Sometimes good news crosses your desk - and here's good news ...

A story of success one year on:

A year ago we approached you for your tracks data to have it included in a national dataset of Walking and Biking Tracks.

You and the LGGA project team made this happen and a national tracks dataset has been available from the LINZ data service since October 2014.

It’s a significant achievement and the project team are really pleased to report on this.

It has been well used since it was made available:

3,405 views and
361 downloads by October 2015.

The dataset data is now an integral layer for wams.org.nz, giving their users the ability to nationally view and search within the mapping site. (See below a visualisation of where people have been using the data from WAMS)

We have also had reports of how useful it is to central government, other organisations and individuals. It is rewarding to hear that – you put in effort to get the data collated; then the project team worked very hard to pull it all together into a single dataset.

What next?

Now we are taking a deep breath and asking you for your data again. For some of you this will be an update. For some of you, this will your first time and we welcome getting your data.

We would like to have a push to get the data updated before the summer ready for all those folks who will be getting out and about. Last year there was a noticeable spike in usage in December.

Information to help you provide the data:
  • If you haven’t supplied data before, the best place to start is the User Guide and data templates. 
  • The project team have recently added a domain to describe spatial accuracy which can be downloaded in excel or this google sheet.
  • Also don’t forget each of your tracks should have a unique number

There are a few options for getting tracks data to LINZ:


If your data is already available in the standard via web download or web services (e.g. WFS) – please provide LINZ the details through to Customer Services (customersupport at linz.govt.nz) with the specific subject line “LGGA National Tracks by 11th December 2015 and they’ll help themselves. LINZ will inform you when they have picked up the data.


Map your tracks data into the tracks data model (based on the guide and data templates http://lgga-nz.blogspot.co.nz/p/tracks-project.html) and send it through to Customer Services (customersupport at linz.govt.nz) with the specific subject line “LGGA National Tracks” by 11th December 2015.


Simply extract your existing tracks data from your database (in a common geo data format, shape, geodatabase, kml, map info, etc) and send it through to Customer Services (customersupport at linz.govt.nz) with the specific subject line “LGGA National Tracks”. If you have a description/metadata and spec you use to manage this data, please send that through too by 11th December 2015.  LINZ will then process the information for you into the agreed data structure.


A secure FTP site has been setup at LINZ for you to upload your tracks data.  Please contact Brent Robertson brobertson at linz.govt.nz for the FTP login details

Once again the Local Government Geospatial Alliance (LGGA) and LINZ appreciate your assistance and are looking forward to having an updated national Walking and Biking Tracks dataset.

Statistical Standard for Geographic Areas (SSGA) consultation Phase 1

Dear GIS users and users of small area data

Statistics New Zealand are currently undertaking a major review of our statistical geographies and will shortly be seeking feedback on these geographies.

The review of the Statistical Standard for Geographic Areas (SSGA) will:
·       determine the optimal statistical geographies required for outputting Statistics NZ data
·       develop a set of statistical geographies for output purposes, and
·       define the geographic concepts, standards, boundaries, and maintenance strategies.

The SSGA review is being completed in two phases. In phase 1, we are reviewing small area output geographies (including area units), and the urban/rural classification. In phase 2, we'll look at other relevant geographies that will make our data more meaningful for you. These may include geographies relevant to a super-city, Maori, or even labour market areas. The standards and concepts for phase 1 geographies are being established in 2015 - 16 and boundaries will be set in 2016 -17. Phase 2 will commence in 2018.

Consultation for phase 1 of the Statistical Standard for Geographic Areas (SSGA) is now open.

An overview of the SSGA review, and consultation papers on small area output geographies and the urban/rural classification are available on our website - http://www.stats.govt.nz/methods/classifications-and-standards/current-classifications-and-standards-review/stat-std-geo-areas-2015-review.aspx.

We’d love to hear from you, so you can help us help you. Please send your feedback by 8am Monday 14 December 2015. You can either complete the consultation using the online form or join the discussion on Loomio. All details are available in the consultation papers.

As key users of our data, your feedback is important to help determine the optimal statistical geographies needed for producing data and we look forward to receiving your feedback.

Historic Imagery is here

Are you a history buff or interested in changes in land use over time?  Then you’ll be glad to hear that LINZ has made a handful of digitised images from the Crown historic aerial photo archive available for download from Flickr.

LINZ has published them to showcase this valuable content and trial ways of distributing images in the archive. Great progress has been made to date, with 20% of the archive now digitised.

Digitised Historic Aerial Surveys Available for Download (1936-2005) layer shows the extents of the digitised surveys published on Flickr.

NZ Aerial Photo Footprints (1936-2005) layer shows the extent of each photo within the archive. Due to the feature density of the dataset, we recommend you download a cropped area of data and view it in a GIS for easier analysis. The ‘scanned’ column tells you whether the photo has been scanned yet. See the article on WFS filtering below to download a file from this dataset of only the records that have been scanned.
