Note: To unzip the DTM/DSM/nDSM you will need to download the WinRAR software.  We were unable to zip these layers because the layers are in excess of 4 gigabytes, which is the limit of files having the ability to be zipped.

1. DTM:
A DTM is a 'bare earth' elevation model, unmodified from its original data source (such as lidar, ifsar, or an autocorrelated photogrammetric surface) which is supposedly free of vegetation, buildings, and other 'non ground' objects.

2. DSM:
A DSM is an elevation model that includes the tops of buildings, trees, powerlines, and any other objects. Commonly this is seen as a canopy model and only 'sees' ground where there is nothing else overtop of it.

3. nDSM:
A nDSM depicts the difference between the digital surface model (DSM)—which reflects the highest points of objects (tops of structures, vegetation)—and the digital elevation model (DEM), which reflects the underlying “bare earth”.  Essentially a nDSM is a height of objects on the ground.

4. Elevation Contours_2ft:
2ft contours derived from 2020 LiDAR

5. Steep Slopes:
Classified slope data depicting steep slopes (15-25% and 25% +)

6. LiDAR Point Cloud
At this point, the 2020 point cloud data can not be downloaded due to its sheer size.  In the meantime, the 2017 LiDAR point cloud data can still be downloaded:
