The geologic data was mapped during the summer of 1998 at a scale of 1:24,000. The bedrock geology was mapped using standard techniques. Locational information was provided by Rockwell PLGR+96 GPS receivers using the federal precise positioning service. The line and polygon data were compiled on a mylar greenline of the 7.5-minute quadrangle and scanned at 400 dpi on an Anatech Eagle 4080T scanner. The raster files (TIF) were converted to vector files (DXF) using GTX OSR version 2.0 raster-to-vector conversion software. The vector files were imported to Arc/Info version 7.0.4. Point data were collected with GPS and hand held 3COM Palm Pilot III PDA computers. Data from the PDAs were combined in Microsoft Access, and then imported as ASCII text files and (dbf) files into Arc/Info. The Arc/Info coverages were registered and transformed to the New Hampshire State Plane Coordinate system. Purpose: The map was published as part of a study of the fractured bedrock aquifers in the state of New Hampshire. The digital data are intended for use by all government, academic, commercial, or other agencies in need of digital geologic map information. Not intended for use at scales larger than 1:24,000. Supplemental_Information: The geology dataset was printed and visually reviewed by the map authors and other USGS staff for geologic integrity, completeness, and accuracy of linework. The report received a standard internal peer review as per USGS Open-File Reports. Access_Constraints: Neither the United States Government nor any agency thereof, nor any of their employees, make any warranty, expressed or implied, or assumes any legal liability or responsibility for the accuracy, completeness, or usefulness or any information, apparatus, product or process disclosed in this report, or represents that its use would not infringe privately owned rights.

This geologic map is a guide to the bedrock geology at 1:24,000 scale, but it is not a substitute for site specific data.
