Abstract

This digital product consists of 144 shaded relief images derived from three contiguous LiDAR bare-earth Digital Elevation Models (DEM) of the Cobequid Highlands of Nova Scotia. The DEMs were gridded at 1m cell size from three areas of a survey carried out in December, 2010. Images were processed at 8 shading azimuths (0, 045, 090, 135, 180, 225, 270, 315) and 3 different altitudes (30°, 45°, 60°). The images were produced with two different vertical exaggerations (5 and 10).

The digital product was created by the Nova Scotia Department of Natural Resources, Mineral Resources Branch (MRB) staff.

The original DEM processing and creation was done by Leading Edge Geomatics from December 11, 2010 to March 21, 2011 and was supplied to MRB in a number of raster formats. The bare-earth DEM has buildings and vegetation removed. The XY Positional accuracy is 0.5 m along and across track and the overlap between lines was 50%. The point density was a minimum 1 point per square metre with a vertical accuracy of 15 cm (95% of the time for open cleared flat areas). The LiDAR capture was done in leaf-off conditions, with no snow or only a very thin snow cover.

Funding for this product was provided by the Government of Canada, Natural Resources Canada under the Methodology Developments Project of the Targeted Geoscience Program 4 (TGI-4). The Cobequid Highland LiDAR survey is a collaborative project between the Geological Survey of Canada and the Nova Scotia Department of Natural Resources.
