This GeoTIFFs represents ground elevation and ground intensity of the northwest portion of the outer north-west of the Mackenzie Delta 2008, Northwest Territories, Canada. It is derived from LiDAR (Light Detection and Ranging) data acquired by Advanced Geomatics Research Group (AGRG), Nova Scotia Community College (NSCC) in partnership with Natural Resources Canada and Environment Canada. The source of the gridded LiDAR elevation data is cleaned ground-classified LAS point files containing elevation and intensity values. Data were collected using the ALTM 3100-C LiDAR system. Vertical readings are accurate to within 30 cm. Elevation heights are transformed to the Canadian Geodetic Vertical Datum of 1928 (CGVD28) using height transformation version 2.0 (HT2.0). These data were collected using differential Global Positioning System (GPS) which determines the position of the aircraft with an accuracy of 30 centimetres.

The data will be used as a tool to help accurately predict coastal storm surge and spring freshet flooding levels, morphological characterization, and to provide a baseline for future erosion and sedimentation/subsidence studies. : Summary: Not Applicable
