The purpose of this paper is to analyze the sensitivity of Geographic Information System outputs to errors in inputs derived from Remotely Sensed Data (RSD). The attention is restricted to outputs of suitability models with "per cell " decisions with gridded Geographic Data Bases(GDB) whose cells are larger than the RSD pixels. The procedure for merging RSD into such GDB's involves classification, registration and aggre-gation. The first two steps introduce errors at individual pixels and the last step tends to compensate for such errors
