Geographic data multi-database collaborative updating maintenance method and maintenance system

Abstract

The invention relates to the field of geographic information system application, in particular to a geographic data multi-database collaborative updating maintenance method and maintenance system. According to the geographic data multi-database collaborative updating and maintaining method, a terminal and a server side are included, a map updating preprocessing module is deployed on the terminal, and a plurality of databases and a synchronous service module are deployed on the server side, and the method comprises the steps that 1, the map updating preprocessing module on the terminal preprocesses geographic data, and the preprocessed geographic data obtains a unique identifier; the unique identifier is used for marking the synchronization relationship of the data; 2, a synchronization service module located at a server side sets synchronization marks for tables of different databases, and 3, the synchronization service module receives the geographic data from the map updating preprocessing module and distributes the geographic data according to the unique identification of the geographic data and the synchronization marks, and the databases update the geographic data.

Description

technical field [0001] The invention relates to the application field of geographic information systems, in particular to a multi-database collaborative update maintenance method and maintenance system for geographic data. Background technique [0002] At present, in municipal natural resource government departments, various basic geographic data, thematic spatial data, etc. are often produced and updated by various sub-departments, entered into their respective management databases, and then transferred to local natural resource authorities for storage and updating. The cycle is long, the process is many, and the current data is poor. The development of a corresponding spatial database collaborative update system will help the competent authorities to obtain the latest spatial data in a timely manner, strictly control data standards, and improve data quality at the same time. Based on this purpose, the present invention develops a corresponding spatial database collaborati...

Problems solved by technology

[0004] However, the above technical system has the following deficiencies: 1. The single database update mode system is closed, the data import and export operation is difficult, and the update cycle is long

2. In multi-database update, manual update requires high skills of operators, difficult operation, long update cycle, and data update errors caused by operation errors are prone to occur.
