Towards an Iranian Geospatial Data Transfer Standard

Geospatial data sharing is of vital importance for merging different agencies and organizations as it decreases duplications and reproductions of the data. One of the most important obstacles in this context is the absence of an efficient spatial data transfer standard. The purpose of this paper is to describe the steps involved in designing and developing a spatial transfer standard for Iran. Designing levels of geospatial transfer standard and its specifications are introduced. Existing geospatial transfer standards are scientifically analyzed. The analysis phase helps the project team to increase the speed of designing phase and decrease the associated risks. On the other hand a selected or developed geospatial transfer standard for Iran should comply with its existence data and data formats, so studying and assessment about them seem an important level in this case. The project is on going, and the paper discusses the current results of the research.
