I'll just check-in here. At the moment my brother and I are alternating two-week shifts as my mother needs full time care. There's no Internet here, so I'm stuck with mobile data
I have made some progress with the AFS2 version of Real New Zealand Christchurch, but I'm not sure when I can get back to this.
I have done experimental work on the Southern Alps, and the Coromandel Peninsula, using LINZ data - - including 5 metre elevation data where available. For my purposes, LINZ is the only real option, because of their generous licensing. A long time ago I supplied IPACS with the NZ elevation data, and they did the mesh conversion. Now, of course, we are able to do this ourselves.
I still need to do some work figuring put how to get the best out of the aerial images, so far I've just been using the same imagery I built for Prepar3d, but it loses something in the translation... X-plane normally just needs a gamma correction, but AFS2 is a bit trickier.
I'm not sure what early screenshot I've made available online, I'll have a look and post some links if I can.
Anyway, I would be keen to help with A NZ-wide project, although I'm not sure how much time I can give with things as they are.
I still have hopes of releasing a payware Christchurch, this is high on my list. However this could be the airport only if there was an existing base - so far this is a chicken and egg thing, releasing the Christchurch scenery with the same coverage as the Prepar3d version is not an ideal solution, with nothing but default everywhere else.
EDIT sorry about the autocorrect errors, I'm too old to type on a phone.
I forgot about Wellington, another area I've been working on, again with a 5 metre mesh.
