The vector data file is included in "Habitat_OffshoreGaviota.zip," which is accessible from https://doi.org/10.5066/F7TH8JWJ. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Cochrane, G.R., Hartwell, S.R., Golden, N.E., Kvitek, R.G., and Davenport, C.W. (S.Y. Johnson and S.A. Cochran, eds.), 2018, California State Waters Map Series—Offshore of Gaviota, California: U.S. Geological Survey Open-File Report 2018–1023, pamphlet 41 p., 9 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20181023. This map shows physical marine benthic habitats in the Offshore of Gaviota map area. Marine benthic habitats represent a particular type of water quality, substrate, geomorphology, seafloor process, or any other attribute that may provide a habitat for a specific species or an assemblage of organisms. Marine benthic habitats are classified using the Coastal and Marine Ecological Classification Standard (CMECS), developed by representatives from a consortium of federal agencies. CMECS is the U.S. government standard for marine habitat characterization. The standard provides an ecologically relevant structure for biologic, geologic, chemical, and physical habitat attributes. This map illustrates the geoform and substrate components of the standard. This map was derived from geologic and geomorphic map units by translation of the unit description into the best-fit values of CMECS classes. The CMECS classes are documented at https://www.fgdc.gov/standards/projects/FGDC-standards-projects/cmecs-folder/CMECS_Version_06-2012_FINAL.pdf. This work is of potential marine benthic habitat maps characterized after Coastal and Marine Ecological Classification Standard (CMECS). These maps will be interpreted from Bathymetry and backscatter sonar data collected along the coast of central California. This information is not intended for navigational purposes.

Davenport 2018 pamphlet and map sheets Open-File Report 2018-1023 Reston, VA U.S. Geological Survey https://doi.org/10.3133/ofr20181023 Map elements were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the lead authors and by the GIS technician(s) who created the digital database. Review drafts of the map were reviewed internally by at least two other geologists for consistency with basic geologic principles and general conformity to USGS mapping standards. Data are complete: no offshore features that could be accurately identified and represented at the compilation scale of 1:24,000 were eliminated or generalized. The smallest area represented is approximately 100 square meters. All geospatial database elements are attributed. Polygons were primarily mapped by (1) interpretation of 1-meter-resolution hillshaded bathymetry data from bathymetric lidar and sonar surveys; (2) interpretation of 1-meter-resolution amplitude (backscatter) data from bathymetric sonar surveys; or (3) interpretation of 1-meter interpretation of seismic-reflection-profile data. Map Unit contact locations were interpreted typically at a scale of between 1:1,000 and 1:2,000 using the above base data. Bathymetric sonar and lidar data have a horizontal accuracy greater than the resolution of the base data. Map unit contacts were digitized by heads-up screen digitization of line data on 1-meter-resolution DEMs described above. Horizontal accuracy is estimated to be 2 meters depending on how clearly contacts can be resolved. Most digitized positions on the map are estimated to have better than 5 m horizontal accuracy. There is no elevation data in the database. Peter Dartnell Rikk G.

Derivatives such as slope and curvature were generated from source rasters. Interpreted rasters include amplitude, hillshaded bathymetry (using various illumination angles and vertical exaggeration), slope, and curvature. Curvature was decomposed into profile and plan curvature for analysis purposes. bathymetry backscatter 2016 Metadata was modified to add accompanying USGS Open-File Report to the Larger Works section.
