Identification and Separation of Formic Units at Gavkhoni Play

In geomorphology there are variety methods to separate and identify the formic units. One of them is Hierarchy Theory. In this paper study area is Gavkhoni Playa. The purpose of this study is to identify separation and display formic units by using GIS and RS techniques hierarchically. To achieve this aims، topographic maps (1:25000، 1:50000)، geological map (1:250000)، satellite image of sensor ETM of Landsat 7 and field observations were used. To earn geomorphic map it is necessary to produce formic unit''s maps (land view، land feature and land forms and lithology map). The results indicate Gavkhoni Playa is a geomorphic landscape. This unit composed of some landviews. Every land view consists of land feathers and geoforms. The results indicate the ability of RS and GIS Techniques to identify units and produce geomorphic map. The map helps us to evaluate land suitability and environmental management of study area.
