Description: <p>This layer is a modified version of the 1:24K USGS DLG-derived political boundaries datalayer provided by NH Granit. &nbsp;Subtle deviations in the linework between this layer and Granit's reflect, 1) NRPC's adoption MassGIS's representation of the state boundary between New Hampshire and Massachusetts using survey points, and, 2) areas where town-originated digital parcel data overlapped, in which case the placement of the town boundary is at the estimated midpoint of the overlap, and the digital parcels were then edge-matched accordingly. &nbsp;</p><p>More significant discrepancies reflect NRPC's corrections of the town boundaries along two key areas:&nbsp;<br>•&nbsp;&nbsp;&nbsp;&nbsp;The northern border between Pelham and Hudson: NRPC's depiction agrees with local perambulation records and was reaffirmed through the Towns' joint submission to the U.S. Census Boundary Annexation Survey in 2017. &nbsp;<br>•&nbsp;&nbsp;&nbsp;&nbsp;The Summer Street area between Milford and Amherst: &nbsp;NRPC's data reflects the outcome of NH Legislation, HB 1248 (2006), which transferred a portion of territory from Amherst to Milford. &nbsp;</p><p>Lastly, it should be noted that NRPC's mapping of the entire western border of Lyndeborough along Greenfield and Temple reflects the definition of the town line according to the town's digital parcels provided to NRPC by Cartographic Associates in 2015. &nbsp; It diverges profoundly from the border representation in NH Granit and also U.S.Census (which also differ from each other).&nbsp;</p><p>Disclaimer: This dataset is an NRPC interpretation of original source material and maps.
