As I wrote in my last post I am currently updating the map of Lauder station. 

These two images are respectively 1938 and 1965 images of Lauder. There is no apparent change in the layout of Lauder between these two periods.

At this stage there are no plans to extend the masking as I am unaware of any additional area that would benefit from being displayed in a part tile export.

The main improvement in this map will be the sharper 1965 aerial imagery due to having reduced the number of transform steps to the historical layer to one.
