Research on construction method of BR-TIN spatial data model based on object
Construction method of traditional three dimensional model generally applies only to the geographical entity of regular and simple shape,it is difficult to accurately describe and express the irregular geographic entity of morphological and comples structure and its inner logical relationship.This paper based on the analysis of the elements of spatial entities,to express three-dimensional space by the basic elements,organicly combine the Boundary Representation(BR)model and TIN,proposes the BR-TIN model.The paper describes geo-graphic entity spatial data model and its construction method based on the BR-TIN,discusses the analysis of spatial topological relation and 3D visualization based on BR-TIN model,and this model will be used to build a single building,to provide a new thought and method for constructing geographical entity spatial data model and analysising spatial topological relations in the network.
