Identification_Information:Identification_Information: Citation: Citation_Information: Originator: New Hampshire Department of Environmental Services Publication_Date: 20010101 Title: Bedrock geologic units of New Hampshire Geospatial_Data_Presentation_Form: vector digital data Online_Linkage: http://pubs.usgs.gov/ds/215 Description: Abstract: These data contain polygon features digitized from the Bedrock Geologic Map of New Hampshire (Lyons and others, 1997). The bedrock geologic map displays the type, location, and geologic age of the rocks underlying the state. The map is a compilation of decades of work by geologists who mapped individual portions of the state at various times. Polygon features found in these data display the location and extent of each mapped bedrock body in the state at a scale of 1:250,000. Purpose: The dataset is intended to provide general locations and characterizations of bedrock units to enable spatial analyses and comparisons of bedrock types to be performed by geologists, engineers, planners, and the public.
