Remote sensing is the art and science of acquiring information about the earth and its environment using sensors such as cameras, scanners and radar mounted in aircraft and spacecraft.  The National Aeronautics and Space Administration (NASA), working in cooperation with the Western Governor’s Association, the National States Geographic Information Council and other organizations, has initiated a new program to assist state and local governments in exploring the potential of remote sensing.  This web page was developed by James Merchant and James Lacy, University of Nebraska-Lincoln, in support of a workshop designed to provide basic information on remote sensing technology and applications for those working in state and local governments.  It is intended to provide a selective guide to important concepts and data sources, and give direction to those who may wish to independently learn more about remote sensing.
