The present paper focuses on determining the most important factors affecting urban growth in large cities of Iran through modeling and comparing the common and diverse points of urban growth obtained from other studies. For this purpose, by reviewing the theoretical concepts associated with urban growth, quantities and measurable variables are developed as proper frameworks to study the influe...

Reflectance characteristics of human settlements influence energy fluxes in the physical environment as well as our ability to monitor urban growth with satellite-based sensors. Spectral heterogeneity at the scales of 10 to 30 meters complicate the traditional land cover classifications derived from moderate resolution satellite imagery in urban and suburban areas. In this study we consider pop...

1. introduction urmia is one of the important historical cities of iran which in recent years has been associated with physical-spatial rapid expansion. one of the necessities of spatial planning of urmia is controlling the rapid expansion of the city in marginal areas that are unbalanced fertile land and industrial and mineral soils are under construction and this problem has presented numerou...

What is called the problems of Tehran metropolis now a days, is deep- rooted in the policies ofurban planning in our country. Since not far past up to now, immigration from all over the country to Tehran, irregular growth of urban population, inconsistency with urban infrastructure development, environmental pollution and low quality of living areas, erosion of self -growing fabric in most area...

the complexity of urban systems in our recent world, make it difficult to evaluation and explanation of their changes with traditional and customarily methods. in the past, remote sensing has shown an ability to detect and describe urban growth patterns at different spatial scales. with new remote sensing devices (e.g. ikonos), with innovative image processing techniques and with further develo...

Urban sprawl, or the unplanned and uncontrolled spreading out of built-up areas in Zaria urban area causes problems of congestion, poor urban basic infrastructure delivery and poor urban planning. This paper analyzed the pattern and implications of urban sprawl using GIS and Remote sensing as an improved approach to analyze and explain sprawling beyond the traditional spatial or cartographic ma...

African cities face immense challenges over the coming decades. As countries urbanize, African cities must maintain service provision for rapidly increasing populations, yet with limited resources. In particular, urban food systems must be able to cope with regional food shortages and catalyze (or at least enable) the distribution of food from diverse sources in order to ensure that the cost of...
