This is the first issue for 2018 and there have been a lot of exciting projects going on at LINZ to bring you more data, with many more to come. Top of the list is our brand new 10m cloudless satellite imagery dataset for the NZ mainland. There is also news on historic imagery and elevation
We can’t put everything in this update so follow us on Twitter for more news from LDS. Are you using our data and think we should be following you? Use the @LINZLDS handle and let us know!
A satellite view of New Zealand
We’re excited to bring you another new imagery dataset. The NZ 10m Satellite Imagery (2017) dataset is a satellite imagery mosaic for the whole of New Zealand at a resolution of 10 metres, and was captured between December 2016 and December 2017 by the European Space Agency Sentinel-2 satellites.
This data will be refreshed once a year during the 2-year pilot, making it the most frequently updated of our imagery datasets. It also makes it perfect for use across environmental monitoring, natural resource management, land use land monitoring, and disaster preparedness.
We’ve seen our customers create great products and services to map and monitor New Zealand using the imagery data we make available through LDS – aerial and historic imagery, and elevation. Satellite imagery will complement these existing datasets, enabling you to deliver even more and better innovations to help us all understand the world, our environment and plan for the future.
We’re making the data available to you on a pilot basis to help us assess the value of ongoing release of satellite imagery. So help us make our case by downloading and using this data and giving us your feedback (see the satellite imagery dataset on LDS for the link to the survey).
Onwards and upwards for elevation data
Yes, more LiDAR data will be coming soon. Over the next few months we will be adding new datasets for Auckland, Canterbury, Nelson, Tasman, Marlborough, Waikato, and Palmerston North for a significant increase in national LiDAR coverage.
Data capture has also just begun for the ambitious all-of-Northland LiDAR project, with data availability projected for 2019.
Preserving the past one image at a time
Did you know you can download copies of scanned Crown-owned historic imagery from Retrolens? This fantastic service, brought to you by the Local Government Geospatial Alliance, allows you to search by address for images of scanned historic aerial photos and surveys from partner regions. Use the dataset of survey footprints of historic aerial photos flown for the Crown and the related Crown photo footprint dataset on LDS to identify specific images of interest, or to order images not available via Retrolens.
NZAM archive index also available
We’ve also published another historic imagery index on the LDS. With the Historic Aerial Photos, Survey Footprints, NZAM (1939 – 2008) dataset you’ll be able to identify the coverage of aerial photography for mainland New Zealand flown by New Zealand Aerial Mapping (NZAM) for private contract work between 1939 and 2008. Scanned images from this dataset are only available for order from Opus.
Searching for NZ place names made easier
The New Zealand Geographic Board Ngā Pou Taunaha o Aotearoa (NZGB) has just released a new version of the online New Zealand Gazetteer of Place Names. The updated Gazetteer has improved search and filtering functionality, and better basemaps to enhance the overall user experience.
The NZGB is also working on a number of improvements to place names data that you’ll see in the LDS:
- Targeted capture of missing recorded and collected names from historic maps
- Improving positions of 3000+ recorded names in the Otago Region
- Improving positions, descriptions and other errors for names in Antarctica

‘Feature walling’ topographic data
How else can you use geospatial data? A customer, with a love for the visualisation of our landscape, got decorative when they downloaded LINZ topographic maps, joined them together to form a seamless extent and had them commercially printed on to self-adhesive wallpaper. Walking down their hallway they can now enjoy the splendour of the Southern Alps / Kā Tiritiri o te Moana.
