 | Geospatial Lab Exercise
Aerial and Space
Imagery Search |
Your assignment is to search World Wide Web sites on Internet in order to locate and describe aerial or space imagery of selected features. You may utilize pictures from any type of remote sensing instrument--film or digital camera, multispectral scanner, thermal imager, radar system, etc. These images could be acquired from either manned or unmanned platforms--blimp, kite, airplane, satellite, space-shuttle, etc. For each feature you should give the following information--the so-called metadata.
WWW site title and site URL [complete and correct].
Kind of image; type of remote sensing instrument; platform.
Date of acquisition and image identification code.
Brief description of what is depicted in the image.
Begin your search with course resources for GIS and Remote Sensing Data. This Web page provides links to many Web sources for GIS data bases and remotely sensed imagery. Students are encouraged to explore other Web sites for appropriate imagery--see lectures on remote sensing and aerial/space photography.
Focus your search for primary imagery sources from NASA, U.S. Geological Survey, and other governmental or university sites that provide image metadata. Do not utilize TerraServer or Google Earth for this lab exercise; these are secondary sources that do not provide metadata about their images.
Locate and describe these features
- A major city in Asia.
- Transportation network, such as railroad switching yard, highway interchange, or major airport, in Europe.
- A large wetland complex, such as bog, estuary, floodplain or swamp in Africa.
- A large lake or river in Australia.
- A volcano from the southern Pacific region (south of Equator).
- Tropical forest from South America.
- Irrigated farmland from southeastern Asia, including India or Indochina regions.
- Glacier, ice cap or pack ice from the southern hemisphere.
- Smoke from any kind of fire, such as: prairie, agricultural, forest, oil, etc.
- A desert scene from Africa.
Download a digital image of the marked item above.
Note: You may not use any images from any ESU webpages. Confine your search to remotely sensed imagery; do not submit topographic maps or other types of maps.
Turn in via e-mail
- Descriptions for each item (1-10).
- Digital image file for marked item.
