Analysis of Street Landscape Structure

“A city can be read through its streets”. Stéphane Douady، Professor of Dynamics of Out-of-Equilibrium Systems in Paris Diderot University began his speech with these words. He continued by explaining the significance of the street structure: “When we think of a city، we first think of the houses. While they can be replaced when destroyed or abandoned، the streets remain stable”. Dr. Douady’s multidisciplinary team، consisting of physicists، architect، landscape architect، sociologist، urban planner and geographer aim design a plug-in called (Morpheo) for GIS Software in order to define indicators for the reading of city as a complex phenomenon. Adding this plug-in can can result in understanding city changes and meaning. The main idea of this plug-in is to use topological indices (indices that do not change with changing geometry، other than cutting off) in order to analyze Simplified map on the basis of streets. Stephen Douady in the workshop of “process of urban landscape” relying on his visit to Tehran neighborhoods، raised questions about the evaluation of structured indices. He tried to test the accuracy of Morpheo plug-in by verifying the results of Tehran map analysis and his field observations. He explained the reasons for structures by showing different images of the street and asking about their structure and their adaptation with the analyzed plan.
