Summary:
Since the development of remote sensing nearly 60 years ago, there have been many applications for agriculture. Some have proved effective, while others have not succeeded in assisting farmers with problem solving. Profit margins for individual farmers are typically slim; therefore, farmers are likely to take seriously any technology advances that will help increase those margins. So far the use of remote sensing data has proven most economical for the high value crops where the risks are greater per acre. Remote sensing has not been perceived as cost-effective for Midwest crops where weather is the greatest variable and therefore not manageable. Recent advances in the spatial, spectral and temporal resolution of remote sensing (Johannsen et al., 1998) as well as potential positive changes in cost and availability of remotely sensed data may make it a profitable tool for more farmers. There are some practical applications of remote sensing that are often overlooked by many farmers and consultants. The purpose of this Guideline is to highlight those applications.
