  • Main North Line [11J]: Addington 10

    As of now here is what has been drawn excluding Plant Zone and the workshops. Apart from adding those areas, generationalising all the track (checking to see how much still exists today) is another task to be completed. I have decided to draw all the yards from scratch (compared to the stuff I did in…

  • Main North Line [11I]: Addington 9

    I have now refactored and re-rendered all the geojpegs for Addington and have started working on the maps. Along the way some issues have been found with the masking on the composite mosaics requiring some further refactoring and re-rendering. However this isn’t serious enough to affect maps, it just affects the background when they are…

  • 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,…

  • 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…

  • Main North Line [11D]: Addington 4

    Welcome to our Facebook Group readers (NZRailMapz) as this will be the first entirely automated blog post sent to you, courtesy of IFTTT and the Buffer service. 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…

  • Main North Line [11B]: Addington 2

    The Addington mosaic has been a lot of fun. Working with so many large layers in one image is taxing on computer resources, and one relatively fast PC (its CPU is a Pentium G with 2 cores but no hyperthreading) with nothing else open and 16 GB of RAM is still quite slow working with…

  • Main North Line [11A]: Addington, etc

    Having completed sorting through aerial photos of the MNL and now having a complete set, the next task is to start doing stuff with the photos. The first thing that will happen is I will do a set of historical maps for Addington, as that is where the MNL starts. When I first started looking…
