ItemFacilitating urban management through local SDI case study: the Municipality of TehranOLFAT, HAMED ; RAJABIFARD, ABBAS ; Qureshi, Faisal Masood ; Daneshpour, Seyyed Abdolhadi ( 2009)Integrated and sustainable management of cities is one of the most important challenges facing many countries. In this critical societal challenge context, spatial data is key for decision making, planning and management of cities. Thus, in order to have sustainable management and planning there is a need for managers and planners to have access to reliable, seamless and accurate spatial data. However, the current situation regarding availability, integration, sharing and its effective application by planners and decision makers is not very promising in many jurisdictions worldwide including Iran and Pakistan- the two countries under study by authors. Based on current situation, in urban management in Iran there is a need for an agreed platform that facilitates access to and sharing of spatially related data, services and other resources among different disciplines within any jurisdiction. This platform should also address characteristics such as standards and specifications for data collection, management, maintenance and distribution of spatial data. Having said that, in order to facilitate this situation and respond to the needs, many countries are developing Spatial Data Infrastructures (SDIs) which is a concept for facilitating and coordinating of sharing and integrating of data through different political and administrative levels. SDI can be developed at different levels ranging from local to state/provincial, national, regional and global. SDI as a platform can help to reduce the duplication and save resources in data collection which usually occur due to unknown information about availability of datasets among different urban organizations. In addition, organizations involve in urban planning can have access to a comprehensive dataset of the interested area like a city to achieve sustainable urban planning. This paper discusses the importance and benefits of developing SDI as an enabling platform for urban planning and management based on a case study, namely Tehran Municipality in Iran by exploring challenges and issues in accessing and sharing spatial data in this jurisdiction. The paper then presents and discusses the process and experiences of developing an SDI Roadmap for this municipality.
