How does KiwImage fit into New Zealand’s new Geospatial Strategy?
Land Information New Zealand(LINZ) have confirmed that this purchase is fully consistent with the aims and objectives of the new Geospatial Strategy. It provides common baseline data for all of government use.
Can I get sample imagery to evaluate?
Yes. A full set of products (pansharpened natural colour, panchromatic and multispectral) covering the two NZTopo50 Dunedin and Mosgiel map sheets will be available for evaluation by contacting the KiwImage Administrator. Sample imagery will only be provided to agencies that are eligible to join the KiwImage project.
Who has signed the KiwImage MOU?

Can agencies still join the KiwImage project?
Yes. You can join at any time of the project. The project started in 2007/08 and is programmed to run for 5 years until 2012. The fee structure is based so that any agency joining after year 1, will pay the same total amount as if they had joined in year 1.
Contact the KiwImage Administrator for current pricing information.
What are the product specifications?
There are 3 KiwImage products available.
- Product 1 – Bundled product (panchromatic & multispectral)
- Product 2 – Pansharpened product (natural colour mosaic)
- Product 3 – Basic product (uncorrected imagery)
Product 1 – Multi-spectral & Panchromatic The 2.4m Multi-spectral and 0.6m Panchromatic Bundle Product will be delivered as strips of ortho-rectified 16-bit imagery (block-adjusted) as opposed to a mosaiced product. This delivery method will maintain the integrity of the pixel values for the image analyst end-users. The image strips will be delivered per date of acquisition in a tiled and uncompressed format.

How much cloud & snow cover will there be?
Cloud
Initial delivery can be up to 10% cloud (subject to the criteria below), but then redelivered over time as cloud free.
- Initial delivery - 0% cloud free areas to be defined i.e. CBD's - major installations (oil or NZDF exercise areas).
- 1% cloud – Industrial areas of urban imagery. Cloud free final product
- 10% cloud – Rest of country. Cloud free final product In excess of
- 10%, but less than 20% - by negotiation. – Cloud fee by end of contract
- Cloud over water is acceptable
Snow
New Zealand - 1 Jan to 30 April capture in permanent snow areas – no fresh snow
Smoke
Images to be smoke free - For the avoidance of doubt geothermal steam is not considered to be smoke
In the first year there will be no imagery before 2005 in high interest areas and after first year no imagery older than 18 months at date of delivery to be added.
Landcare Research has kindly supplied their enhanced LINZ DEM for this project. This has been merged with the SRTM 1 Arc-second (30 m) product (http://www2.jpl.nasa.gov/srtm). The merged DEM will be used for the remainder of the project or until a better national DEM becomes available.
What ground control is being used?
For New Zealand LINZ geodetic control is being used, this is supplemented with cadastral control and control from other agencies. Normally LINZ’s 2 metre beacons are visible in the imagery. These should provide sufficient coverage for populated areas of New Zealand. It is intended that all ground control used will be maintained in a database and available for partners to use. This will include an image of each point and all reference and name information.
All inland water will be provided as imagery. Water more than one kilometre offshore will be filled black.
Will the pansharpened 8 bit product be mosaiced?
Yes, all 8 bit products will be mosaiced to NZTopo50 sheet boundaries.
Will the pansharpened 8 bit product be tiled?
Yes, all 8 bit products will be mosaiced & tiled to the following sizes:
| File Type | Tile size | Notes |
|---|---|---|
| ECW | 24km x 36km | Full NZTopo50 sheet |
| GeoTiff | 3km x 3km | 12 rows & 8 columns, 75mb |
| JPG2000 | 24km x 36km | Full NZTopo50 sheet |
How will I know the age of the image I am looking at?
Shape files will be supplied which shows the boundary of the Quickbird image scenes used to make up the mosaic.
The approximate dimensions of a single QuickBird image or scene are:
| Scene | PanChromatic | Multispectral |
|---|---|---|
| Pixels | 27,552 x 27,424 pixels | 6,888 x 6,856 pixels |
| Coverage | 272 km² | 272 km² |
| Size km | 16.5 km x 16.5km | 16.5 km x 16.5km |
The membership fees are paid annually to the NZDF, and is based on a tier level structure. For all the price options contact the KiwImage Administrator to get a copy of the KiwImage MOU which has a full breakdown of costs and all other relevant information.
Can I purchase additional QuickBird products specific to my needs though this project?
Normally yes. The project has the ability to purchase additional areas or re-fly areas previously captured. You will need to contact the KiwImage Administrator to discuss your needs.
What is the total storage requirement?
Based on the imagery received so far, the estimate for product 1 (Bundle Panchromatic & Multispectral) & Product 2 (Pansharpened), will be 12 terabytes.
Will KiwImage be hosting the data?
The initial scope of the KiwImage Governance Board was to host the imagery on a web server using the State Services Commission GSN. However after a tender process of solutions for the web service it was decided to focus on the purchase of imagery, and we will look at a web service in the future if the funding is available.
No you can not on sell or pass on the digital data. Data may be exchanged between agencies that have signed the MOU. For a list of agencies that have signed the KiwImage MOU click here.
Can I use the data to make products which I then on-sell?
You may print images or provide derivative products from the data and sell these at any size or shape, you are required to place an appropriate copyright notice with each image as stated in the EULA of the MOU.
Can I use the data as a backdrop on our public web site at full resolution?
You may make available to the public one screen view of the data at time at full resolution. They may download a single screen grab (at full screen resolution). You are required to place an appropriate copyright notice with each image as stated in the EULA of the MOU.
Tier 1 members set the priority sheets for the project. Currently the priority is to cover Northland, Taranaki, Hawkes Bay-Gisborne, Rotorua-Taupo, Wairarapa, West Coast, & Canterbury. Check the status maps to see if your area of interest is covered.
Not easily. We pay for deliveries as we receive them, this means that for New Zealand, we can only purchase imagery to the limit of the budget from the revenue of the project members. If additional funds were made available up front the rate of delivery could be increased.
Will DigitalGlobe’s WorldView 1 & WorldView 2 satellites be available to the project?
Yes. The WorldView 1 is currently operating. The satellite will only collect 0.5 m GSD panchromatic imagery, there is no multi-spectral capability. Because of this, its role restricted to emergency tasking such as response to disasters. The WorldView II was launched late in 2009. It is the planned replacement for the current QuickBird 2 satellite. Worldview II imagery is now being used as part of the KiwImage project.
Who makes up the KiwImage Governance Board?
The governance group consists of representatives from NZ Defence Force, Local Government, Land Information New Zealand and the New Zealand Fire Service.
Who will be the Custodian of the data?
The New Zealand Defence Force is the custodian of the data. They are already a large user of DigitalGlobe imagery and are a logical choice to host and quality assure the data.
Who do I contact for further information?
The KiwImage Administrator will be able to help you with further information regarding the KiwImage project.
