It's not magic. All it takes is a basic understanding of the underlying concepts, the right tools, and the data itself. We have tried to cover the conceptual aspects elsewhere in this site, especially in the resource section. In this section, we provide information on where to obtain remote sensing data and the tools necessary to display, manipulate, and analyze those data.

Yes, I said free. We have seven-band, 512x512, thirty-meter resolution data sets from the Landsat Thematic Mapper and a step-by-step procedure for viewing and analyzing them using a freeware application that is available for both Macintosh and PC computers. Download the images and the software and you can be doing remote sensing today! |

Remote sensing satellites have been collecting observations of the Earth and space for many years. There are several major NASA and other government archives of Earth and space data, as well as several commercial remote sensing firms that offer value-added products. |

Remote sensing display and analysis software is now available for almost every type of computer system, including those found in homes and schools. We have included summaries of a few popular packages, both commercial and in the public domain, as well as links to where to obtain more information and the actual software. |
