LiDAR Products

LiDAR is an acronym for Light Detection and Ranging. It is a technology that utilized lasers to determine the distance to an object or surface. Lidar is similar to radar, but incorporates laser pulses rather than sound waves. It measures the time delay between transmission and reflection of the laser pulse. LiDAR is used in a variety of industries such as atmospheric physics, geology, forestry, and oceanography. We utilize it primarily as a source for creating three dimensional topographic maps.

This page provides a portal to various LiDAR derived products that are used in our research activities. Click on the links below to go to the respective pages to access the data.

LiDAR Data Access

Connecticut LiDAR 10-foot DEM

This DEM dataset represents 10-foot spatial resolution elevation information for the state of Connecticut. The data are derived through the spatial interpolation of airborne LiDAR collected in the year 2000. The point files have been edited to remove anomalous observations, but given the volume of data, there are likely errors still present in the point data as well as in the interpolated surface. The elevation data are in a gridded (TIFF) format and are projected into the State Plane Coordinate System Zone 0600, orthometric heights (NAVD 88) in US Survey feet. Data can be downloaded as USGS topgraphic quadrangles or by town.

Connecticut LiDAR Derived Products

This statewide dataset consists of LiDAR-derived data products generated from Connecticut's 2000 statewide LiDAR coverage. Derived products include tiled point clouds, TINs, DEMs, and contour shape files. No editing has been performed to remove anomalous observations. This is a Beta product and intended for research and demonstration purposes only. Data can be downloaded as USGS topgraphic quarter-quarter quadrangles.
