Columbia River ESI: SOCECON (Socioeconomic Resource Points and Lines)

This data set contains vector points and lines representing human-use resource data for Columbia River. In the data set, vector points represent aquaculture sites, boat ramps, coast guard stations, ferry sites, hatchery sites, locks and dams, marinas, recreational fishing sites, subsistence sites, and water intakes. Vector lines represent roads, bridges, and state borders. Location-specific type and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Columbia River. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the MGT (Management Area Polygons) data layer, part of the larger Columbia River ESI database, for additional human-use information.
