A method and device for linked updating of basic geographic information

Abstract

The invention discloses a basic geographic information linkage updating method and device. According to the method, basic geographic information original data collected by geographic information departments of all levels are fused, the processing flow of all data in linkage updating is standardized, a scientific and practical linkage updating guarantee mechanism is established, and updating is achieved when changes exist. By adjusting the basic geographic information original data collected by the geographic information departments at all levels, the data in the database conforms to a unified standard, all historical data are reserved, data updating is more accurate, and possible change trends can be obtained from the data to judge the original data collected each time. According to the method, the production and professional service directions can be driven and updated by the basic geographic information change discovery result by taking the current situation priority of the basic geographic information as a guide.

Description

technical field [0001] The invention relates to the field of geographic information data processing, in particular to a method and device for linked update of basic geographic information. Background technique [0002] The update of basic geographic information is the basic and strategic work of national construction and economic development. As the demand for basic geographic information data from all walks of life is getting higher and higher, how to realize the division of labor and coordination of geographic information departments at all levels, the integration of surveying and mapping technology, and the linkage update mechanism of basic geographic information for information sharing and collaboration between surveying and mapping systems and professional departments has become an urgent need. solved problem. [0003] The current update of basic geographic information mainly adopts the periodic data update method. Although some results have been achieved, under the ex...

Problems solved by technology

[0003] The current update of basic geographic information mainly adopts the periodic data update method. Although some results have been achieved, under the current update method, the production cycle of basic geographic information is long, and the current situation is not strong. The goal of timely update on demand is still far away There is a big gap

[0004] In addition, due to the scattered basic geographic information resources of geographic information management departments at all levels, the sharing and integration of basic geographic information among various departments is not high, and duplication of construction affects update efficiency

Due to the existence of various standards in the collection process of the existing basic geographic information, updating it requires a lot of conversion work.
