This GIS dataset depicts the surficial geology of the Wabasca area (NTS 84A/SW). The data were created in geodatabase format and output for public distribution in shapefile format.
These data comprise the point features of Alberta Geological Survey Map 561, Surficial Geology of the Wabasca Area (NTS 84A/SW).
Our processes included
1. making a mosaic and relief shading the LiDAR for complete coverage of NTS 84A/SW;
2. clipping Landsat ETM+ scenes 043020_0101_001006 and 043021_0100_001006 to the map area boundary;
3. performing object-based analysis on the Landsat data using the Orfeo Toolbox remote-sensing software, collecting training objects, and classifying peatlands using Landsat spectral properties and LiDAR topographic indices;
4. digitizing non-peatland polygons and line features across the LiDAR image of NTS 84A/SW using ArcGIS;
5. labelling spatial features;
6. checking the quality of the digital file; and
7. proofreading the text.
