Connecticut Elevation (LiDAR) Data

 

There are two, statewide, lidar-based elevation datasets for Connecticut. The newest was captured in the spring of 2016 along with imagery. The second is a virtual mosaic of eight lidar datasets captured mostly between 2010 and 2014 with a few areas going back to 2006.

Both datasets include a statewide digital elevation model (DEM) that can be displayed as hillshade, shaded relief, slope or aspect.
