The MarineCadastre.gov Map Gallery, a collection of ArcGIS.com maps, enables ocean planners to create custom data viewers by combining authoritative data from the MarineCadastre.gov Data Registry with more locally relevant web map services. Some examples of custom data viewers are below. Users can import data into an existing map within the gallery or start fresh. View the Map Gallery resources to learn how to create a map for the Map Gallery. Additional maps can be found within our group on ArcGIS.com.
