Introduction to Remote Sensing (sensing from a distance)

Read step 6 first. Then go to: Weather Web Cams - Ohio (http://www.passco.com/ohiobugs.htm) or Earthcam (http://www.earthcam.com/). Discuss with your partner or group what types of information you can know from this view and also what information is limited. Chart a summary of your discussion on the worksheet below.
Go to http://maps.live.com/ Find your school and your home by typing in the address in the search box. Share with your group your observations about how long ago it was taken, what time of year and what time of day. Discuss how you know these things. Record how information available from 2 location from this website is different than from a web cam information and what information is not available.
Go to Google Earth. Zoom in on your school and home. Explore viewing options. Share and chart differences between these images and those on the webcam and the maps.live sites.
See LANDSAT live, or almost live at EarthNow! http://earthnow.usgs.gov/earthnow_app.html?sessionId=f1b13e89aca30c986a332751482bf58120197
Share with the class what you learned that was new or interesting and one way remotely sensed images can be applied to the subject of your course.
Go to the following sites for a basic introduction to satellite imagining. Answer accompaning questions on the worksheet. See the annotated resources for more extensive information.

To learn about Landsat satellite images go to: http://geology.com/satellite/landsat-images.shtml. Answer worksheet questions.
To see how different light colors mix, go to http://biodiversityinformatics.amnh.org/tool.php?content_id=142. Move the sliders back and forth to see color additions. Answer the questions on the worksheet.
LANDSAT: How does it work? http://landsat.gsfc.nasa.gov/education/compositor/
To understand the relationship between band wavelengths and common surface features, go to http://biodiversityinformatics.amnh.org/tool.php?content_id=145 Set the satellite mode for LANDSAT ETM + widths. Select Key features cheat grass, asphalt, concrete, snow, and tap water. Identify the best band to use to tell the difference between the various features listed on the worksheet chart by finding the band where the features differ the most.
Go to Satellite information at http://science.nasa.gov/Realtime/JTrack/Spacecraft.html Click on J-TRACK 3D . Find Landsat 5 and record where it is located at the present time. Browse, views, satellite, and options.
Optional: For further information on satellite images go to http://biodiversityinformatics.amnh.org/index.php?section=rsr_tools and click on each interactive tool.
