The predictive surficial geology maps were subsequently generalized in order to conform to cartographic standards for a 1:250 000 map sheet. The generalization process included 4 iterations of a 3X3 pixel majority filter, conversion of the data from raster to vector format and removal of polygons less than 30 000 m2. Polygons below this minimum size threshold were replaced with the neighbouring classes using the expand tool in ArcGIS. Special treatment was given to predicted bedrock in regions and outcrops to maintain the spatial distribution of small discrete outcrops without overloading the map sheet with bedrock clusters. Predicted bedrock polygons smaller than 15 000 m2 were removed, and the ones between 15 000 and 30 000 m2 were converted to points using the centroid command in ArcGIS. The outline of the polygon were also smoothed by 150 m using the smooth line command in ArcGIS.
