Description:
Abstract:

This GIS dataset depicts the surficial geology of the Gregoire Lake area (NTS 74D/SW) (GIS data, polygon features). The data were created in geodatabase feature class format and output for public distribution in shapefile format.

These data comprise the polygon features of Alberta Geological Survey Map 645, Surficial Geology of the Gregoire Lake Area (NTS 74D/SW).

Purpose:
For query and analysis of the surficial geology of the Gregoire Lake area (NTS 74D/SW), in GIS format.

Data Quality Information:
Attribute Accuracy:
Attribute Accuracy Report: n/a
Logical Consistency Report:
The digital vector data are contiguous, topologically correct polygons as built and enforced using the ArcMap 10.8 software. Due to the availability of high-quality, light detection and ranging (LiDAR) bare-earth digital elevation model data (unpublished) for NTS 74D/SW, it was possible to delineate polygons, lines and points that would otherwise be unobservable. Not all adjacent map areas have been mapped using LiDAR; therefore, new feature boundaries have been identified in NTS 74D/SW that do not have a corresponding boundary in all of the adjacent map areas. Consequently, NTS 74D/SW is not fully edge-matched with all adjacent areas.
Completeness Report:
The data represent surficial geology interpretations based on LiDAR bare-earth data, satellite imagery, 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.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report: n/a
Lineage:
Process Step:
Process Description:

Our processes included:

1. making a LiDAR imagery mosaic for NTS 74D/SW;

2. relief shading the LiDAR digital elevation model (DEM);

3. making a Landsat-8 best pixel composite for the region using multiple Landsat-8 scenes from 2017–2019;

4. importing the Boreal Wetland probability dataset, which classifies peatlands according to their spectral properties and topographic characteristics using a machine learning framework in R statistical software based on a DEM, optical satellite data (Sentinel-2), and synthetic aperture radar data (SAR; Sentinel-1);

5. delineating and digitizing non-peatland polygons and line features across the LiDAR image of NTS 74D/SW using ArcMap 10.8;

6. labelling spatial features;

7. checking the quality of the digital file; and

8. proofreading the text.
