Popis

This data set contains the following human-use resource data for Northern California: access areas, airports, aquaculture sites, beaches, boat ramps, Coast Guard areas, commercial/recreational fishing areas, essential habitats, historical sites, hoists, marinas, staging areas, subsistence areas, wash overs, and water intakes. Vector points and lines in this data set represent the human-use locations. Location-specific type and source information is 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 Northern California. 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 Northern California ESI database, for additional human-use information.
