Abstract: In Mediterranean regions there is little experience in using GIS as an aid to land evaluation. This paper reports a project in Greece which investigated the usefulness of such technology, Particular emphasis was also given to comparing the results of land evaluation using Boolean and fuzzy set methodologies. The need was to produce the results as quickly and efficiently as possible to aid agricultural planning. By using a GIS, a series of single factor and land evaluation maps was produced for a range of crops; a land suitability map for receipt of sewage was also derived. A comparison of results from using Boolean and fuzzy set methodologies highlighted the advantages of the latter, although critical decisions are required on choice of membership functions and weights which have a major effect on the results.
