GEO 420 Project Land Use/Land Cover Analysis of S. California
General Idea of Projects
The scenario
You are working for either a private company,
or government agency as a RS/DIP analyst.
Your boss has given you the lead responsibility
on a project performing a Land Use/Land Cover
Analysis of an area in S. California.
The final report will be sent to the local County
Board of Supervisors for use in land use
planning decisions.
• You want to look at land use changes in your study
area over time, so you are comparing two different
years.
• Your study area (subscene) should be roughly 50 x 50
miles.
• The report is to be 4 pages of text (not including title
page, abstract or references), plus figures and images.
The analyses for your 2 different years that you need to
undertake and discuss (with figures) in your report includes:
1.2 different pairs of color band ratio composites (year 1, year
2)
For example – A. NIR Composite for year 1 and year 2,
B. True Color Composite for year 1 and year 2
2. A pair of unsupervised classifications (year 1, year 2)
3. A pair of supervised classifications (year 1, year 2)
4. A pair of NDVI indices (year 1, year 2)
5. Table 1: An NDVI comparison showing the % coverage of
the different vegetation categories with a column showing the
+- changes between years.
Year 1 Year 2 %Change
Heavy Veg. 30% 25% -5%
Moderate Veg. 30% 35% +5%
No Veg. 40% 40% 0%
6. Table 2: A Supervised Classification comparison showing
the % change in land cover results with a column showing the
+- changes between years.
Year 1 Year 2 %Change
Forest 16% 12% -4%
Chaparral 25% 19% -6%
Urban 33% 40% +7%
Bare Soil 25% 28% +8%
Water 1% 1% 0%
7. A pair of pie charts (or other graphic)
showing percent land cover results of final
supervised classifications (Year1 & Year 2
results from table above).
8. Ground Truth Table of information for your 6
sites with 1 – 2 photographs that you took at
each of your 6 sites.
9. Choose 1 – 2 of the 4 - 5 Online figures (air
photos, maps) that you used in your ground
truth exercise.

Written Report
Your report should be structured with the following
sections:
1. Title Page
2. Abstract
3. Introduction/Background
4. Data & Methods
5. Results & Conclusions
6. References
7. All Figures/Photos/Tables
Written Report
• All figures, tables, photos must be numbered and captioned.
• All figures must be referenced and discussed within the text or they will not be considered part of the paper.
• Report: 4 in length (not incl. title page, abstract, references page, or figures).
• All figures go at end of document (print in color where appropriate).
Written Report
• Introduction/Background. Begin with a thesis
statement of what the project is about, and then should
proceed to introduce it to the uninformed. Do not
assume that your reader is familiar with your project or
related topics (i.e., remote sensing or DIP), so do not
get into specifics or too much technical detail in this
section. Describe Study Area.
Thesis Statements
Every paper, no matter how long or short, no matter its
topic--even a book review--has a thesis.
A thesis is a statement of purpose; the thesis gives the
reader some idea, in capsule form, of just what it is that
the writer intends the reader to learn from a particular
piece of writing.
Written Report
• Introduction/Background. Make it comprehensible to an
informed layman (the readers are politicians, not
scientists). Give enough background to enable them to
place your particular research in a context of common
knowledge (~1 ½ pages).
• Include description of study area.
Written Report
• Data & Methods. Now you can get into to the specifics of
the data and the methods of analysis. What are your
data sources, why did you choose the data you are
using, what type of DIP operations have been done to
your data to get it ready for you to analyze? What
analysis methods did you use?, why? (~1 ½ pages).
Written Report
• Results/Conclusions. Describe the results of your
analyses. State what you found, refer to your
figures/tables, etc. while doing so, then explain and
assess the results. This section is often short, but very
important and concisely written. (~1 page).
• References. List a minimum of 5 references (texts,
articles, web pages, ERDAS pdf documents, etc.) these
must be referenced in text!
