Digital Coast Act This bill provides statutory authority for and revises the National Oceanic and Atmospheric Administration's (NOAA's) Digital Coast program. (The program currently exists under NOAA to provide data, tools, and training that communities use to manage their coastal resources.) NOAA must focus on filling data needs and gaps for critical coastal management issues and support continued improvement in existing efforts to coordinate the acquisition and integration of key data sets needed for coastal management. NOAA may enter into financial agreements and collect fees to carry out the program. Additionally, NOAA may establish publicly available tools that track ocean and Great Lakes economy data for each coastal state.
