Hi there
We are looking forward to working with you next Tuesday 2nd October,
on the Key Datasets for Resilience and Climate Change.
The workshop will run from 10am until 3pm, and the proposed agenda is set
out at the end of this email.
ACT
Please find attached an update improvement plan, which now includes all
datasets to be discussed.
Where to find us:
The workshop will be held in the LINZ offices at 155 The Terrace, Wellington.
UNDER
As you enter Radio New Zealand House on the ground floor, walk straight ahead to the “Argest”
doorway. Hoki is the third meeting room on the right.
Background:
LINZ has identified 12 key dataset groups which are important for Resilience & Climate Change,
INFORMATION
based on People, Property, Transport, Rivers and Topography.
The purpose of this workshop is to bring together data custodians from the public sector, with a
focus on People, Building, Address, Suburbs, Property and Aerial Photography.
RELEASED
For each of the key datasets, we propose starting with a five minute update from the data
custodian on current work plans.
We will then look at the feedback collated to date, to start our discussion on potential data
improvements – see attached
OFFICIAL
· Who is the appropriate data custodian?
· Are the suggested improvements valid and correct?
·
THE
Are users aware of the latest developments?
· What might be achievable from the suggested improvements?
· What are the barriers, if not?
· What needs to happen next?
We are pleased to have André Post, from Ministry for Primary Industries (MPI) attending, to
represent user requirements during our discussions.
Ultimately, our aim is to agree and implement an improvement plan for each dataset. However,
the aim of this workshop is to consider the user feedback received to date and agree our next
steps.
We look forward to seeing you next Tuesday .
Thanks, Susan

THE
Draft Improvement Plans for Key Datasets for Resilience & Climate Change
Background
LINZ has identified three key challenges where LINZ can make a significant contribution to the big
picture and support New Zealand Inc. The key challenges are water, urban areas and resilience and
climate change. The focus of this document is to support efforts to prepare for, mitigate and adapt to
the impacts on land and sea of climate change and one-off events.
LINZ has identified 12 key datasets groups which are important to support the work of resilience and
climate change:
People & Property:
Address, Building, Property, Population
ACT
Transport:
Road and Rail Network
Rivers:
River Network and Water Catchment Boundaries
Topography:
Elevation, Coastline, Aerial Photography and Topo Maps
Issues with these key datasets have been collated from the resilience community. LINZ facilitated a key
dataset workshop as part of the NZGIS4EM Special Interest Group in August 2018, and feedback has also
been sought via interviews with key users. This feedback has been used to prepare the draft data
improvement plans set out in this document.
UNDER
Key Data Workshops
It is proposed to run a series of workshops with the data custodians of these key datasets to share the
data issues raised and draft an improvement plan. These improvement plans wil then be shared with
key users for review and then confirmed with the data custodians.

Suggestons for general improvements
1. Make it easier to identify key datasets for resilience & climate change on data.govt.nz
2. Add geospatial dataset search to data.govt.nz
3. Set up functionality to enable the regular download and updates of key datasets for resilience for a
Council, for a wider region and for New Zealand to enable easy access to date if internet access were
not available.
4. Run workshops on key datasets so resilience community can make the most of the available data.
5. Offer call centre assistance, or live chat similar to the Stats NZ website, on key data issues and ACT
standards

