| Abstract: | Rapid data update at the provincial level for geographic information public service platform is a problem in surveying and mapping production units. In this experiment,we use the up-to-date rural cadastral survey results with high precision to conduct the DLG update for the platform,and classify and extract the rural cadastral elements and extraction. Based on the comprehensive automatic update technical model,we complete data joint and integration of urban and rural areas during this period. Rapid update is realized for residential elements in the administrative division unit 1∶10 000 DLG. This study provides reference for rapid data update of the provincial geographic information public service platform. |
