<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This is a point feature class used define the approximate head scarp or initiation area of landslides using the methods described in the protocol. Recent landslides visible in aerial/orthoimagery, from lidar, from field reconnaissance, or from information from outside sources are defined with this feature class. This feature class only includes attribute fields the analyst can populate remotely or from reconnaissance-level field mapping. This feature class is part of a larger landslide inventory dataset for Washington State.</SPAN></P></DIV></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 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 within an area that mapping appears to be completed.
The landslide scarp attributes only include unique identification numbers and comments that can be remotely populated. The certainty of a landslide scarp is 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 features are digitized at 1:4000 scale on 3 foot resolution lidar derivative datasets, which have varying vertical accuracy depending on the project area.
The landslide scarps are mapped following the methods in Protocol for Landslide Inventory Mapping from Lidar Imagery (Slaughter and others, 2017).

Recent Landslide Points
Recent Landslide Points are generally small, and primarily shallow-seated landslides that are visible in aerial/orthoimagery and (or) in the field but are not visible in lidar derivative datasets (Slaughter and others, 2017).
