Department of Environment Spatial Data
Base or Framework Data
These datasets are administrative units created by the Department of Environment and are used in the management of Yukon's wildlife. The data are in the ESRI Shapefile format. which are in turn compressed into a Zip archive. GIS software is needed to view shapefiles.
Yukon Digital Elevation Model
A
Digital Elevation Model (DEM) spanning the entire Yukon and a bit beyond
in some places. It was interpolated from the digital 1:50,000 Canadian
National Topographic Database contour and watercourse layers using 30
meter cells (aka pixels) and then resampled to 90 meters. For refinement
and added quality we also incorporated ancillary data not part of the NTDB.

Shaded Relief Images
Also
known as Sunshade or Hillshade images, shaded relief images are the most
popular form of visually representing a DEM. Indeed many view a shaded relief
image and mistakenly think they are seeing the DEM itself. A shaded relief
image does not contain elevation values, rather each pixel's brightness
value is an expression of it's reflectance (slope and aspect) relative to
the light source (azimuth and zenith). Shaded relief is available for the
entire territory in 30m and 90m versions. (...

50k NTDB Errata
In
the course of generating the Yukon DEM we encountered and fixed errors in
the source 1:50,000 NTDB. A listing of these errors and what we did to fix
them can be downloaded from ftp://ftp.geomaticsyukon.ca/DEMs/errata/
