This GIS dataset depicts the surficial geology of the Hamburg Area (NTS 84E/SW) (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 565, Surficial Geology of the Hamburg Area (NTS 84E/SW).
Our processes included
1. making a mosaic and relief shading the LiDAR for complete coverage of NTS 84E/SW;
2. clipping Landsat ETM+ scene 048020100990804 (see map 565 for full reference) 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 Iight Detection and Ranging (LiDAR) topographic indices;
4. digitizing non-peatland polygons and line features across the LiDAR image of NTS 84E/SW using ArcGIS;
5. labelling spatial features;
6. checking the quality of the digital file; and
7. proofreading the text.
