Monitoring the dynamics of urbanization in contemporary Iran using multi-temporal images DMSP / OLS

Monitoring how large-scale expansion of urban areas is very important for planning urban development and the prevention of catastrophic problems in metropolitan areas. However, in most cases, lack of basic information in this area, especially in developing countries is a major obstacle to achieve this. So in order to check the balance was used in the Iranian city of urban primacy index and Rank-Size cities from 1335 to 1390. Using data from urban population census was used in different periods. As well as for monitoring the dynamics of urbanization in contemporary Iran through the eyes of space-time benefit from multi-temporal images DMSP / OLS for the years 1371 to 1391. The results showed that there is a phenomenon of urban primacy with regard to all aspects of the urban system, in all these periods; And overall results of the logarithmic distribution Rank-size cities in the period 1335 to 1390 shows, That in 55 years time, the distribution of the cities to the imbalance in 1385 showed that desire and imbalanced distribution with an absolute slope of 1.142. Finally, in order to analyze images of DMSP in relation to urban areas and the GDP of the linear regression model was used, The results showed that there is a linear relationship between light at night and population, urban population and GDP. R2 is the urban population equal to 0.854. Which shows the images can be used as an agent to identify the dynamics of the urban system. Which shows the images can be used as an agent to identify the dynamics of the urban system.
