This GIS dataset depicts the surficial geology of the Yates River area (NTS 84N/NE) (polygon features). The data are created in geodatabase format and output for public distribution in shapefile format.
These data comprise the polygon features of Alberta Geological Survey Map 552, Surficial Geology of the Yates River Area (NTS 84N/NE).
Our processes included
1. interpreting the airphoto;
2. scanning each 1:60 000 airphoto as a gray-scale, 1200 dpi TIFF;
3. georeferencing images using 1:20 000 scale provincial digital base data (i.e., hydrography and roads) for control;
4. digitizing line features from each image individually and reconciling edge discrepancies;
5. labelling spatial features;
6. checking quality of digital file; and
7. proofreading text.