People & Property: Address
Datasets
• NZ Street Address
Custodian
Land Information New Zealand (LINZ) –Addressing Team
Use Case
Risk – estimate how many people are within a tsunami evacuation zone
Readiness - which addresses are outside travel distance to a Civil Defence Centre
Response – which addresses need to be searched immediately after an event
Recovery - which addresses need to be demolished after a serious event
ACT
Climate Change - which addresses are susceptible to sea level rise, flooding,
inundation and tsunami
Data Issues
Good Practice
A national register of addresses is already established, including a known
maintenance programme, and established relationships with local authorities.
Data is available under Creative Commons licence
Source
Multiple data sources reported including LINZ, Councils, CoreLogic, Esri GeoCoder,
UNDER
which means there is no clear single source of truth for a national dataset.
Coverage
National coverage exists, but data quality, including currency, consistency and
completeness, is variable.
Attribution
There is no persistent, unique ID for an address
INFORMATION
Addresses are not associated with a building ID, to help a user identify a building
There is no useful attribute to enable a user to quickly filter the data for a region.
Limitations
Addresses are collected for different purposes, which creates limitations of use
during an emergency event.
RELEASED
LINZ Addressing datasets currently only includes addresses allocated by local
authorities. Local authorities do not collect addresses in a consistent way. For
example addresses may be captured for rating purposes only, but need to take
account of other addresses in use for example for library membership, dog
OFFICIAL
registration and shops.
Different response organisations referencing different address datasets. For
example Emergency Services use CoreLogic which includes unallocated addresses.
THE Addresses do not accurately represent individual buildings, for example a hospital
campus may have multiple buildings represented by a single address point.
Is the correct location of a farm address the farm house, the centre of the farm or
the entrance to the farm?
28 September 2018
Page 4 of 17
Colloquial names used in an emergency response are not included in the address
dataset, which makes it difficult to geocode data, especially in rural areas.
Accessibility
Data is not published as an Esri REST service on LINZ Data Service
Data is not discoverable as an OGC WFS service on data.govt.nz
Data is not discoverable as an Esri REST service from data.govt.nz
Maintenance
There is concern about the consistency between the local and national data.

Response – quickly identify the location of a person requiring emergency support
Recovery - which communities require additional funding for economic
regeneration after an event
ACT
Climate Change - which communities are susceptible to sea level rise, flooding,

Data Issues
Good Practice
Suburbs dataset is created and maintained based on a practical requirement to
respond to emergency events.
Names extend beyond addresses to include islands and bays, which provide more

Key Datasets for Resilience & Climate Change
People & Property Workshop - meeting notes
A few datasets MPI require under the key dataset groups are sourced from CoreLogic. A property
and a farm are not the same thing. Farm boundaries are very important for MPI regarding the
property group. See presentation for further details.
Questions:
Is community resilience a part of MPI’s function? Yes, MPI has a welfare function.
1. Dataset group: Aerial photography
Representative introduction: Andrew Ferrel - LINZ
In CHCH there was a need for imagery – LINZ disseminated this. LINZ started coordinating imagery
(with DoC and MPI for funding) and making it available openly; only 7% was available openly prior to
ACT
CHCH. Currently, LINZ makes sure that all organisations requiring it get it instantly for each update
i.e. Eagle, CoreLogic etc.
Discussion:
- We don’t want to be having to wait for a download during an event. We want data available
via download for preparedness in case we lose internet. MPI does have offline capability.

2. Dataset group: Property
THE
Representative introduction: Chris Kane - LINZ
LINZ aim is to make information visible relating to NZ property; LINZ has much of this data but it’s
not connected; all of the data needs to be linked together. Ideal y, we want anyone to be able to
understand and access this data; Individual representations of property to be as visible and useable
as possible – first aim

Key Datasets for Resilience & Climate Change
People & Property Workshop - meeting notes
- Datasets that are vital include address
- Property is defined as a sellable object
- LINZ currently developing a tool for agencies to use
- ~By the end of March 2019 80% of a good version of a state register will be complete
- A lot of the most valuable data is not in the District Valuation Role. The link to the VA is
made by QV or similar
- Rating unit is a proxy for the property
- Rating Valuation Act, and Local Government Rating Act 2007 (defines the rating information
that they need to put the property file together)
- DVR to be published for available areas in the next ~3 months. DVR wil tell you a little bit
about use
- LINZ to go back and forth with the councils, councils will be a main user
ACT
- Audit file is for property. A parcel may have a statutory action against it
Discussion:
- LINZ explorer tool to be released, potentially agencies to pull this information out via a API
- LINZ owns some datasets
- LINZ leading the IPS business case – high cost benefit; councils, QV and CoreLogic – cost is
engagement

