This layer is lidar point intensity covering the state of Connecticut. <div><br /></div><div><b>Lidar intensity</b> is a measure of the return strength of each lidar point. Here, the points are converted to 1 foot pixels and values range from 1-256 where low numbers are low reflectivity and high numbers are high reflectivity. Intensity in influenced by reflectivity of the surface at the sensor wavelength (here, 1064nm which is near-infrared), view angle, range, surface composition, roughness, and moisture content and should therefore be used as a relative measure. Intensity is not influenced by sunlight or shadows. <div><br /></div><div>Visit the CT ECO <a href='https://maps.cteco.uconn.edu/map-services/#elevation' target='_blank' rel='nofollow ugc noopener noreferrer'>Map and Image Services </a>page for a complete list of available elevation services. </div><div><div><br /><div><div><font color='#104c9b'><b>Dataset Information</b></font><br /></div><div><div><b>Extent:</b> Connecticut</div><div><b>Dates:</b> 2023 (March 27 - April 13), between snow melt and leaf out</div><div><b>Data Info:</b> statewide raster of lidar point density</div><div><b>Pixel Resolution: </b>1 foot pixel 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. </div><div><b>Projection: </b>CT State Plane NAD 83 (2011) Feet (EPSG 6434)<br /></div></div><div><b>Service Projection:</b> WGS 1984 Web Mercator Auxiliary Sphere (EPSG 3857)<br /></div><div><br /></div><div><b><font color='#104C9B'>More Information</font></b></div><div>- <a href='https://maps.cteco.uconn.edu/data/flight2023/' target='_blank' rel='nofollow ugc noopener noreferrer'>All About the 2023 Data Collection</a> (Imagery and Lidar)</div><div>- <a href='https://maps.cteco.uconn.edu/data/lidar/' target='_blank' rel='nofollow ugc noopener noreferrer'>All about Connecticut Lidar Elevation</a></div><div>- <a href='https://maps.cteco.uconn.edu/data/lidar/elevation_explained/' target='_blank' rel='nofollow ugc noopener noreferrer'>Lidar Elevation on CT ECO Explained</a></div><div>- <a href='https://cteco.uconn.edu/download/metadata/CT_DEM_2023_metadata.htm' target='_blank' rel='nofollow ugc noopener noreferrer'>Metadata</a> <a href='https://cteco.uconn.edu/download/metadata/CT_DEM_2023_metadata.xml' target='_blank' rel='nofollow ugc noopener noreferrer'>xml format</a></div><div>- <a href='https://maps.cteco.uconn.edu/download/' target='_blank' rel='nofollow ugc noopener noreferrer'>Download DEM and points</a></div><div><br /></div><div><b><font color='#104C9B'>Credit and Funding</font></b></div></div></div><div><b><font color='#104C9B'><br /></font></b></div></div></div>
