The original files are named 250kmaps and 50kmaps, and both were downloaded in arc.shp format. The files represented the NTS index maps in polygon form with attributes across Canada. The attribute tables contain information on the NTS mapsheet name and number.
The files were stripped down to Saskatchewan jurisdiction. The shapefiles within the project were initially projected to a lambert projection, NAD83 datum with the following parameters: 1st standard parallel: 49o 2nd standard parallel: 77o central meridian: 95o W Latitude of projection's origin: 49o false northing: 0 false easting: 0
ReProjection: The Lambert projection files of the Saskatchewan region have been reprojected by ISC to Universal Transverse Mercator to match other Saskatchewan data. The UTM projection is to Zone 13 on NAD83.
The reprojection was done using arcview 3.1 and the prjctr.avx extension. A good description on the use of this extension can be found at the Wyoming Bureau of Land Management site at <http://www.wy.blm.gov/gis/projector.html> for those that may want to convert to other projections.
