This is a GENERALIZED version of the High Plains Regional Ground Water Study.
This coverage was created for use in illustrations only. It is not suitable for spatial analysis.
Procedures_Used:
The coverage was generated by generalizing the full resolution coverage, first using ARCEDIT GENERALIZE and then using manual editing to remove some of the more intricate loops and curves in the boundary.
Reviews_Applied_to_Data:
No formal review. Working maps have been reviewed.
Related_Spatial_and_Tabular_Data_Sets:
This coverage should be used with the generalized version of the the other NAWQA study unit boundaries to give the overall national picture of NAWQA study units.
A full resolution version of this boundary also is available.
This is for internal USGS use only and is not intended for spatial analysis.
