Abstract

National fundamental geo-entity construction has been vigorously promoted by the Ministry of Natural Resources of the People's Republic of China. As one of the core products, it is a digital abstract expression of the real world in the formof2 dimensions, which is difficult to fully meet the actual needs of analysis, calculation and use in the 3-dimensional digital space. This paper designs the process and key technologies for collecting elevation and height information of fundamental geo-entities to upgrade them from 2D to 3D form. This paper elaborates on the implementation process of key technologies such as elevation information acquisition based on DEM, stereo measurement of elevation information, height information acquisition. A practical and feasible process for elevation and height acquisition method of fundamental geo-entity has been formed, which effectively utilizes the advantages of geo-entities in information carrying, expression, sharing, and association. The experimental results show that the production process described in this paper can quickly and effectively obtain elevation and height information of geo-entities and result in 3Dfundamental geo-entities, providing technical support and important references for upgrading fundamental geo-entities from 2D to 3D form.
