Description:
Abstract:
This GIS dataset depicts the locations of thalwegs (paleo-channels) incised in the bedrock surface of NTS map area 84M (line features). The data are created in ArcGIS and output for public distribution in shapefile formats.
Purpose:
For depicting the thalwegs of paleo-drainage systems in the Bistcho Lake area (NTS84M) in GIS format.
Supplemental Information:
These data comprise the thalweg line features of Map 416, Bedrock Topography of Bistcho Lake Area, Alberta, (NTS 84M). This metadata record was generated based on the ArcGIS shapefile. In English.

Data Quality Information:
Logical Consistency Report:
Visual checks have been made of the data by the author and plotted versions of the data have been checked by a third party. Line directions match flow direction, features are attributed.
Completeness Report: Thalweg data are shown only for the major buried valleys.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
Since the thalweg represents a geological interpretation, its absolute positional accuracy cannot be determined. However, the thalweg line is estimated to fall within 250 m of the bedrock low, as depicted on the bedrock topography map.
Lineage:
Process Step:
Process Description:
The thalwegs were digitized in the paleoflow direction in ArcMap after completion of the bedrock topography contouring.
