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!
