A major problem for many decision-makers is the lack of reliable information on which to base decisions. This is particularly true for the extent and location of as well as changes in such natural resources as forests, rangeland, agricultural fields and water bodies. A very useful data source in providing such information is the Landsat orbiting satellites. These satellites have been repetitively collecting images of essentially the entire earth's surface since 1972. These images are readily available, inexpensive, useable and can provide exceptional resource information. Examples are presented on the use of this data for a variety of resource analyses.
