Abstract
The digital product contains 48 shaded relief images that are each provided in MrSID format. These images are produced from a 25 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
an Enhanced Digital Elevation Model 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 JPEG and MrSID format for the province,
gridded at 100 metres (DP ME 57), which can be
downloaded for free as digital product DP ME 57.
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. |
