Arcs were generated by coordinate input to define the outer boundary of the study area, and inner boundaries where 7.5 minute quadrangle boundaries occur. Boundaries at 30 minute intervals were also coded so they could be selected and plotted if a simpler graticule was desired. Purpose: The data was generated to help in understanding the seismotectonic hazards in the vicinity of the lower Wabash Valley. This data complements similar data collected in the vicinity of New Madrid, MO (US Geological Survey Open-File Report 95-0574, available via ftp at ) Status: Progress: complete Maintenance_and_Update_Frequency: none planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -89 East_Bounding_Coordinate: -87 North_Bounding_Coordinate: 39 South_Bounding_Coordinate: 36.5 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: boundary and graticule Place: Place_Keyword_Thesaurus: None Place_Keyword: Wabash Valley Access_Constraints: none Use_Constraints: none Point_of_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Susan Rhea Contact_Organization: US Geological Survey Contact_Position: Geophysicist Contact_Address: Address_Type: mailing address Address: MS966, Box 25046, Federal Center City: Denver State_or_Province: CO Postal_Code: 80225 Country: USA Contact_Voice_Telephone: 303-273-8639 Contact_Facsimile_Telephone: 303-273-8600 Contact_Electronic_Mail_Address: rhea@usgs.gov Contact_Instructions: email is the best way to make contact Native_Data_Set_Environment: SunOS, 5.5.1, sun4u UNIX, ARC/INFO version 7.1.1 Cross_Reference: Citation_Information: Originator: Rhea, Susan, and Wheeler, R.L.

Coordinates of internal boundaries were also entered by keyboard and converted to lines. Codes for the neatline and other lines were added to each line segment: > NEATCODE: 0 or 1 > MJRULCODE: 0 or 1 > MNRULCODE: 0 or 1. Note that the neatcode has all three values equal to 1, and a major rule has both MJRULCODE and MNRULCODE equal to 1.
