Metadata: Identification_Information: Citation: Citation_Information: Originator: U.S. Geological Survey Publication_Date: 1997 Title: Hazard maps of the U.S. Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: U.S. Geological Survey Open-File Report Issue_Identification: 97-131 and 97-130 Online_Linkage: ftp://hazards.cr.usgs.gov/hazmaps/gis/ Description: Abstract: The coverages were created using the gridded data available from this ftp site. Most of the gridded data for the United States is at a spacing of 0.1 degrees latitude and longitude. The higher resolution data available for California, Nevada, and part of Arizona and Utah were used for both the U.S. and Western U.S. maps. The gridded data for this area is at a spacing of 0.05 degrees latitude and longitude. Purpose: To provide to the public a digital hazard map database of the United States.

The polygon represents the range of acceleration values that are contained within its borders. The polygon is assigned the lowest value allowed within the polygon's borders. The range of values allowed within a polygon is controlled by the contours.
