the counties with areas greater than 2000 and populations per square mile that are greater than 100. In short, this locates the largest and most densely populated counties in the US. Create a map which somehow highlights these counties and includes (preferably as a table embedded on the map): county name, state name, area, and population per square mile. Add the usual map layout elements (N arrow, etc.).
