55607 NAV_MARINE_LINE Entity Published / External 55600 South Carolina 2015 ESI NAVIGATION_MARINE Polygons, Points, Lines Data Set Completed The NAV_MARINE_LINE table contains the primary key - HUNUM - for the vector lines depicting locations of shipping lanes in South Carolina. The HUNUM links to all attribute information stored in the SOURCES and SOCECON tables, described below. See the Browse_Graphic section for a link to the entity-relationship diagram, which describes the relationships between attribute tables in the ESI data structure. The ESI data are intended to provide baseline environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources. The ESI data may be appropriate for many other coastal management efforts, though the original intent should be kept in mind.
