Abstract: This data set represents raw, 2-foot bare earth contours (isolines) for the Headwaters Lamprey River unit. The data set was extracted from a regional elevation contour data set derived from the Coastal New Hampshire LiDAR collection (2011). Prior to contour generation, the regional LiDAR raster was "smoothed" using the ArcGIS "Focal Statistics" tool using a 3x3 circular neighborhood. The contours were generated using the ArcGIS "Contour" tool while applying a Z factor of 3.2802 to convert the elevation values from meters to feet. Once generated, contours less than 1 meter in length were deleted.
