Summary
This collection contains 15 1:24,000-scale surficial geologic maps throughout NH in Geologic Map Schema (GeMS) format. Specific 7.5-minute quadrangles include Bartlett, Bradford, Center Sandwich, Danbury, Hillsboro Upper Village, Jackson, Jefferson, Lancaster, Melvin Village, Mount Grace, Mount Chocorua, Mount Dartmouth, New London, Royalston, and Squam Mountains. The data preservation work in this project involved converting legacy geologic map schemas to full GeMS compliance. This dataset includes GIS surficial data for each quadrangle in the following formats: Esri geodatabase, shapefile, text, Microsoft Excel, and xml. The deliverables also include a PDF of the geologic map showing surficial geology, description of map units, explanation [...]

The deliverables also include a PDF of the geologic map showing surficial geology, description of map units, explanation of map symbols, correlation of map units, and basemap information, as well as a separate PDF of the geologic history as written by the original author. Each map folder also contains Esri MXD and style files. Data can be accessed by emailing New Hampshire Geological Survey or through the National Geologic Map Database (NGMDB) web catalog.
