Abstract
The planning database is a big data system, especially the provincial planning data. The planning information also needs to be disclosed to people in smart cities. Putting planning data on the web is necessary, but the speed of information extraction is still limited. The paper presents the improvements in the performance of GIS using PostgreSQL and WebGIS. The planning database of Nghe An province (Vietnam) which is a large province of Vietnam is collected and evaluated. Compared to traditional Arcgis, the proposed system allows improving the execution by two times. Moreover, WebGIS supports users to explore the system faster and more easily.
