Web-based Exercise #6:
Spatial Statistics and Analysis.
1. Overview
Estimated Time: 4 hours
Grading: 8 points total.
Learning Goal:
This exercise will introduce basic concepts of Geovisualization and spatial
statistical analysis. After finishing this exercise, the students should be able
to learn the most common spatial data analysis techniques in the context of
exploratory data analysis environment.
Platforms: PC, Mac, or UNIX.
Due Day: May 3
at 2:00pm.
You
should upload your lab answers to the Blackboard ( http://blackboard.sdsu.edu )
by the due date. We will use the Timestamp on your documents
in the Blackboard to check if your assignment is late or not.
(In your
upload file, please use this title: [GEOG104-LAB-#-[Your
name].doc (or txt or pdf). Please write down your answers in MS
Word or WordPAD or other word processing software. Please always save a
local backup copy of your own answers.)
2. GeoDa Tool for Spatial Analysis.
Dr. Luc Anselin, the director of the Center for Spatial Data Science
at the University of Chicago, has been working on the development of theories and
computer-based tools for spatial statistics for several decades. As one of his
major contribution, GeoDa
http://geodacenter.github.io/
is a typical spatial statistical analysis package devoted to the discovery of
spatial patterns embedded in the geographical data. Please visit the GeoData
web pages
http://geodacenter.github.io/ .
To to the GeoDa website and download the GeoDa Software to
your local computer. (Windows, or Mac, or Linux).
Install the GeoData into your local computer.
Go to this "Basic Mapping" web page to learn the
basic mapping functions in GeoDa.
Please answer the following questions AFTER you
finish this on-line tutorial.
Q2: What is a "quantile map"? What is
the common problem with quantile maps in this exercise? What is the
solution provided by GeoDa?
Q3: What is a "natural breaks map" ?
Who created the methods for the natural break maps?
Q4: What is a "equal interval map"?
What did you see the data distribution in the Histograph window?
What happen if you can the "Choose interval" from 4 to 20?
Please provide a screen shot of the Histogram window with "20"
intervals?
Q5: What is a Box map? What are
the advantages of using a Box map?
Q6: What is a conditional map? What is the
value of creating a conditional map?
Q7: What are the major parameters used in an
animation map? What is the difference between "cumulative" vs.
"not cumulative" animation map?
Q8: Select another sample data in GeoDa
and conduct a few diffreent maps. Explain which sample data did
you choose. Save one map as a PNG format and submit it to
the Blackboard (along with your report).
