Based on research and practice, this study has applied information technology to support the development of databases of planning and land-use plans, helping the State Management Agency of Land catch the information quickly, as well as complete the information system of planning and land-use plans for the construction of land databases in Quang Binh district, Ha Giang province. While conducting research, the authors used primary and secondary investigation, legacy method, method of information technology software application, and modeling method for building the database. Initially, the authors constructed a database of district planning and land-use plans. The study shows that the data and documents collected in Quang Binh district meet the requirements for building databases of planning and land-use plans. However, the collected data still needs to be standardized according to the provisions of Circular No. 75/2015/TT-BTNMT by using MicroStation V8i software and VBDLIS QUYHOACHKHSDĐ software to build and complete a database of planning and land-use plans [2]. The authors compared the software’s advantages and disadvantages to find solutions during practical application to improve the efficiency of Quang Binh district planning and land-use information data management and exploitation.
