This data set contains vector polygons depicting locations for navigation/marine areas for Massachusetts and Rhode Island. Navigation/marine areas include anchorage areas and shipping lanes. The polygons in the NAV_MARINE data layer may overlap where an area is associated with more than one agency or feature type. As an example, multiple parks may fall within a county boundary, which may itself fall within a larger polygon depicting the jurisdiction of an Army Corps of Engineers region. Location-specific type and source information are stored in associated data tables (described below) designed to be used in conjunction with this spatial data layer. This data set is a portion of the ESI data for Massachusetts and Rhode Island. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the NAV_MARINE_LINE (Navigation/Marine Lines) and NAV_MARINE_POINT (Navigation/Marine Points) data layers for additional human-use information.
