数字摄影测量技术与数字地球空间数据框架的建设

数字地球的构建与数字摄影测量、遥感、全球定位系统、地理信息系统、计算机、宽带网络、多维虚拟现实等新技术有着紧密的联系,数字摄影测量已成为构建数字地球提供空间数据框架的一种不可或缺的技术手段。基于数字地球的发展需求,结合数字摄影测量技术优势和最新发展,着重阐述了数字摄影测量在数字地球空间框架的建设中的作用。随着数字地球发展的深化,数字摄影测量将显示着愈来愈重要的作用。

The Digital photogrammetry and Construction of the Digital Earth

With the rapid development of new sciences and technologies, especially computer technology, space technology and information technology, the mankind has entered into the information era. There is no doubt that aerial photogrammetry especially digital photometry are getting more popular than before. As a subject of surveying mapping, it has developed into a new information industry from the traditional photogrammetry, and according to the photogrammetry itself,it has developed into photogrammetry and computer vision. At the same time, photogrammetry, GPS, computer internet and virtual reality are closely related to the establishment of Digital Earth. Digital photogrammetry has been proved to be one of the most important technology for providing Digital GeoSpatial Data framework in construction of Digital Earth. Based on the development of the Digital Earth, especially, the function and status of digital photogrammetry in construction of the Digital GeoSpatial Data framework are described form the point of the advantage technique of digital photogrammetry. With the development of Digital Earth, the digital photogrammetry will play increasingly important role.
