Welcome to the Introduction to Global Change Class's

Remote Sensing Package Home Page

This remote sensing package has three parts:

  1. Images Used in Lecture,
  2. Lab 8 - Introduction to Remote Sensing, Photometry, and Ground-Truth,
  3. Lab 9 - Remote Sensing - Case Studies Using Satellite Images

The first part is the lecture that will be taught October 19th. It will give you a general background of the meaning of ``remote sensing'' and will introduce you to the many uses of remote sensing data at both local and global scales.

The second part takes place during the laboratory period of October 19th. The purpose of this part of the module is to get ``hands-on'' experience in the ``ground-truthing'' process. We will be using an exotech radiometer to measure the reflectance values of different surfaces (such as leaves, grass, concrete...) in a fifteen meter plot. We will compare our measurements to those taken by a SPOT satellite of the same twenty meter plot. We will meet in Harshbarger 203 (the lab classroom).

The third part takes place during the laboratory period of October 26. This lab will focus on the use of satellite images to study areas of deforestation and desertification. We will use the data collected the week before to calculate NDVI (Normalized Difference Vegetation Index) for our plot and compare this to the satellite's value. We also will study in detail images of southeastern Arizona and Brazil.

This third part of the module is where you, the students, can choose what you'd like to study!

In lecture on Thursday, October 19th, I will ask you to take out a note card at the end of the class period. On that note card you will write two things:

  1. a place that you would like to study (i.e. Russia, the Himalaya Mountains, South America - anywhere in the world!) and
  2. a process that you would like to study, i.e. volcanism, coastal erosion, flooding, the enlargement of the ozone hole). The process that you choose does not have to be related to the place that you choose.
I will do my utmost to find images to meet your requests. After finishing your study of NDVI and the images of Arizona and Brazil, you will choose another image from the list that I will provide to study. I will give you guided questions to aid you in your analysis.
The rest of this home page is devoted to the images used in the lecture and the labs. The lecture notes and illustrations and a color copy of the southeastern Arizona image will be given to you as handouts in lecture and in your lab packets. The purpose of giving you the images on a WWW home page is so that you can have the convenience of viewing these images in the Global Change Computer Lab and from elsewhere on campus without the incredible expense of making color copies. Creating a home page for the images also saves space on the hard drives of the Macintoshes in the Global Change Computer Lab (a most treasured commodity!).

PLEASE, do not copy any of these figures or images without seeing me first! Some of this material is copy-righted!


Section I: Images Used in Lecture

(Text captions including the sources (human institutes and satellites) will be added soon!)

  1. Kliuchevskoi Volcano, Russia
  2. Radiation Budget I
  3. Radiation Budget II
  4. Albedo1
  5. Albedo2
  6. Ozone Hole Images
  7. Ozone Measurements Graph
  8. Weather Image
  9. Gulf of Mexico Sea Surface Temperature
  10. El Niño
  11. New Orleans Radar Image
  12. Flooded Manaus River, Brazil
  13. Global NDVI
  14. NDVI for Africa

Section II: Lab 8 - Introduction to Remote Sensing, Photometry and Ground-Truth

The ''Global NDVI'' and ''NDVI for Africa'' images listed above are very relevant to this lab. How does the southwestern U.S. compare to the Amazon River Basin of South America? Northern Africa?


Section III: Lab 9 - Remote Sensing - Case Studies Using Satellite Images

In this lab we will study images of southeastern Arizona, Brazil, and the image of your choice from the list under Part 3 below. The lab handout will list the study questions for Arizona's and Brazil's images and the general questions for Part 3. Specific questions for each of the images in Part 3 will be in the "caption" to each image.

The following images are used in Parts 1 and 2 of Lab 9:

  1. Infrared Image of Southeastern Arizona,Legend
  2. Rondonia, Brazil, 1975 and 1986 Images
  3. Southern Rondonia Image
  4. Deforestation of the Amazon River Basin Statistics Table

Part 3: Choose one of the images listed below to describe in an e-mail letter to your classmates. Be certain to look at the ``caption'' next to each image. The captions include summaries describing the images and list discussion questions. To get full credit for the lab assignment, you must answer the discussion questions listed in the captions and give the following information: 1) the ground location of the image, 2) the type of image (i.e. infrared or radar), 3) the purpose of the image (i.e. to study deforestation in the Amazon River Basin), 4) what you thought was the most interesting feature in the image, and 5) what you learned from the image that you would not have been able to learn if you had been standing on the ground (or swimming in the water!) and viewing the region through only your eyes rather than looking down at this region from a high altitude.

  3. ''Greeness of Australia'' videos. The videos of seasonal vegetation changes over Australia are located at the following address: http://kaos.erin.gov.au/sat_pics/ndvi.html. See Michelle for more explicit instructions if you are interested in exploring these images.
