Abstract
Sustainable development (SD) has been introduced as the first priority of societies. Also, information and communication technology (ICT) has played an important role in this process. It has been shown that existing social, economical and political developments are important factors in ICT’s benefits diffusion and effectiveness. The developed societies could gain ICT immensely using their powerful development infrastructures while in developing societies, similar activities have been failed due to lack of such an infrastructure. It is recommended that all activities undertaken towards SD, dealing with common infrastructures could support SD and ICT, to overcome this imparity and reducing the gap between developed and developing societies. In this research, spatial data infrastructures (SDI) are introduced as one of these infrastructures, which could be developed comprehensively in different societies. Then the national spatial data infrastructure (NSDI) development is studied and ICT and national ICT strategy evolutions are traced, analyzing defined modern SDI and ICT infrastructure concepts.
