The Graphic Techniques in the Urban PlanningFrom Basic Tool to Prominent Technique

The increasing development of urban community under the influence of irregulargrowth population and immigrations, leading to unplanned constructions and itsuncontrolled expansion brought about many changes in the spatial structures of urban,This overall changes in its turn require more than ever informed direction, substantialorganization and suitable spatial design. On the other hand, the fundament social,cultural and economical changes are seeking an extensive transformation in the spatialstructure of environmental complexes. Certainly, such changes can not advancewithout effective planning and guidance of urban developers.Urban and regional planners advocating formulating and regulating plans andadopting policies need continuous acquisition of information. Urban planning anddesigning from perception to designing and implementing urban plans need correct,precise , rapid and up-to-date information of local, urban and region.So far, cartographical elements (such as graph, histogram, map, photo, aerialphoto, satellite image and geographical information system) acted as a basic tool forsecuring correct, precise and up to date information leading to better understanding ofurban and regional potentialities, trends of urban planning and designing and finallyproviding an accepted image for urban .Over the recent years, cartographic knowledge, which is influenced byelectronic, satellite and automation has been on the threshold of a fundamental changeand in addition to its determining role of simulation, it has transformed into a uniquetechnique in modeling (designing for future) for the purpose of designing and planningand testing of processes and analyzing the results prior to the implementation.The aim of this article is conducting a research to explain the influence ofautomation in changing the cartography and transforming it into an effective andsalient technique in urban and regional planning and presenting a suitable model.
