Revealing the physical change of Ardebil City by using LandSat ETM images and MARKOV chain model

The use of satellite imagery can be a very useful tool to describe the
interrelationships between the human environment and the natural environment to help
planners make decisions in complex situations. The process of urban development of
cities is one of the basic needs in management and evaluation. In addition, amount of
growth of cities, the study of changes amount and land use destruction in past years,
and predict these changes in the coming years can help in the correct management and
planning to solve the current problems and future development planning program. In
this regard, this study tends to using Satellite imagery Landsat Tm in 1988 and
Satellite imagery of LandSat ETM in 20011 to assess the physical growth and in order
to expansion of Ardabil. This study is consistent with periods before and after political
centrality of Ardabil. For this order after the satellite image processing, the images
were classified using maximum likelihood method and finally in geographic
information system (GIS) by applying changes function were obtain land use changes.
According to the conducted investigations it was concluded that physical growth of
Ardabil after the political centrality has taken great acceleration, and during the
physical growth of the city, agricultural land around the city has gone under
construction in the city.
