Description:
Abstract:
USGS map quandrangle boundaries with names and unique identifiers for the 1:24,000 (7.5 minute) quadrangles. Additional attributes provide unique identifiers and hierarchical relationships between these quadrangles and the enclosing 1:100,000 (30 x 60 minute) and 1:250,000 (1 x 2 degree) quadrangles.
Purpose:
The data set is intended to facilitate georeferencing scientific sampling localities by providing a named and coded reference system with which some people may already be familiar.

Data_Set_Credit:
Jeff Grossman created the coding scheme relating quadrangles of various scales
Native_Data_Set_Environment: Originally creating using ArcView 3.3
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Names of the quads were given in the source data; rare corrections have been made where noticed. Codes are mostly calculated from the coordinates but in some cases were created by examining the published (paper) quad map indexes produced by USGS on a state-by-state basis.
Logical_Consistency_Report:
As far as is practical, the names match those given in the printed (paper) map indexes produced by USGS. The numerical codes for the 1:250,000-scale quadrangles differ from those shown in some USGS map indexes because the point of reference is here taken as the northwest rather than the southeast corner of the quadrangle.
Completeness_Report:
All 1:24,000 quadrangles currently available (as of 2004) were included.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: Coordinate values are normally computed rather than measured.
