Design and practice of online collaborative updates for cloud database of map world
Based on the efficient update and release requirements of online public services of geographic information,this paper designed a cloud database solution for online collaborative updates of provincial maps.In the national and provincial unified public cloud environment,the solution designed and deployed the provincial cloud database based on PostGIS and developed the entry data quality inspection tool and cloud database management system supporting unified quality standards and customized expansion.Through the combination and construction of update mechanisms and collaborative models,such as the change discovery of geographic information elements,offline linkage update of provinces and counties,and online synchronous updates of provinces and cities,the collaborative data update models of synchronization of countries and provinces,as well as the collaboration of provinces and cities were realized.The pilot practice in two municipal nodes of Huangshan City and Chuzhou City and two county nodes of Shexian County and Mingguang City under the administration shows that the solution can realize the dynamic update of online data services,meet the needs of timely release of geographic information public services,and provide a useful reference for the construction of a new generation of geographic information public service platform.
