Some of you may have heard of a relatively new thingy on Google maps called streetview. Basically someone has been paid to drive a van loaded with cameras around streets all over the world, and the resulting images have been digitised so that you can get a 3D view of the world from street level, as well as spy satellite.
How could this be useful you might ask? well, Today I've just been having a look at one of the roads beside Paekakariki railway station. i can see all the houses, and have a guess as to when they were built etc. I don't think it will make too much difference as I will probably just model a set of railway houses along this edge of the layout. I've also had a look at the outside of the Air-rail shed on SH 1, as well as the station buildings.
while I don't think that there is much demand for rural areas, the cities seem to be fairly well covered. Its worth a play just to see if you can find anything useful.
(Oh, and if you are not on what passes for broadband in this country, don't even bother)
