Name: Landslide Deposit

Display Field: LS_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This is a polygon feature class used to delineate landslide deposits using the methods described in our lidar-based protocol (Slaughter and others, 2017). Only landslide deposits visible in lidar 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 information the landslide analyst can determine 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 lines in the ‘Scarps’ feature class, by using the LANDSLIDE_ID primary key field.
