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 contents, national fundamental geo-entity relationship faces new requirements of richer content, more intelligent construction, more flexible association, more intuitive expression, and more efficient application. This paper analyzes the existing entity relationship types, defines the content of national fundamental geo-entity relationship, compiles the geo-entity relationship construction table, establishes a practical and feasible process for geo-entity relationship construction through engineering practices. The first batch of national fundamental geo-entity relationship products show that the production process described in this paper can quickly and effectively achieve the construction of national fundamental geo-entity relationship that are rich in content and convenient to apply. It has certain reference and promotion practical in the construction and integration of multi-scale geo-entity relationship at the national, provincial and municipal levels.
