Available online at . Online_Linkage: Description: Abstract: These data are a digital version of U.S. Geological Survey Professional Paper 1183, Landslide Overview Map of the Conterminous United States. The map and digital data delineate areas in the conterminous United States where large numbers of landslides have occurred and areas which are susceptible to landsliding. Because the data are highly generalized, owing to the small scale and the scarcity of precise landslide information for much of the country, they are unsuitable for local planning or actual site selection. This National Atlas map layer was previously distributed as Digital Representation of the Landslide Overview Map of the Conterminous United States. Purpose: These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:4,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data. Supplemental_Information: The purpose of this map layer is to give the user a general indication of areas that may be susceptible to landsliding. It is not suitable for local planning or site selection. More information on the USGS National Landslides Hazards Program is available at .

Logical_Consistency_Report: Digital data were visually inspected and agree with the original manuscripts. Completeness_Report: This map layer is an overview of landsliding in the conterminous United States. The data are thematic and general in nature. There is no intention to fully describe the extent of landsliding in the conterminous United States.

Minor revisions were made to spatial and attribute information in consultation with one of the original authors (D.J. Varnes). Source_Used_Citation_Abbreviation: Coastlines Process_Date: 2000 Process_Step: Process_Description: Sliver polygons along State lines were eliminated by merging the polygons with the appropriate larger polygon to which they belonged. Adjacent polygons with the same descriptor of landslide incidence and susceptibility (inc_sus) were merged. Interior State lines were deleted and the attribution was checked. A value of 'no-data' was applied to water areas such as Puget Sound and the Great Lakes. Process_Date: 2000 Process_Step: Process_Description: Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands were removed from the file.
