Otago Central Railway [62A]: Kilometre Posts on the Rail Trail
The Otago Central Railway maps incorporate full mile post indications for the entire length. The positions have been derived from various information in the chainage books for the line and by estimation these positions could have an error of plus or minus 100 metres. Recently I have obtained additional information from Geoff Mackley that has…

Otago Central Railway [61C]: Finishing Maps – Cromwell-Alexandra 1
Well I decided that I needed to check everything starting from Cromwell so that is where I have been busy for the last few days. As it happens I had two sets of aerial photo mosaics from Cromwell, and they didn’t match up, so I re-rendered both the full and part sets of retro images…

Otago Central Railway [61B]: Finishing Maps – Clyde 1
So while I am working on the Addington mosaic, that is a pretty slow process with a lot of downtime waiting for Gimp to resize images, the best part is with another computer doing only that and nothing else, I can carry on with maps on my main computer. And in actuality that is a…

Main North Line [10]: Aerial Photography
Most of the mapwork over the past few days has been with MNL aerial photography which has to be downloaded and then sorted through to pick up just the photos I want. This is a slow process because of the download limit of 3.5 GB per download from the Linz website and the number of…

Otago Central Railway [60B]: Wingatui to Ranfurly 2
Well it has been a few days since the last posting, however as of today I am commencing to write Part 3. Part 2 came out last week in the Observer and my chief regret is that the maps weren’t actually completed for Part 2. This only needed Auripo map to be finished before the…
