So back to Volume 12, this time back to working on the Otago Central again. Having done the maps last month for the first Clyde station, now I have to get to work again on the 2nd station. The mosaic has turned out to have an issue with the section particularly relating to 1977, that…

1st Clyde station in 1972.

Last time I was talking about the challenge of aerial maps of the north part of Lake Dunstan. All of Lake Dunstan is of interest for historical purposes due to the hydro development resulting in indundation of a considerable area of land. Just as an aside I am about to do a map of Lake…

So I have been working on two mosaics in particular, the ones of Lake Dunstan from Cromwell to Luggate, and the ones of Clyde, over the past week but not as much as the previous week but that is what happens with ebb and flow of different time commitments etc. The Lake Dunstan ones are…

Not the railway, but this is what I have been working on for the Clutha valley north of Cromwell. The area on the left is called Lowburn and on the right is Northburn. The Lowburn bridge was built in the mid 1930s and replaced a punt. The old NZMS1 map of the Clutha valley from…

In the past few days I have been doing newer higher resolution aerial mosaics for Clyde. Here are screen dumps of what has been completed so far. Clyde in the 1960s.    Clyde in the 1970s.  Clyde in 2015. The main work still to be done is for 1978-1991 which includes the following changes: 1978:…

So the Cromwell maps took a little longer because I had to make bridge tiles to bridge the gap between the new aerial imagery and the old stuff I have for the rest of the gorge. So that there is a fairly seamless join between the new tiles and the existing ones. The bridge tiles…

As mentioned yesterday I am now working on new maps of Cromwell and hope to get some coverage that will also give me the valley going to the top of Lake Dunstan in conjunction with the Cromwell Museum to have full coverage of the historical appearance of that area.  After some experimentation I am doing…

Yesterday I wrote about getting new aerial coverage for the stations in the Ida Valley (Auripo, Ida Valley and Oturehua). It has only taken a little bit of time to create or update mosaics for the first two and Oturehua will follow shortly. Once that is completed the maps for all three locations can be…

Having been looking at aerial photography in various areas around the Otago Central today, I have discovered the official NZR surveys for both Cromwell and Clyde, which date from 1972. As this is of much higher quality than the 1960s aerials that I previously used for the maps of these stations, I expect to cascade…
