Service Description: This data set represents smoothed, 2-foot bare earth contours (isolines) for the Upper Connecticut-Mascoma (01080104) HUC 8 unit. It was derived from a data set which was compiled from LIDAR collections in NH available as of spring, 2019. The raster was filtered using the ArcGIS FOCAL STATISTICS tool with a 3x3 circular neighborhood. The contours were generated using the ArcGIS CONTOUR tool while applying a Z factor of 3.2808 to convert the elevation values from meters to feet. The filtered contours were then smoothed using the ArcGIS SMOOTH LINE tool. The data include an INDEX field with values of 10 and 100 to flag 10 and 100-foot contours. When viewed using this service, contours become visible at scales greater than 1:10,000.

Title: Two Foot Topographic Contours - Upper Connecticut-Mascoma (01080104) - smoothed
Author: NH GRANIT
Comments: This data set represents smoothed, 2-foot bare earth contours (isolines) for the Upper Connecticut-Mascoma (01080104) HUC 8 unit.

Subject: These contours connect points of equal elevation at 2-foot intervals, and are one of a suite of topographic datasets available from NH GRANIT.
