NZ Rail Maps
Good afternoon. As detailed in the last blog post, the current activity being focused on is preparing a webmap preview of the Greater Christchurch area. A set of maps for this area in conjunction with the development of Christchurch Transport Blog and campaigning for the Christchurch commuter train proposals were put together last year but still need work to make them complete. For the webmap preview the focus is on completing them as quickly as possible, perhaps with some streamlining to speed things up a bit, so the additional research done up to the end of last year to identify the names of premises, for example, can be skipped for now.
So far, work has been done on Heathcote, Woolston, Linwood Loco and Waltham. This means that as of now, the yards from Lyttelton through to Addington are ready for the preview. The following remain to be completed:
As far as is known, aerial mosaics for all of these areas have been completed, so all that is needed is digitising (tracing the various features into the GIS) off the aerials.
A reasonable estimate of the completion to the level required for the webmaps proposal is therefore about another two to three days. This assumes no significant aerial mosaic correction is needed. To date only some of the mosaics for Heathcote have been corrected, although other errors are apparent here and there.
This preview will include all available aerial photography, which
in addition to historic mosaics, will also have Linz colour aerial
photography from 2011 to 2018, which has not been made available
in any of the other previews so far. The Project is not
guaranteeing this will be the level of aerial photography
available in the full site when developed; but this level will be
included in this preview.
