Application of WEB GIS to track water situations

Abstract

Currently, Thailand has implemented a wide range of systems for the analysis, monitoring, and forecasting of natural disasters to support water resource management. Recognizing the importance of integrating these diverse data sources, the Hydro–Informatic Institute (Public Organization) (HII) has developed a web-based Geographic Information System (WEB GIS) that consolidates information from various systems established by the institute since 2012. These systems include the Flash Flood Warning System, Flood Forecasting System, Drought Monitoring System, Simulating Waves Nearshore (SWAN) System, among many others.This web application operates through an online platform that efficiently integrates and overlays data from each system. It presents information in digital formats such as maps and charts, and also allows data export in formats like Shapefile (.shp) and Comma-Separated Values (.csv) for further risk assessment, situation analysis, and precise monitoring. In addition, the system provides comprehensive situation reports and potential impact assessments across multiple dimensions and supports data sharing through an Application Programming Interface (API).Thus, the WEB GIS serves as a vital tool for government agencies and other relevant organizations in the management of water resources, significantly contributing to the reduction of risks associated with natural disasters in Thailand.
