This data set represents a 5-meter resolution LiDAR-derived degree slope layer for New Hampshire. It was generated
from a statewide Esri Mosaic Dataset which comprised 8 separate LiDAR collections that covered the state as of January, 2020. The Mosaic Dataset
was used as input to the ArcGIS Spatial Analyst "Slope" geoprocessing tool which calculates the degree slope for each cell of the input raster,
in this case, the statewide mosaic dataset.
This data set estimates the degree slope for pixels in the raster dataset, and is one of a suite of topographic datasets available from
NH GRANIT that convey the shape of the Earth's surface.

The critical attribute of this data is the raster cell degree slope, the absolute accuracy of which has been affected by a number of
processing steps. The original LiDAR elevation source DEMs had a 0.7 - 2 meter or better nominal post spacing (GSD).

Data are complete for the State of New Hampshire, and reflect the content of the source datasets.
The ArcGIS "Slope" geoprocessing tool was applied to BAREERTHDEM along with the "DEGREE" option to generate an interim slope layer. The
interim slope layer was then projected to the NH Stateplane spatial reference system.
