<DIV STYLE="text-align:Left;"><DIV><P><SPAN>The data in this raster depicts landslide susceptibility at a 10-meter resolution, across the state of Oregon. This dataset was created using elevation data, first from the Oregon Lidar Consortium (OLC), or from USGS NED where OLC data was not present. This elevation data was converted into slopes, and a multi-pronged analysis process used these slopes, geology and mapped existing landslides to create this 10-meter raster. There are 4 classes of landslide susceptibility: Low, Moderate, High and Very High.</SPAN></P></DIV></DIV>
This raster image depicts the landslide susceptibility through the State of Oregon. The landslide susceptibility is categorized by a low, moderate, high, and very high designation. The intended use of this overview map is to help identify regions (cities, counties, communities, portions of lifelines, watersheds, etc.) that may be at risk for future landslides. It is designed to provide landslide hazard information for regional planning and specifically to identify areas where more detailed landslide mapping is needed.

QA/QC was conducted by comparing this data set to recent, detailed mapping, on the basis of visual comparison. This comparison appeard to reasonably capture the landslide inventory and the detailed moderate and shallow slides from previous localized studies.
This data set was created and finalized for the entire state of Oregon.
This map is based on three primary sources: a) landslide inventory, b) generalized geology, and c) slope. Factors that can affect the level of detail and accuracy of the final susceptibility map include: 1) lack of detailed landslide inventory statewide, 2) too much or too little generalization of the geology, and 3) highly variable DEM resolution resulting in variable accuracy of the slope model. Refer to DOGAMI Open File Report O-16-02 for more details on primary sources.
This data set was created using generalized statewide geology and landslide inventory, both developed from multiple sources and at variable scales, and statewide digital elevation model developed from various sources and resolutions. This map is not intended to be used at scales other than the published map data scale (1:500,000). See DOGAMI Open File Report O-16-02 for more details.
Final map was created using a mosaic of Lidar-derived digital elevation models collected between 2000 and 2016 (down-sampled to 10-meter resolution) and the USGS National Elevation Dataset (10-meter resolution). See DOGAMI Open File Report O-16-02 for more details.
See accompanying report for data sources. Detailed methodology can be found in DOGAMI Open File Report O-16-02
