| Abstract: | The author outlines a method for extrapolating reference spectral data describing the condition of certain crops obtained for a particular point in time to periods for which reliable remote sensing data are not available. Examination of the correspondence between crop “condition classes,” identified through visual interpretation of aerial imagery, and actual yields/biomass for a number of phases of crop development of winter wheat for several crop years provides basic information for a probability matrix of the condition of a crop at times B, C, and D based on previous conditions at times A, B, and C.
