Service Description: This dynamic layer provides elevation data from the 2020 Northern Shenandoah lidar collection, which took place between 11/29/2020 and 1/12/2021. Different visualizations can be created through the use of raster functions applied to the source data. The surfaces available for raster functions include a high-resolution digital elevation model (DEM) and a digital surface model (DSM) to model bare earth or above ground surfaces.
Layer Applications
Use for Visualization: Yes, this is the primary layer use. Bare earth and above ground surfaces can be modeled using the different raster functions available in the symbology pane.
Use for Analysis: No, this layer should not be used for analysis workflows.
How was this made?
Lidar point clouds were processed in ArcGIS Pro to generate a DEM and DSM with a cell size of 0.5 meters. The raster surfaces were then loaded into a mosaic dataset built using a source/derived management style. Then, raster function template files were generated and applied to the rasters, allowing the hillshade surfaces to be created. These surfaces are highly accurate in terms of spatial location and depicting the earth's surface at the time of collection.
