<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This data set represents a 2-meter resolution LiDAR first return surface or Digital Surface Model (DSM) for New Hampshire. It was derived  from a statewide LAS Dataset which comprised 8 separate LiDAR collections that covered the state as of January, 2020. The LAS Dataset  was used as input to the ArcGIS "LAS Dataset to Raster" geoprocessing tool which converted the LAS first return values to  raster values in the output data set.    In some areas, users may notice unusual linear edges which appear unlikely or anomalous. The LiDAR vendor explained that these anomalies may be  the result of changes in the degrees of tree canopy closure that occurred between the times adjacent flight lines were completed. Although leaf-off  conditions were specified for data collection, strict adherence to the project specifications was not possible in all locations and exceptions  occurred in order to complete data acquisition in a timely manner. As a result, abrupt discontinuities may be noticeable where data were collected  on different dates. Eamples of these anomalies can be found in the areas of Cave Mountain in Bartlett and to the west of Woodstock.</SPAN></P></DIV></DIV>
