National Geographical Organization Scientific- Research Quarterly of Geographical Data (SEPEHR) 2588-3860 21 83 2012 10 22 Application of Geographic Information System (GIS) in Urban Planning Application of Geographic Information System (GIS) in Urban Planning 51 57 26236 FA Taher Parizadi GIS Instructor, International University of Qazvin Sorayya Rowshangar Master's Student of Geography and Urban Planning, University of Payam-e-nour Journal Article 2012 03 30 Geographic Information System (GIS) is a platform for saving, storing, managing and analyzing geographic information. It is designed to simultaneously work with geographic and descriptive data. Nowadays, possessing timely data and exploiting necessary information are especially important. In this regard, Geographic Information System, as an important tool in managing ground related data, provide the possibility of exploiting necessary information and finding complex and hidden relationships among different phenomena. The present article investigates different applications of Geographic Information System in urban planning and urban development plans. To reach this aim, we first investigate background, evolution process, the systems’ principles and capabilities in the framework of software collections and then propose the procedure used in preparing two samples of urban development plan and explain the role of each GIS applications in the production of this plan and its function. Results indicate that with growing development of modern technologies, the application of geographic information system in urban planning has increased and satisfy urban development plan in the context of qualitative, quantitative and digital analysis. Then, some problems facing GIS application in the system of macro planning and urban planning in Iran are mentioned.   Geographic Information System (GIS) is a platform for saving, storing, managing and analyzing geographic information.
