RESEARCH AND REALIZATION OF CITY VIRTUAL GEOGRAPHIC ENVIRONMENTS
摘要
Abstract
Virtual geographic environments is a new geographic language;city virtual geographic environments is the application of virtual geographic environments in the city. Using remote sensing image as the data resource,the city virtual geographic environment is generated by integrating the TIN model and CSG model. In it the TIN model builds the topography and the CSG model builds the constructions. The ground contours of constructions are extracted as the limit constraints of TIN model, through this the 3D landscape of city virtual geographic environments is set up,and the share of 3D space information of city is realised.关键词
