Dr. Crews-Meyer's presentation covers the fundamentals of remote sensing of the environment, with particular attention to multi-spectral optical satellite systems. The number of satellites collecting information about the global environment is rapidly increasing. Much of this information is publicly available for little to no charge. But how can people make use of this information? The principles of remote sensing are explained through analogies to a picture taken with an everyday camera. Numerous images of the Austin area are used to illustrate what a remote sensing analyst "sees" in Austin, and how that vision compares to what we see everyday as we walk around our homes, schools, and businesses.
