Since each model is built by a different evaluator to satisfy local needs , there is no fixed list of land use requirements by which land uses are evaluated, and no fixed list of land characteristics from which land qualities are inferred. Instead, these lists are determined by the evaluator to suit local conditions and objectives. ALES is not by itself an expert system, and does not include by itself any knowledge about land and land use. ALES is a framework within which evaluators can express their own, local, knowledge. The program is highly interactive , and takes advantage of the PC video display and keyboard.
Function keys control most operations.
