Our project involves 70 teams in 27 countries photographing and documenting freshwater and marine sites. Images and data are shared through an interface constructed with ArcGIS JavaScript API. It allows users to see where we’re working and drill into any project, site, and station to see their data and how conditions are changing. We plan to construct photomosaics and use ArcGIS to provide spatial analyses and a critical link to the entities working to understand and manage aquatic environments.
