Connecticut Elevation Lidar Data Elevation information is scattered around the website and this web page puts it all in one place.
Viewers 3D Lidar Point Viewer View and interact with the color Lidar point cloud in a 3D web scene Elevation Viewer The bare earth raster tiles are part of the online, interactive elevation viewer that contains elevation, hillshade, shaded relief, slope and aspect.
Elevation Interact Viewer For intermediate users, seven elevation datasets in one map with image display options. Information and Help What is Elevation Data?
These data gaps are a know limitation in the foot posting LiDAR data collected for Connecticut during the year Are there legal restrictions on access or use of the data? Access constraints: None. No restrictions or legal prerequisites for accessing the data. The data is in the public domain and may be redistributed. No restrictions or legal prerequisites for using the data after access is granted. This information may be incorrect in some areas due to gaps in the underlying point elevation LiDAR data used to generate the hillshade effect.
When displayed at a detailed map scale, the hillshade will appear discontinuous in areas where information is incorrect, and linear breaks in the hillshade become apparent in areas where there are errors in the underlying elevation data.
Due to these anomalies and inconsistencies, use caution when viewing and analyzing this informaiton. Who distributes the data set?
