Discussion on the Integrated Database Construction of Historical and Current Land Survey Data:Taking Dongguan as an Example
Through the construction of historical and current national land survey databases, the problems of scattered storage and diffi-cult application of national land survey data from different years have been solved. A national land survey database with multi-period, fully aggregated, comprehensive coverage, and unified updates has been established. Finally, the land use database and data resource management system covering three periods are realized. The construction of the integrated database for historical and current data of land survey has effectively improved the utilization and historical value of land survey data results, providing important data support for the coordination of natural resource business and the management work of relevant departments in the city.
