Resumen
Spatial Data Infrastructure (SDI) is a long term, evolving process without a priori known results. Different countries try to develop a National SDI (NSDI) not always with a successful outcome. Although the successes are presented thoroughly (e.g. SDI best practice), it is equally important to highlight unsuccessful efforts in order to comprehensively examine different aspects of the SDI development and to acquire a more holistic approach and integrated perspective on the subject. The first Greek NSDI effort that is presented in this paper is an example of an unfruitful first attempt. Examination and assessment of this effort, lead to interesting and hopefully constructive conclusions towards a broader understanding of the SDI development. In order this first effort to be assessed, three time periods in the Greek spatial evolution are determined. These periods seem to have affected each other. People, concepts and inadequacies of a period appeared also during the next one, forming a kind of pattern. The discussion of aspects that influenced and characterized this effort reveal the multiple difficulties and problems the Greek NSDI development had to face.
