This GIS dataset depicts the surficial geology of the Falher Area (NTS 83N/NW) (point features). 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 556, Surficial Geology of the Falher Area (NTS 83N/NW).
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.
