So this is what is finalised for the fill styles.
These two of Addington show the styles for buildings and structures.
This one of the second Clyde station shows the site border styles which are dash-dot patterns. I am working on fixing up the aerial photos which turn out to be correct for 1977 (shown above) and just need some adjustment for the 1981 period, so that I can finish the maps for Clyde and move down the line to Alexandra. I don’t actually use sites all that much on maps as it is, and may well look at ditching them for smaller areas as the visual clutter from the extra lines is something I want to reduce, especially at smaller scales.
