Development of a WebGIS-based digital database for agricultural production land in Phu Yen province

Abstract

This study presents the development of a WebGIS-based digital database for the management and utilisation of agricultural production land in Phu Yen province (before the administrative merge), based on the integration and standardisation of spatial and non-spatial data. The main data groups include current landuse status, soil and agrochemical properties, land mapping units, and detailed land suitability classifications, proposals for crop restructuring, and fertiliser use guidelines. The database was developed using the national VN-2000 coordinate system, managed on the open-source QGIS/PostGIS platform, and deployed as an online WebGIS. This sophisticated system allows users to browse, search, query, and utilise agricultural land information down to the commune level, supporting production direction, territorial planning, and agricultural land-use management. The research results contribute to improving the efficiency of land resource management while promoting digital transformation in the local agricultural sector.
