Connecticut Lidar Data (2014-2006)

 

Connecticut is covered by a number of different lidar datasets. They were captured by different vendors with different specs at different times. The image services of the elevation data show topography, hillshade, slope and aspect.

CT ECO does not provide download for these lidar datasets. If the data is available for download elsewhere, it is noted.
