MODEL OF GEOGRAPHIC INFORMATION SYSTEM IN SUPPORTING FLOOD RISK REDUCTION A CASE STUDY OF CHOENGSAE SUBDISTRICT, SONGKHLA PROVINCE

Abstract

This Participatory Action Research (PAR) aims to study and develop a Geographic Information System via the internet, which is a flood database in Chongsae Sub-district, Songkhla Province, to have the capacity to display spatial data to support flooding information with a description of the boundary, scale and can be inquired for detailed information from a database over the internet in of village number 3 and 4 Chongsae village, Chongsae Sub-district, Krasaesin District, Songkhla Province, which is two affected villages in this area by field data collection and developing through Quantum GIS, GeoServer and OpenLayers software together with PostgreSQL database. Target groups are leaders, core-team members, Chongsae Municipality officers, and those involved in flood management, Village No. 3, Village No. 4, Ban Choeng Sae. The results are found that the Geographic Information System model for spatial analysis consists of 4 crucial elements of the database, namely physical and basic infrastructures aspects, such as water sources, forest areas, topography, administrative district boundaries, community traffic routes, ditches/drains, house structures, and restrooms; economic aspects, such as income, occupations, tools of the trade; social and livelihood aspects, such as places/ organizations in the community, institutional information and community networks; and flooding aspects and local management in the past, such as past five-year flood database (2014-2018), risk points, vulnerable groups, and management. In addition, satisfactory assessment of system operation and map display are found to be in good condition, which in the future a researcher will focus on studying analysis of more relevant inundation supportive information, such as safe routes, evacuation points for further information of the community.
