چکیده
Recent researches on Three-dimensional Geographic Information System (3D GIS) modeling technology were reviewed. The concept of 3D GIS modeling and its application in various fields were introduced. Essential techniques to realize 3D visualization were studied. A typical 3D GIS modeling usually contains the description and the transmission of GIS spatial data structure. GIS spatial data models were described and species of 3D GIS models were summarized. Current algorithms for transmitting data to 3D models were compared and analyzed.

Development of SISGeM - An Online System for 3D Geologic Modeling -
GIS can be readily used to manage and analyze 2D information and also afford 3D visualization of surface features. However, general-purpose GIS packages do not offer capabilities for constructing or visualizing 3D geologic models. GIS tools must, therefore, be appropriately tailored to handle geologic data and accommodate the special spatial analysis needs of geologic information. Since 3D geol...
