These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to aid in assessments and mitigation of geologic hazards in the central California coastal region and to provide sufficient geologic information for land-use and land-management decisions both onshore and offshore.

Landslide features were primarily mapped by interpretation of seismic reflection profile data.
Landslide features were digitized by heads-up screen digitization on to shot point picks from seismic
line navigation data - each shot point has an associated lat/long in the survey data. Error is introduced
from layback, as well as from interpretation of oblique features, so horizontal accuracy of Landslide features
location is estimated to be on the order of 10 to 20 meters.
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.
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.
Are there legal restrictions on access or use of the data?
- Access_Constraints:
- If physical samples or materials are available, constraints on their on-site access are described in "WR CMG Sample Distribution Policy" at URL: <http://walrus.wr.usgs.gov/infobank/programs/html/main/sample-dist-policy.html>
- Use_Constraints:
- This information is not intended for navigational purposes.
Read and fully comprehend the metadata prior to data use. Uses of these data should not violate the spatial resolution of the data. Where these data are used in combination with other data of different resolution, the resolution of the combined output will be limited by the lowest resolution of all the data.
