A remote sensing evaluation for agronomic land use mapping in Tehran Province, Iran

It has become essential to prepare land use maps because these are recognized as necessary tools for the preparation of land capability, land classification and land suitability maps which in turn provide guidelines for the regional planning, development and future orientation of agriculture in the regional system. The principal objective of this study is to identify, demarcate and map agricultural land use categories of Tehran province on basis of remote sensing survey technique. In this research, Landsat ETM images of July 2006 were used to expose the use of remote sensing technique in order to produce current land use map of the study area. Analysis indicates that the major parts of the area comprise rangeland with the total surface area of 1146585 ha. About 102080 ha of the total area was occupied by rock outcrop and forest land. The remaining surface area was under cultivation.
