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.

Detailed_Description:

Entity_Type:

Entity_Type_Label: US1HZ050.PAT
Entity_Type_Definition:

1.0 second Spectral Acceleration with 10% Probability of Exceedance in 50 years

Entity_Type_Definition_Source: OFR-97-0131

Attribute:

Attribute_Label: ACC_VAL
Attribute_Definition:

Acceleration value in percent of gravity of the polygon. 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.

Range_Domain_Minimum: 0
Range_Domain_Maximum: 100
Attribute_Units_of_Measure: percent of gravity
Attribute_Measurement_Resolution: 1

Attribute:

Attribute_Label: VALLEY
Attribute_Definition:

A topological indicator that tells whether the area contained within the polygon is a local minima (valley) or not. A value of "1" indicates the area is a local minima.
