SHARED_FP.slpstab - Comparison of GIS-based Models of Shallow Landsliding for Application to Watershed Management

Data format: SDE Raster Dataset

File or table name: SHARED_FP.slpstab

Coordinate system: Lambert Conformal Conic

Theme keywords: slope stability, landslides, predictive modeling

Abstract: This coverage is a predictive data layer of shallow-rapid slope stability using one or more calibrated GIS-based models. This grid covers all forested watersheds of western Washington State. This data layer is an anticipated outcome of the Forestry Module negotiations as outlined in the Forest and Fish Report (1999) and legislated in the Engrossed Substitute House Bill 2091 (1999).

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Description:
Abstract:
This coverage is a predictive data layer of shallow-rapid slope stability using one or more calibrated GIS-based models. This grid covers all forested watersheds of western Washington State. This data layer is an anticipated outcome of the Forestry Module negotiations as outlined in the Forest and Fish Report (1999) and legislated in the Engrossed Substitute House Bill 2091 (1999).

Purpose:
The purpose of this dataset is to be a screen for determining shallow-rapid landslide potential.
It is intended to be used for pre-classification screeening of forest practices applications and 
screening for slope stability concerns on managed timberlands.

Supplemental information:
This data is derived from calibrated algorithms (models) that use DEMs to
generate slope and curvature information.  The models used are  SMORPH and
SHALSTAB.  The stated resolution of the data is tied to the resolution of the DEM
available in the area.   Additionally, other information, such as landslide
inventories, soils, mass wasting units, geology, and precipitation amounts are
used in the calibration of these models to a specific area.  These landslide data were
collected at a variety of scales, over a large period of years.  The horizontal accuracy of the grid coverage is dependent on the resolution of the Digital Elevation Model (DEM) from which it was derived.  Better information
is obtained with higher resolution DEMs.  In those areas where a 10 meter DEM
was  available, the accuracy is +/- 35 feet.   At present, 10 meter resolution data are available for most of western Washington. As better DEMs become available, the model may be rerun in those areas and will update the existing coverage.

Attribute accuracy:
Attribute accuracy report:
modeled shallow rapid slope stability:  tests (Shaw & Vaugeois, 1999) show that 93% of shallow rapid type landslides 
occur in areas modeled with a high (value = 3) probability of instability.

no model accurately predicts where deep seated landslides are going to occur

Positional accuracy:
