Abstract: The aim of this research was to locate suitable areas for economic crops of sesame based on Geographic Information System (GIS) and Physical Land Evaluation Model in Chi watershed, North-east of Thailand. The authors used decision tools or rules to locate suitable areas for economic crops plantation by analyzing six variables from physical evaluation model (S), (W), (R), (L), (SA), and (SL). These six factors were analyzed by using overlay function technique including union and intersect scheme. The variables then were determined their score via Physical Land Evaluation Model. The results of this work found that areas for sesame plantation included high, moderate, low and non suitable areas, which accounted for 30.47%, 19.61%, 8.92% and 1.66%, respectively.
Keywords: Suitable Areas, Economic Crops Plantation, GIS, Physical Land Evaluation.
