Spatial Data Infrastructure (SDI) is one of the development tools in all political, social and economic aspects and its purpose is spatial data coordinating, facilitating management, and geospatial data sharing in a participating environment. As producing spatial data demand is increasing by time, and chairmen and high managers’ information about using spatial data for proper decision making is promoting, a serious need to establish national SDI is felt. Therefore, national SDI establishment provides a proper foundation for sustainable development of countries. Thus, we have surveyed the national SDIs (NSDI) situation and their components in 10 selected Asian countries and we‘ve compared them in order to find out implementation challenges and obstacles and to predict future issues and problems to represent successful NSDI implementation solutions. In this paper, the evaluation of the NSDI situation of these countries specified that Iran is in her elementary phases of NSDI implementation and have compiled its strategy plan by this time. Thus the recommended solutions in the result of this article would help to accomplish this national project effectively.
