Description:
Abstract:

This GIS dataset depicts the surficial geology of the Chipewyan Lake area (NTS 84A/NW) (discontinuous permafrost features). The data were created in geodatabase format and output for public distribution in shapefile format.

These data comprise the permafrost polygon features of Alberta Geological Survey Map 572, Surficial Geology of the Chipewyan Lake Area (NTS 84A/NW).

Purpose:
For query and analysis of the surficial geology of the Chipewyan Lake area (NTS 84A/NW) in GIS format.

Data Quality Information:
Logical Consistency Report:
The digital vector data are discontiguous, topologically correct polygons as built and enforced using ArcGIS software. Due to the availability of high-quality, Light Detection and Ranging (LiDAR) bare-earth digital elevation model data (unpublished) for NTS 84A/NW, it was possible to delineate polygons and lines that would otherwise be unobservable. Adjacent map areas have not been mapped using LiDAR; therefore, new feature boundaries have been identified in NTS 84A/NW that do not have a corresponding boundary in the adjacent study areas. Consequently, NTS 84A/NW is not fully edge-matched with adjacent areas.
Completeness Report:
The data represent surficial geology interpretations based on LiDAR bare-earth data, orthorectified aerial photographs, and previously published mapping in the area.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
We estimate the accuracy of the surface-feature interpretations to be better than +/- 100 m on the ground, based on informed judgement of the effects of all combined map-production errors. No formal accuracy check verified the interpretation.
Lineage:
Process Step:
Process Description:

Our processes included

1. making a LiDAR imagery mosaic for complete coverage of NTS 84A/NW and relief shading the LiDAR bare-earth digital elevation model (DEM);

2. clipping Landsat-8 scene LC80440202013250LGN00 (courtesy of the U.S. Geological Survey) to the map area boundary;

3. performing image classification on the Landsat data, collecting training objects, and classifying peatlands using Landsat spectral properties and LiDAR topographic indices;

4. delineating non-peatland polygons from object-based analysis of a slope image derived from the LiDAR imagery

5. augmenting the classified landforms with digitization of polygons and line features across the LiDAR image of NTS 84A/NW using ArcGIS;

6. labelling spatial features;

7. checking the quality of the digital file; and

8. proofreading the text.
