Abstract:
This data set is a GIS version of part of the Alberta Geological Survey's published Map No. 227, which in turn is a regional synthesis of various published and unpublished maps. The data represent drift isopachs for Alberta.
Purpose:
For depicting the drift thickness (i.e., thickness of unconsolidated sediments overlying bedrock) at a 1:2 000 000 scale.
Supplemental Information:
The southern part of the province, from 49 to 56 degrees North, was primarily compiled from existing 1:250 000 bedrock topography maps. The interpretation of the remaining northern portion of the province was based mostly on limited borehole data and information from existing 1:250 000 hydrogeological maps. The exposed areas represent areas where drift is absent or thin and discontinuous. Contour intervals are irregular and depend on local data density.

Process Description:
Digital MCAD files of drift thickness contours were exported to DXF format using Canvas 3.5.5 and CorelDraw 8.0, imported into ArcInfo 7.2, then georeferenced using the Arc TRANSFORM command. Line features were tagged with drift thickness using ArcInfo 7.2 and/or ArcView 3.2a.
