During the past decade, many actual and potential applications for remote sensing technology have been determined. This past year has seen a tremendous amount of interest generated in the application of remote sensing to problem related to land-use. A key element in applying remote sensing to land-use studies involves accurate identification of basic and vegetative cover types. In work with automatic data processing (UP) techniques it is found that as information requirements become more specific, the analysis task becomes more complex. In dealing with many problems involving automatic mapping of vegetative cover types conditions, one finds that an analysis sequence similar to that shown in Figure 1 must be pursued. As is indicated, there are many possible categories of basic cover types, and within the "vegetation" category there are many potential subgroups. Once a particular species has been identified, there are many interrelated factors affecting the potential yield of that crop. Of course, the crop yield is of considerable importance to 8 large number of "users", but since yield cannot be measured directly from remote distances, the factors related to yield and condition of the crop must be determined.
