Influential Factors on Preparation of Large Scale GI (Ground Information) Map Using Photogrammetry

The rapid growth of the world's population and the expansion and development of cities, urban suburbs and rural areas, and the steady and unrelenting increase of human activities on the earth, all indicate the necessity of more detailed, diverse and up-to-date ground information (GI) in all spatial and temporal aspects. This reinforces the role of photogrammetry, in particular its refining capacities for production of ground information (GI) from high-resolution aerial or satellite imagery. In this paper, the author has focused on factors that affect the efficiency of this process.
