The Research on Implementation Methods of 3D GIS

Article Preview

Abstract:

3D GIS is an intuitive and effective method of realistic geo-information. Its spatial analysis function meets the user’s needs of inquiring and analyzing to the geo-information. 3D GIS has been widely used in geoscience and urban planning. This article introduces the 3D GIS firstly. Then it discusses the implementation methods of 3D GIS in detail. These include underlying development, secondary development and implementation by remote sensing images. At last, their merits and faults are analyzed, and the paper gives the suitable conditions for different applications.
