<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This is a polygon feature class used to delineate landslide deposits using the methods described in the report accompanying these data. Only landslide deposits visible in lidar (light detection and ranging) derivative datasets are delineated with this feature class, and no deposits inferred from aerial/orthoimagery, field reconnaissance, or other techniques are included. This feature class only includes attribute fields the analyst can populate remotely. 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 scarps_and_flanks feature class, and polylines in the scarps feature class, by using the LANDSLIDE_ID primary key field.</SPAN></P></DIV></DIV>
These data were produced to provide attribute and spatial information on landslides in Washington State. This data is 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 deposits within an area that mapping appears to be completed.
The landslide deposit attributes only include data that can be remotely populated. Additionally, an attribute field (CONFIDENCE) is included to interpret the confidence of the landslide based on a scale of identification (not identifiable=0 to clearly identifiable=10) for four criteria: 1) head scarp; 2) flanks; 3) toe; and 4) internal morphology (irregular or hummocky surface). 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.
