Zoning the land-capability of Roudehen for agricultural usage by the OWA1 technique in geographic information system environment

Abstract

One of the most sensitive issues that must be considered in many decisions are environmental factors. Planning for the optimal use of land makes it possible to maintain natural resources for using in future by the Earth too. Locating is one of the most widely used spatial decision-making which can be influenced by many environmental factors. The aim of the locating is to find a set of appropriate spatial options for a particular application. The locating issue is a multi-criteria decision-making problem. In current article, we have used OWA land-capability classification using GIS in order to prepare, evaluate, classify and overlay the layers. We have used six parameters of height, land use, climate, soil, slope and tilt direction for evaluating and categorizing land power. Finally, the areas that indicates the best potential of farming and other classes have been identified.
