) Abstract: With the promulgation and implementation of a series of related standards on mapping, such as 《Basic Provisions Of Standardized Data On Fundamental Geographic Information》, it greatly accelerates the process of standardization for topographic maps and the quality is also rising
DLG data tends to coincide on schema and attribute structure
The standardization of DLG data reduces the inconsistency and uncertainty of the previous DLG data and greatly enhances the feasibility of automatic three-dimensional visualization for vector-based map
In this paper, the course of 3d visualization of vector map based on standardized DLG is studied from the aspects of standardization of data processing, vector data modeling and the display of three-dimensional terrain
