Edge connection process for two-dimensional geographic entity data in new fundamental surveying and mapping
Due to the large volume,unique data structure,and complex semantic relationships of geographic entity data, traditional methods of data edge connection are not suitable for the production process of geographic entity data. This paper introduced the production database of geographic entities. With the help of production software,a reasonable data edge connection process was designed. The data edge connection process included edge data submission,boundary determination, data labeling,data downloading,edge production,and data uploading and updating. This process improved the efficiency and quality of edge connection and ensured the data integrity. The engineering examples prove that the edge connection process designed in this paper is reasonable,effective,and highly efficient,which effectively supports the construction of the new national fundamental surveying and mapping pilot project in Beijing.
