Source data: Pre-existing digital solid geology/tectonic interpretations existing only for portions of the State Selected polygons from 1:2000000 surface geology digital dataset Various hardcopy solid geology/tectonic interpretations at varying scales and detail The remainder of the interpretation is newly created for this dataset Processing steps: Geological linework in relevant areas imported from digital datasets, or scanned and rectified into desktop GIS Linework modified and extended on desktop GIS into uninterpreted areas using geological data and interpretations from drillholes, geophysical surveys and other published reports and maps Linework cleaned and coded Polygon topology built Polygons coded according to attribute table constructed as dataset assembled Geological attributes are based on interpretation of features in the subsurface which are not directly observable; thus they are subject to alternative interpretations. |
