ABSTRACT 
One important key to the economic development of the ISLAMIC REPUBLIC OF 
IRAN and to the simultaneous protection of its enviroment and its productive 
capacity is the ongoing assesment of state of changes in its rich array of 
land resources. The country of IRAN lies in semi-arid region of S.W Asia. It 
has a total area of 165 million hectares. Due to steady increase in village 
population which has resulted in demand for more arable land,the area of 
forest and rangeland has decreased drasticaly. Over 80% of natural resorcesof 
contry including forest ,range and desert are managing by FRO (Forest &Range 
Organization) which are consider of govermental properties.But the aggerssion 
of nomads and native peopel to occupy these land for cultivation and animal 
feeding are serious problem and make some changes in area. 
To monitoring and regestering these changes the only tool,is field surveying 
which requiers time consumption ‚more manpower,high expences. In recent 
years with relation of severe stae of natural resources degradation ,the 
requirements for up-date information on land characterstics such as type 
,conditon, location value ,specially ownership or land 
tenure,productivity,changes and damages to environment has become quite 
evident. 
It is clear that an itegrated land resources informatoin system,and associated 
technology like modern Remote Sensing sequencial satellite data with 
integration of GIS is one realastic way of meeting these data requierments and 
other needs in future.But still,for small area less than hectar these system can 
not be used properly ,in additon the incompatible of GIS files (vector) and RS 
files (raster) are another case that makes useres dissatisfy ,even for those 
who are using two compatible software . 
This paper is two case study in SHAROD and CHALUS incentral and north part 
of Iran,that shows application of this new technology can be used for whole 
country to achive the up-dated maps in a short time with high accuracy in 
reconnaissance and semi-detail survey.
