Description:
Abstract: This data set represents a 0.76-meter resolution LiDAR-derived bare earth hillshaded terrain (illumination from the northwest) layer for New Hampshire. It was generated from a statewide Esri Mosaic Dataset which comprised 7 separate LiDAR collections that covered the state as of January, 2022.
Purpose: This data set represents a 0.76-meter resolution LiDAR-derived bare earth hillshaded terrain (illumination from the northwest) layer for New Hampshire. It was generated from a statewide Esri Mosaic Dataset which comprised 7 separate LiDAR collections that covered the state as of January, 2022.
Supplemental Information: One companion data set representing a northeast illuminated hillshade (LiDAR_Derived_Bare_Earth_NE_HS_NH_2022.img) is also available from NH GRANIT.

Process Step:
Process Description: 
The ArcGIS "Hillshade" geoprocessing tool was used to produce the hillshade raster using the following parameters: input raster - outputDEM; traditional hillshade type; solar altitude angle of 315 degrees; solar aspect angle of 45 degrees; adjusted scaling; Z-factor of 1. The output hillshade was then subset using the ArcGIS "Extract by Mask" geoprocessing tool to confine the data to the New Hampshire state boundary.
Process Date: 20220708
Process Step:
Process Description: 
A combination of ArcGIS processing tools were used to combine the source rasters into a Mosaic Dataset.
