This study used Geographic Information System (GIS)-based multi criteria evaluation and remote sensing to delineate locations for brackish water shrimp pond suitability in the north coast of Tuban, Indonesia. An Analytical Hierarchy Process was conducted to obtain the weight of thematic layers. The thematic layers used consisted of soil characteristics theme (pH, texture and base saturation), topographic theme ( elevation and slope), water quality theme (salinity, water pH, dissolved oxygen, and temperature) and infrastructure theme (distance to market and distance to main road). A weighted overlay in GIS was done to delineate the suitable land for brackish water shrimp pond. The result indicated that there are areas of highly suitable and suitable for brackish water shrimp pond. Land cover map, interpreted from the 2014 SPOT 5 satellite imagery was used to define the constraints ofland utilization. A recommendation map for brackish water shrimp pond area land use planning could then be done by overlaying suitability map and land use map.
