Embodiment 1

[0100] In the 2016 and 2017 basic geographical monitoring projects in Shandong Province, according to this invention technology, some county-level task areas were selected for dynamic update, and the update efficiency was compared with 10 people participating. The results are shown in the table below.

[0101]

[0102] It can be seen from the above table that, using the technology of the present invention to update the county-level geographic provincial database, the data update efficiency of Dongchangfu District has been increased by 23%, and the data update efficiency of Ningjin County has been increased by 30%, and the update efficiency has been significantly improved. Especially in the stages of data distribution and data edge integration, the present invention has obvious technical advantages, which effectively shortens the time for data pre-preparation and post-arrangement, and effectively avoids the occurrence of errors.

Abstract

The invention discloses a multi-user operation dynamic updating method for geography province-circumstance monitoring. The method comprises the specific steps of user authority setting, data export, change finding, data quality testing, data preprocessing and updating warehousing. Change type classification is performed mainly for ground cover classification data and geography province-circumstance element data in a geography province-circumstance monitoring data library, special attribute fields are set for recording specific change shapes, and the method has the functions of being capable ofachieving multi-user simultaneous operation, incremental updating and automatic warehousing.

Description

technical field [0001] The invention relates to the technical field of geographical information, in particular to a multi-person interoperable dynamic update method for geographical situation monitoring. Background technique [0002] The geographic situation database includes surface coverage data, geographic situation element data, remote sensing image interpretation sample data and metadata, and has the characteristics of full-area coverage, seamless, high-precision, etc., and realizes the integrated management of geographic situation results data, 2D and 3D display, information query and analysis, achievement application service, database operation and maintenance, etc. [0003] The process of the traditional update method of the geographic provincial situation database is as follows: firstly, the data of the previous year is exported from the database in units of counties, and secondly, each operator manually cuts out the operation data according to the assigned operatio...
