Combining with the development of augmented reality (AR) technology,this paper proposed a conceptual framework about augmented geographic environment (AGE) based on the development of virtual geographic environments (VGE).Key computing and visualization technologies of the fusion of virtual geographic process and 3D printing realistic model,including the coordinate matching technology of virtual geospatial space and real geographical space and the technology of occlusion processing,are
