Abstract

Abstract:

There is difference and relativity between the updating mode of map and DLG. Based on the research of DLG incremental update and integrated management of map and DLG, a graph-database integration updating method for geographic is proposed. The spatial information of geometry and attribute and the symbolic graphic information are organized in the unit of geographic entity. With map presentation of DLG incremental information, the incremental information of symbolic graphic information is obtained. Real-life data were used to verify the effectiveness and the advantages of easy realization by computer, high efficiency and scalability, and being suitable for the integrated updating of maps and DLG.

Key words: graph-database integration, incremental update, geographic information update, map update
