A perspective of geographic information system in OEOC surveying department:

Required procedures were done during past year for establishment of integrated web database in Tehran office. Beneficial measures were done in this case after fulfillment of feasibility studies and consideration of company’s objectives.

Auto pilot representation of Bahar 2D project was completely different from what was previously occurred; and usage of elevation model and satellite images which were provided to create a realistic and 3D view of district along with representation of all details and also with high capabilities in sampling question and answer process is one of the GIS projects.
