It’s important to note that the Information collection by itself cannot define and sufficiently provide all the necessary actions to be taken in order to get them accessible and useful for users. The data management and establishment of a proper and reliable DBMS and finally a GIS system at the same time are vital crucial in the course of 3D application that will be discussed throughout the paper. The existing drawbacks and elements needed to be considered for the cartographic presentation are the key issues in three-dimensional world visualization. The elaboration on the 3D information and its knowledge transfer to the users in a SDI framework as well as the requirement recognition of beneficiary organizations will be the next step in this paper and the most probable problems will be studied in this stage. At the final stage, we’ll come up with conclusion, warnings and recommendation.展开更多

In the following, due to the essential role that GIScience can play on the success trend of Sustainable Development, GIScience will be defined and its importance will be discussed as an effective tool in its logical procedure of Sustainable Development. The decision making support systems—using Geo-information and spatial data—is merging increasingly into other disciplines design and techniques day by day. So It would be worth investigation on the technical aspects of sustainable development and its consideration in projects development in general, throughout the literature review and SD requirements. The successful sustained achievement will depend on clear “political” answerability for its reliability and local regulatory environment. It should be in harmony with the additional superior prescription and ruling at the national or international levels by the use and utilization of national spatial data infrastructure. The paper will ends up with a set of suggested practices in the development of Spatial Data Infrastructure (SDI).展开更多
