The Thai government is preparing to develop a nationwide “One Map of Water” to create a shared database for monitoring floods and other water-related threats, with the aim of improving disaster response and coordination.
The proposed system is intended to bring water-related information from different government agencies together on a single platform. This would allow authorities to access more consistent and up-to-date information when monitoring developing situations.
Thailand has several agencies responsible for water management, disaster prevention and emergency response. Sharing information through a common mapping system could help reduce gaps between agencies and provide a clearer picture of conditions in affected areas.
The map is expected to incorporate information relevant to flood monitoring, including water levels, rainfall, waterways and other factors that can influence the movement and accumulation of water.
A centralised database could also help authorities identify vulnerable areas more quickly and support decisions on evacuations, water management and the deployment of emergency resources.
The initiative comes as Thailand continues to face increasingly complex weather conditions, with heavy rainfall and flooding posing recurring risks to communities, agriculture and infrastructure.
Officials have stressed the importance of improving coordination before and during disasters. A shared information system could allow agencies at the national and local levels to work from the same data when responding to emergencies.
The One Map of Water is also expected to support longer-term water management by giving authorities a more comprehensive view of the country’s water resources and risks.
The project reflects a broader effort to use digital technology and data integration to strengthen Thailand’s disaster preparedness and improve the speed of government responses when water-related emergencies occur.
Further details on the system, including its full scope and implementation timeline, are expected as relevant agencies develop the plan.
