This image service is available through CTECO, a partnership between UConn CLEAR and CT DEEP. This layer is a hydro-flattened bare earth digital elevation model (DEM) derived from the classified Lidar point cloud covering the state of Connecticut.NOTE Service ChangesAlthough currently displaying 2023 elevation, this service (called Elevation) previously displayed 2016 elevation and will be updated when new elevation is available. Visit the CT ECO Map and Image Services page for a complete list of available elevation services. Connect to this service when you always want the latest and greatest service. Connect to CT 2023 Elevation (DEM) service for 2023 elevation that will not change. 2023 Statewide Extent: ConnecticutDates: 2023 (March 27 - April 13), between snow melt and leaf outData Info: statewide Digital Elevation Model (DEM), which is a bare earth elevation raster with no functions applied Pixel Resolution: 2 foot DEM raster derived from QL1+ Lidar point cloud with a minimum of 15 points per square meter inland and 20 points per square meter along the coast. The bare earth elevation from the points were averaged to get the elevation value for each pixel in the DEM. Projection: CT State Plane NAD 83 (2011) Feet (EPSG 6434)Service Projection: WGS 1984 Web Mercator Auxiliary Sphere (EPSG 3857)More Information- All About the 2023 Data Collection (Imagery and Lidar)- All about Connecticut Lidar Elevation- Lidar Elevation on CT ECO Explained- Metadata xml formatTips- The elevation service contains processing templates like hillshade, slope, and aspect, that can be applied to change the appearance of the layer. - Symbology is another useful and easy way to display the elevation differently.
