Having moved on to Alexandra, here is a screenshot with the 1983 aerial displayed.
The aerials for Alexandra done so far do not need major work done. All that is needed is to adjust the masks to show the oil company sidings and Vacuum Oil on the historic imagery.
The other thing is to try to find if there are any new higher quality aerials of the area where Fulton Hogan's site is, further north on Dunstan Road. The diagram of the siding was done using a fairly low quality aerial and a plan from Archives NZ. I can't release the plan on the same license as the rest of the maps without ANZ consent, so I may just use that low quality aerial if there is nothing better in Retrolens as of now.
