ES 771 Lab Exercise
REMOTE-SENSING IMAGERY SEARCH

Your assignment is to search World Wide Web sites on Internet in order to locate, describe, and download space-based, remotely sensed images of selected features. The kind of imagery may vary--manned or unmanned space photographs, and satellite images--Landsat, SPOT, AVHRR, Radarsat, Terra, and others. For examples of space imagery see the ESU webpage, Fire and Ice.

For each feature you should note the following information: WWW site URL, kind of image, date of image acquisition, image identification code, and brief description of what is depicted in the image. Use the file "save as..." command to download images to your personal subdirectory. You will make up short HTML files to provide text and display for each of the images--see sample.

Begin your search with the Earth Explorer from the U.S. Geological Survey.

<h1>Multispectral Image of Timbuktu</h1>

The city of Timbuktu is depicted near the center of this scene from Mali, Africa. The image is a multispectral composite that was created from green, red, and infrared bands of the Interquest pushbroom scanner (IPS), 10 m resolution, 21 April, 1994. The image file was acquired from the PanAfrican Remote Sensing Center in Bamako, Mali.<p>

<h1>Next Image, etc.</h1>

You may use the Windows "Notepad" editor to create the HTML ascii text. In this way, you can edit files and see results together. Or you can use another word processor in the "no format" mode.

Locate and download images of these features:

  1. Atlantic coast of South America.

  2. Irrigated agriculture, center-pivot or canal/ditch system from Asia.

  3. A large city in Europe, such as: London, Copenhagen, or Berlin.

  4. Inland sea or large lake from Asia.

  5. Southwestern Pacific region--any view of Australia or New Zealand.

  6. Icebergs from Antarctica or Greenland.

  7. An active volcanic eruption (with smoke, steam, ash) from the northern Pacific region.

  8. Tropical forest from any location.

  9. Marine coastal scene from any portion of Africa.

  10. Large wetland complex--delta, bog, marsh, swamp, etc. Located in a high latitude (>60° N or S).

Note: Do not utilize TerraServer or Google Earth for this lab exercise. You may not use any images from ESU webpages.
