Development of 3D GIS modeling technology

Abstract

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. © 2008 International Federation for Information Processing.
