Abstract

The digital product contains 48 shaded relief images that are each provided in MrSID and JPEG formats. These images are produced from a 100 meter gridded Digital Elevation Model (DEM) with the sun shining along 8 different azimuths (0, 045, 090, 135, 180, 225, 270, 315) at 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 NSDNR, Mineral Resources Branch (MRB) staff. The shaded relief images were derived from a DEM provided by the Nova Scotia Geomatics Center (see cross reference 1 for DP ME 55).

The Mineral Resources Branch has produced a number of shaded relief images in MrSID format for the province, gridded at 25 metres (DP ME 56), which can be downloaded for free as digital product DP ME 56. MRB has produced a map (OFM ME 2004-1) that shows how the shaded relief images contained in DP ME 56 and DP ME 57 were created and provides an example of the effect of changes in azimuth and altitude on the appearance of the image. This map can be downloaded for free as digital product DP ME 105. Metadata about the DEM used to create DP ME 56, 57 and 105 can be downloaded as digital product DP ME 55.
