Description:
Abstract:

This dataset is a GIS version of part of Map 227, which is a regional synthesis of various published and unpublished maps. The data represent drift isopachs for Alberta.

The southern part of Alberta, 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.

Purpose:
For depicting the drift thickness (i.e., thickness of unconsolidated sediments overlying bedrock) at a 1:2 000 000 scale.

Data Quality Information:
Logical Consistency Report: Arcs represent isolines and therefore do not cross. There is no directionality to the lines.
Completeness Report:
The original map shows no drift in the disturbed belt nor on the shield. there are no isolines in those parts of the province.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: No formal accuracy check completed; digital accuracy estimated at +/- 5 km.
Lineage:
Process Step:
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.
Process Date: 2002
Process Step:
Process Description:
Edited the data as many arcs were wrongly coded. Unsplit the lines, corrected many thickness values to match original map.
