This paper outlines a method for estimating computer processing times and costs incurred in producing information products from digital remotely sensed data. The method accounts for both computation and overhead, and it may be applied to any serial computer. We apply the method to estimate the cost and computer time involved in producing Level II Land Use and Vegetative Cover Maps for a five-state, mid-western region. Our results show that the amount of data to be processed overloads some example computer systems, but that the processing is feasible on others.
