Implementation of NSDI has been considered in the 4th National Development Plan of Iran. Considering the fact that data are produced during daily activities of organizations, in Iran’s NSDI Strategic Plan, national organizations/ministries has been considered as the main custodians of NSDI’s data. However, initial studies show that these organizations are not still well-prepared for such participation. There are different problems with spatial data management within different departments of national organizations that make them not to be able to have a supportive collaboration in NSDI. Consequently, the development of Organizational SDI (OSDI) to make a specific organization to be prepared for cooperating in NSDI seems to be necessary.
In K.N.Toosi University of Technology, development of OSDI and the related challenges is under investigation (Mansourian and Valadan, 2006). As a part of the mentioned project, design and development of an OSDI for Iranian Ministry of Energy (MOE) is ongoing. Initial studies in the context of OSDI of MOE show that Distributed GIS should be used as a proper technology foundation for optimum spatial data production, updating, sharing, usage, and management within this organization (Mansourian et al., 2006). Distributed GIS is a distributed framework of accessing and processing geospatial data using geospatial information services over the internet or a Wide Area Network (WAN).
In this paper, the results of the research about MOE’s Organizational SDI will be described briefly. Then, various Distributed GIS architectures as well as OGC standards and specifications will be reviewed. Based on this study and MOE requirements (which have been highlighted in the OSDI studies), a proper structure for MOE’s Distributed GIS will be offered.
