An Open Data Cube Platform as a Coastal Digital Twin: Prototypes to Inform Flooding and Environmental Health

Earth Science Digital Twins are rapidly evolving to advance earth science understanding and societally relevant decision making. Coastal hazards pose complex and compound threats to dynamic human settlements and land use, inviting their analysis using digital twin technologies. A geospatial approach requires a framework for data assimilation that spans Earth observations, in situ sensor networks, environmental models, and characterization of human population and infrastructure assets. In our study, an Open Data Cube is developed as the core integration platform for a series of prototype case studies: 1) coastal mosquito-borne disease exposure assessment; 2) dasymetric mapping of vulnerable populations; and 3) integrated modeling and observational assessment of a King Tide flood event for Hampton Roads, Virginia (USA.) These prototypes are described with preliminary results. The paper also discusses benefits of the ODC as a Digital Twin as well as impediments and future developments for enhanced capabilities.
