Description Abstract Scientists at the Cascade Volcano Observatory have completed hazard assessments for the five active volcanoes in Washington. The five studies included Mount Adams (Scott and others, 1995), Mount Baker (Gardner and others, 1995), Glacier Peak (Waitt and others, 1995), Mount Rainier (Hoblitt and others, 1995) and Mount St. Helens (Wolfe and Pierson, 1995). Twenty Geographic Information System (GIS) data sets have been created that represent the hazard information from the assessments. The twenty data sets have individual Open File part numbers and titles as listed below

Purpose The purpose for each data set varies, please see individual metadata for appropriate purpose and use.

Supplemental_Information Procedures_Used This data set was created by the CREATE command. A single polygon was added to the coverage to export in the Spatial Data Transfer Standard (SDTS). See individual data sets for procedures used. Each of the data sets was digitized from mylar or clear film stable base materials except for tephra hazards for Mount Rainier that were imported from in-house software. Metadata for each data set indicates scales for which the data should be used and is also the scale of the source maps. Root mean squared errors for both digitizing and transformations were evaluated (Environmental Systems Research Institute, 1992, p. 4-23).
