Description:
Abstract:

This GIS dataset depicts the surficial geology of the Whitemud Falls Area (NTS 74D/NE) (GIS data, line features). The data were created in geodatabase feature class format and output for public distribution in shapefile format.

These data comprise the line features of Alberta Geological Survey Map 620, Surficial Geology of the Whitemud Falls Area (NTS 74D/NE).

Purpose:
For query and analysis of the surficial geology of the Whitemud Falls Area (NTS 74D/NE), in GIS format.

Data Quality Information:
Attribute Accuracy:
Attribute Accuracy Report: n/a
Logical Consistency Report:
The digital vector data are line features built using the ArcGIS software. Due to the availability of high-quality, Light Detection and Ranging (LiDAR) bare-earth digital elevation model data (unpublished) for NTS 74D/NE, it was possible to delineate polygons, lines and points that would otherwise be unobservable. Adjacent map areas have not been mapped using LiDAR; therefore, new feature boundaries have been identified in NTS 74D/NE that do not have a corresponding boundary in the adjacent study areas. Consequently, NTS 74D/NE is not fully edge-matched with adjacent areas. Line features intersect only where intended. The digital vector data contain detailed features not shown on the map due to scale.
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:

Process Step:
Process Description:

Our processes included:

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

2. relief shading the LiDAR DEM;

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

4. performing machine learning on the Landsat and LiDAR data to classify peatlands based on their spectral properties and topographic characteristics;

5. delineating and digitizing non-peatland polygons and line features across the LiDAR image of NTS 84D/NE using ArcGIS 10.8;

6. labelling spatial features;

7. checking the quality of the digital file; and

8. proofreading the text.
