Selwyn Street, Christchurch.

Main North Line [11G]: Addington 7
This is just a quick progress update. The refactoring is progressing well but the week is busy (week before Easter) with other things so not much is going to be done over the next few days. As my goal is to have all three pieces of Addington completed before doing any maps, it could be…

Main North Line [11F]: Addington 6; Otago Central Railway [62B]: Km Pegs 2
So Addington is being more or less recreated from scratch. Doing the adjustment in the middle part (Addington North as it is called in my computer) covering the Main North Line going north to Riccarton was actually relatively quick and easy to fix, as with all the linked layers, moving one moved all the others,…

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…

Main North Line [11E]: Addington 5
Well, Friday has been a whole lot more mucking around to make various adjustments to all of the Addington stuff, mainly in the area of adjusting the masking for the partial images. This has resulted in needing to re-render all the partial map tiles which is a relatively slow process. Hence the maps have not…

Main North Line [11F]: Addington 6
Today’s not-news is of yet another hold up in mapping. Because I made the stupendous discovery that some of the tracks aren’t lined up between the old and new aerial images. Unfortunately the nature of historical aerial imagery means that this is a risk. It’s my regret that the process I used did not pick…

I enjoyed writing these articles and sought in the process of this to provide…

I already use IFTTT to syndicate my posts on the NZRM Facebook page, but now they are expected to automagically feed to the group as well. Latest progress…

Main North Line [11C]: Addington 3
So as of last night I have finished laying out the Addington North mosaics in Gimp. Today’s job is to mask off the relevant bits of the retro images, and then render the part and full images for Qgis. Whilst I have enough now to start mapping Addington, I have determined to do only two…

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…
