Abstract

This paper presents a hybrid model for three_dimensional Geographical Information Systems which is an integration of surface_ and volume_based models.The Triangulated Irregular Network (TIN) and octree models are integrated in this hybrid model.The TIN model works as a surface_based model which mainly serves for surface presentation and visualization.On the other hand,the octree encoding supports volumetric analysis.The designed data structure brings a major advantage in the three_dimensional selective retrieval.This technique increases the efficiency of three_dimensional data operation.