3. Dataset group: Suburbs
Representative introduction: Matt Donaldson - FENZ
THE
No plans for the NZ Localities dataset yet. This was developed from a need for suburbs. All localities
of NZ covered: lakes, rivers etc. included. This helped to remove ambiguity from (address) streets as
cities/ towns are not used in identification. Still have the same data licence agreement from 2005.
FENZ have no money to develop this dataset. Dataset is fairly fit-for purpose but there are not
official specifications or requirements for it. Matt is trying to get some funding to develop this and
its requirements, ideally make it open via CC. Not appreciated internally, appreciated externally.

FENZ needs to get their CE on board with this. At the moment we’re only adjusting boundaries when
feedback is given. A lot of feedback is given by NZ Post.
- Localities help identify a 111 call
- Available outside of FENZ by request
Discussion:
Suburbs and localities – completely different. A suburbs dataset doesn’t exist; LINZ maybe to
develop a suburbs dataset?
- Localities help identify a 111 call
Actions:

Census response rates are lower now than in the past. Information mainly released in area units.
Statistical Area 2 is the equivalent of old boundaries. Stats feel they have an obligation to deliver

more detail (meshblock level) since being in today’s meeting, i.e. populations at meshblock by age
range. Geographic updates occur annual y but migration, deaths etc. make this difficult. Migrants
linked to address. Some work is happening on national migration, to be reported on at national level.
Population estimates during an event was very challenging, CHCH example; this is now easier with

5. Dataset group: Address
Representative introduction: Ben Jones and Tania Janssen - LINZ
67 TA’s have to provide updates to LINZ – LINZ relies on this. Frequency, quality and format varies.
Addressing team puts this detail into AIMS. Addressing standards are set by the surveyor general.
Addresses come in and are reviewed against AIMS and are published once complete. This is just a
ACT
subset of al of the addresses being used.
There is a project being set up to understand al other addresses, LINZ potential y to understand
these and create a dataset for NZ fit for all purposes. Different parts of the same council may use
different addresses.
The purpose is to have the end product useable by everyone and understood by everyone.

Discussion:
Stats NZ has an up to date register of the address – LINZ to use to help verify address.
- TA’s provide address updates
- Governor General as the delegation authority

Key Datasets for Resilience & Climate Change
People & Property Workshop - meeting notes
Building outlines created from the capture of a roof via aerial imagery; they are not footprints. A
number of use cases have come out around this. National coverage is being completed at this time.
Realistically we’ll have 95% population coverage of NZ’s area; 98% coverage of NZ’s populated areas
by July 2019. Not a pilot dataset anymore. New layer will have: persistent building I.D’s, outline will
be associated with the imagery, name, use, suburb, town/ city, TA, capture method, capture source,
external source I.D, and lifespan. Not all information will be disseminated to avoid user confusion
but wil be open and available by request. Resolution: 10m2 and above. Main use case is topographic
product.
Discussion:
- Data dictionary specifies what the building has been defined as
- Building outlines are to have on-going maintenance
ACT
- Earthquakes building prone register (criticality)
Actions:
- Associate building with an address – IPS API (in progress) - consensus
- Make available as an Esri REST service - suggestion
- Look at FENZ building data/ names – FENZ and LINZ

Issues:
- No height estimation
- No information on number of story’s within a building
- Criticality not an attribute

Lessons learned from today’s session:
- Already many improvements happening in similar areas to what is being suggested for each of the

dataset groups
- Interesting to get an idea on the scope of work being done
- Stats NZ understanding how we can and/ or could be able to be better ready to respond

- REST services to be looked at as being delivered through the Koordinates platform; seems like a
uniform requirement
- Resilience is a good way to get different organisations talking and engaged

- No one size fits all can be assigned to everyone
- We can't do evidence based decision making without location and statistical information being
integrated
- Great to be able to discuss these topics freely in a safe environment
