___Bedrock well yield, ancillary data, and lineaments in the Nashoba terrane, central and eastern Massachusetts
Lineaments from three data sources were identified in the Ayer, Hudson, Marlborough, and Westford 7.5 x7.5 minute quadrangles in eastern Massachusetts. The imagery sources were high-altitude (1:80,000) black and white aerial photographs (80K), color-infrared (1:58,000) aerial photographs (CIR), and shaded Digital Elevation Model data (Shaded DEMs). One data layer from each source contains all lineaments identified by either of two independent observers (All) and another data layer contains only lineaments identified independently by both of the two observers (Coincident).
Estimated yield of bedrock wells in grid cells of 200x200 meters was determined by ordinary kriging of well yield data from 7,287 wells in the Nashoba Terrane and surrounding area, central and eastern Massachusetts, as described in U.S. Geological Survey Scientific Investigations Report 2012-5155 by DeSimone and Barbaro (2012). Two data layers are provided, estimated well yield and standard error of the estimated well yield. The values in this data set are depicted in figure 32 of DeSimone and Barbaro (2012).
