<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This is a polygon feature class used to delineate the head scarp and flanks of landslides using the methods described in protocol. Only scarps and flanks visible in lidar (light detection and ranging) derivative datasets are delineated with this feature class, and no scarps or flanks inferred from aerial/orthoimagery, field reconnaissance, or other techniques are included. This feature class is part of a larger landslide inventory dataset for Washington State. Polygons in this feature class are related with polygons in the landslide_deposit feature class, and polylines in the scarp feature class, by using the LANDSLIDE_ID primary key field.</SPAN></P></DIV></DIV>
This feature class was produced to provide attribute and spatial information on landslides in Washington State. Data added will be non-regulatory and is intended for informational purposes. It may not be suitable for legal, engineering, forestry, or surveying purposes; but it is intended to assist planners, homeowners, regulators, and others by identifying areas to seek further geologic investigation in before developing, or areas to avoid. Users of this information should consider their intended application, and review or consult the accompanying documentation, to determine the usability of the data for themselves.

Up to 50 percent of the data is reviewed by senior geologists against lidar base maps and aerial/orthoimagery to ensure complete and consistent data.
As additional high quality lidar is obtained, and as mass movements occur, this inventory will continue to be revised and updated; because of these caveats this inventory may not contain all the landslide scarps and flanks within an area that mapping appears to be completed.
The scarps and flanks attributes only include unique identification number and comment attributes that can be remotely populated. The certainty of landslide scarp and flank areas are interpreted as part of the CONFIDENCE attribute within the related landslide deposit feature (related using the LANDSLIDE_ID primary key field). Attributes for up to 50 percent of the data are reviewed by senior geologists to ensure complete, correct, and consistent data.
The features are digitized at 1:4000 scale on 3 foot resolution lidar derivative datasets, which have varying horizontal accuracy depending on the project area.

The head scarp and flank areas are identified as the steeper surface of disturbed ground at the uphill edge and perimeter of a landslide where the landslide mass has moved away from the undisturbed ground (Cruden and Varnes, 1996).
