Layers:

Layer: Fans (5)


Name: Fans

Display Field: FAN_ID

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This is a polygon feature class used to delineate alluvial fan or debris flow fan deposits using the methods described in our lidar-based protocol (Slaughter and others, 2017). Fans visible in lidar (light detection and ranging) derivative datasets are delineated in this feature class, and no deposits inferred from aerial/orthoimagery, field reconnaissance, or other techniques are included. This feature class only includes information the analyst can determine remotely. This feature class is part of a larger landslide inventory dataset for Washington State.
