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, MODIS, ASTER, 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 a short HTML file to provide text and display for each of the images—see sample.

Begin your search with the EarthExplorer or Glovis. See also NASA imagery.

<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>

You may use the Windows "Notepad" or "Wordpad" 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. Pacific coast of eastern Asia.

  2. Irrigated agriculture, center-pivot or canal/ditch system from the Middle East.

  3. A large city in central Europe (Berlin, Warsaw, etc.).

  4. Large lake or river from Australia.

  5. Southern Atlantic region—any coastal view of South America or Africa south of the Equator.

  6. Sea ice or glacier in Antarctic region.

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

  8. Tropical forest from Indonesia or Indochina region.

  9. Desert scene from central Asia.

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

Note: Search for primary (original) imagery with metadata from government agencies (U.S. or elsewhere). Do not utilize TerraServer, Google Earth or similar commercial sources for this lab exercise. You may not use any images from ESU webpages.
