Application of GIS to update, operate, and exploit geographic database in Dong Ha City, Quang Tri province

Abstract

We used the Production Mapping tool in ArcGIS software to update, operate, and exploit the 1/10,000-scale geographic database in Dong Ha City. We updated the geographic database of Dong Ha City from satellite images, including seven groups of updated data: Border and boundary data, Measurement data, Residential data, Topographic data, Traffic data, Surface overlay data, and Hydrological data. In addition, we conducted the operation of this geographic database with a centralized model and a decentralized model; simultaneously, we exploited the database under three objects: Users, Communication Channels, and Application Platforms. Applying the results to work practice might create a platform for other databases not only in the natural resources and environment but also in other fields, such as transportation, construction, and agriculture.
