Spatial Data Infrastructure (SDI) is known as a fundamental comprehensive approach of spatial data managing and sharing. Due to the complexity of establishing SDI, creating SDI has been considered as serious challenge, especially in developing countries. Successful and sustainable SDI can be developed when social, organizational and cultural issues are resolved in harmony with the technological ones. The framework of the present research is constructed on the basis of a survey and an SDI readiness model. Following a review of the research background, and taking into account the interaction of relevant indicators, criteria for establishing SDI were identified. After identification of the criteria, the data were collected through questionnaires and interviews with experts. 185 questionnaires were completed by 75 government-based departments, organizations, universities, and the private sector in East Azerbaijan province. The results were analysed and a readiness index was computed. The minimum chance of successfully establishing SDI was determined as being about 64.12%, while the maximum rate was 89.48%. The results are of great importance for analyzing the factors which may have significant impact on successful SDI development in East Azerbaijan province.
