【Abstract】 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.更多还原
