This document summarizes big data applications in environmental monitoring and management in Korea. It defines big data and describes how Korea produces terabytes of environmental data each year from monitoring water quality, air quality, hydrology, meteorology and other areas. The document suggests that integrating various environmental data sources and linking them with social data can generate new insights. It provides examples of how analyzing large volumes of water supply data helped optimize water pressure management and reduce energy consumption. Finally, the document calls for developing open data platforms to accelerate big data utilization and contribute to addressing environmental and social challenges through public-private-academic collaboration.

8. When various environmental data are analyzed and interlinked, they can have the potential to
create new knowledge and intelligent solution for environmental challenges and societal challenges
(Water·Air quality, energy, noise, transport, biodiversity, climate, meteorology, deforestation)
analyzing and interlinking Environment information

9. Integrating Environmental data with social data
To nowcast and forecast trends such as flu outbreaks, industry flows, political opinions and etc.
→ faster, more accurate, more globalized and localized.
