Which end (color) of the spectrum has the shortest wavelength? Wavelengths shorter than this end fall into the _______? Wavelengths longer than this end fall into the _________?
Read the section on Remote Sensing. In particular, read the sections on the electromagnetic spectrum, energy interactions and digital images. These three short summaries will provide a good background for the resources that follow. Before you leave this site, look though one or two of the sets of images in the Gallery.

NASA has been a leader in promoting a greater understanding the Earth and other bodies through remote sensing. The Observatorium is another NASA site with a good introduction to remote sensing basics. The Search for Ubar is a particularly well-done analysis of one application of remote sensing in archaeology.
Briefly describe your reaction to the Ubar study. I am curious, is this format (the Internet) one which is satisfactory for you? That is, are you satisfied to read material on the screen or do you feel the need to make a hard copy?
