ArcGIS ArcView 9.1 Homework Exercise #3
Assigned: October 19
Due: November 4, 2005 by 5
p.m. [Note that this deadline has been
extended from the one listed in the syllabus]
Use ArcGIS ArcView 9.1 software to accomplish the following GIS
tasks and to answer the following questions. You will need to
have completed Chapters 1-6 and 8-9 (including the tutorials) in Getting
to Know ArcGIS Desktop in order to do this exercise efficiently and
effectively. This exercise will require the use of many of the
same skills as used in Exercises #1 and #2, plus new ones covered in
Chapters 8 and 9, the EXCEL (American FactFinder) online tutorial,
and/or discussed in class. You will be using the datasets
available on the student i: drive. The specific files to be used
will be listed with each problem. These files will need to
be used on the i: drive or copied onto a portable storage medium that
is large enough to hold the files; I'll try to make the files for each
problem small enough to fit onto a floppy disk, but you may need a
different diskette for each problem. Your map documents must be
stored on a portable
storage medium so that they can be turned in for grading. Think
carefully
about how your data files are being accessed in the map documents (the
paths
to where the data is stored); the instructor needs to have access to
these
same paths to be able to open successfully the map documents. You
may also send me the files as attachments to an e-mail; if you do, give
me very specific PATH instructions for where I should load them on my
C: or L: to be able to access all the files required in the map
documents.
Problem 1 [20 points]
On the i: drive in the \ziehr\OK-data\ folder use the following
datasets for this problem: OKCNTYD (shapefile and associated
index and data files), Commuting (attribute .dbf), Commuting-Metadata
(.pdf file with information explaining the variables in the Commuting
file). Explore your datasets carefully; understand the data with
which you will be working.
Assume that you are studying commuting to work within Oklahoma.
Create two maps.
Map 1. You are interested in showing how counties compare
in the percentage of their workers who worked in Oklahoma but
commuted outside their county of
residence in 2000. To assist in this
study accomplish the following:
- Create a data frame with an appropriate title
- Join Commuting.dbf to OKCNTYD
- Created a graduated colors map of the appropriate variable
- Use an appropriate number of classes and classification method
- Place your map in a Layout with appropriate title, legend, and
scale
- Print out the Layout
- Strive for cartographic excellence
Map 2. You are interested in showing how counties compare
in the percentage of their workers who commuted outside of Oklahoma
to work in 2000. To assist in this study accomplish the
following:
- Create a data frame with an appropriate title
- Join Commuting.dbf to OKCNTYD
- Create a graduated colors map of the appropriate variable
- Use an appropriate number of classes and classification method
- Place your map in a Layout with appropriate title, legend, and
scale
- Print out the Layout
- Strive for cartographic excellence
The maps that you create will be in stored in a map document (.mxd)
on a portable storage medium (or e-mailed to me)--you must
use the following filename for your map document: yourlastname-hw3-prob1.mxd
(of course, use your actual last name in place of yourlastname).
Problem 2 [10 points]
On the i: drive in the \ziehr\OK-data\ folder use the following
datasets for this problem: OKCNTYD (shapefile and associated
index and data files) and oksmallcities (shapefile and associated index
and data files). Explore your datasets carefully; understand the
data with which
you will be working.
Create a map document that accomplishes the following:
- Create a data frame with an appropriate title
- Create hyperlinks to the WWW homepages of all small cities with
1998 populations between 30,000 and 50,000
- Use Select by Attribute and Select by Location to select all of
the counties that contain small cities that have 1998 populations
between 15,000 and 35,000; be sure these counties are shown as selected
in your map
document
The map that you create will be in stored in a map document (.mxd)
on a portable storage medium (or e-mailed to me)--you must
use the following filename for your map document: yourlastname-hw3-prob2.mxd
(of course, use your actual last name in place of yourlastname).
Problem 3 [20 points]
On the i: drive in the \ziehr\OK-data\ folder use the following
datasets for this problem: OKCNTYD (shapefile and associated
index and data files). Explore your datasets carefully;
understand the data with which you will be working. You will
also be downloading a file of census data from the U.S. Census Bureau's
American FactFinder website.
Accomplish the following:
- Download a file containing a variable of your choice (the only
exception you may NOT use any of the commuting data used in Problem 1
above) from American FactFinder website for the 77 counties of
Oklahoma. This file will
need to be put into the proper form to be joined to the OKCNTYD
attribute
table. The American FactFinder website can be found at http://factfinder.census.gov/
. Be sure to provide me with the datafile that will be joined.
Initial instructions for how to download files can be found at <http://arapaho.nsuok.edu/~ziehr/courses/geog3813/Data_via_American_FactFinder-Fall2005.html>.
- Create a thematic map of your downloaded variable that emphasizes
how the counties of Oklahoma compare
to the average value for this variable (this last phrase is
clue to the class ranges that you should use).
- Display this map in a layout with appropriate title and legend.
The map that you create will be in stored in a map document (.mxd)
on a portable storage medium (or e-mailed to me)--you must
use the following filename for your map document: yourlastname-hw3-prob3.mxd
(of course, use your actual last name in place of yourlastname).
