So this has been a lot of work but I now have usable aerial photos of Christchurch, Linwood and Opawa. As I noted previously I chose to extend the limit of the previously drawn maps from Wilsons Road out to the Opawa bridge. This means the total length covered is from just under 9 km, to 11.75 km - a total of nearly 4 km. All the tiles have been rendered (a total of 29, which is a lot considering how long it takes the computer to generate each one), but one needs the mask to be altered and then re-rendered, and I'm looking to add several more around the edges.
With all this work the Otago Central maps have had to wait except for one post about Galloway. Now that I have the Christchurch maps I will be working on them at the same time as carrying on with the Central and working up to the next station at Chatto Creek which shouldn't be a lot of work, and then further onward. In fact this section of the Central maps shouldn't take long to do.
Here is some of the Christchurch stuff that hasn't been published so far.
