Key Datasets for Resilience and Climate Change
Data Improvements
Quarterly Progress Update: September 2019
Introduction
LINZ understands the vital importance of having reliable, accessible information
to inform those working in emergency management and climate change. This is
why LINZ is investing in working with other lead agencies to improve the key
datasets.
A key dataset improvement plan was approved in June 2019. Quarterly updates
will be shared with the NZGIS4EM Committee as our customer representative
and with Ministry of Civil Defence and Emergency Management to inform its
related work on Essential Elements of Information. Next update due January
2019.
Data Improvement Highlights: Quarter 1
• NIWA updated the Rivers and Catchments data and released the data
under Creative Commons license CC-BY 4.0

key dataset improvement project.
Priority Improvements Update: Quarter 1
Key datasets to support those working in resilience and climate change have been
identified and their fitness for purpose assessed. Consultation with the user community,
and collaboration with the key dataset lead agencies, identified the following data
improvements which can be progressed over the next 12 months.
Below is an update on progress during Quarter 1 (June to September 2019) and planned
milestones for Quarter 2 (October – December 2019).
Lead agency is on track to deliver priority improvement to agreed timeframe
Lead agency has delivered data improvements to the public this quarter.
Lead agency is obtaining organisational buy in to deliver priority improvement.
1.
LINZ to provide a more comprehensive national coverage of
addresses by June 2021.
Q1 Gained agreement from some Territorial Authorities for LINZ to
access complete address datasets, rather than just recent
changes, and recently gained short term access to an address
validation tool for address analysis.
Q2 Understand the validation process, with the intention of having
RELEASED
some sample additional addresses to assess for quality and
validity. Plan for stakeholder engagements in the new year.
2.
LINZ to work with all regions to coordinate the acquisition and release
of
LiDAR data into open national datasets by June 2023.
Q1 LINZ has issued a Request for Tender to procure LiDAR capture
services on behalf of the 8 Regional Councils. Submissions due 4
September 2019. LiDAR for Marlborough and Manawatu-
Whanganui has been released.
Q2 Evaluate tenders and identify preferred supplier. Release
additional data to continue to build national height dataset and
publish blog on converting LiDAR data to NZVD2016 datum.

3.
NZTA understands the importance of providing easy access to
road
closure data, but currently is unable to commit to an improvement
plan.
Q1 Road closure network has not progressed due to recent
restructure at NZTA.
PROACTIVELY
Q2 NZTA to create high level understanding of the work required to
develop a road closure network of state highways and local roads.
This improvement is also being discussed with Ministry of Civil
Defence and Emergency Management.
4.
Stats NZ understands the importance of providing
small geography
population count information for use in responding to emergency
events and will explore options with LINZ on how best this could be
achieved.
Q1 First release of 2018 Census data is now available at SA2 level
(area unit replacement) attributed with population count, age sex
and ethnicity, and also available as Esri REST services.
StatsNZ Website:
https://www.stats.govt.nz/information-
releases/2018-census-population-and-dwelling-counts-nz-stat-tables
Esri REST services:
https://s3-stats.cloud.eaglegis.co.nz/arcgis/rest/services/Census2018
Datafinder:
https://datafinder.stats.govt.nz/data/category/census/2018/?page=3
Q2 Publish SA1 (meshblock replacement) dataset with population
counts and a variety of attributes. Provide further information to
Senior Managers about small geography population counts.
5.
LINZ
to improve access to
parcel attribution by June 2020 and
investigate the feasibility of creating a property boundary layer by
June 2021.
Q1 Publishing the parcel data as an Esri REST service is the first step
towards improving access to the attribution. Project Brief for
RELEASED
publishing key datasets as Esri REST services has been approved.
Q2 Publish Parcels as an Esri REST service. Opening up the District
Valuation Role is the key to generate a property boundary. Aim
to provide restricted access to some individual Council District
Valuation Roll data for testing. Release the Property Data
Management Framework for expert review.
6.
LINZ
to complete national coverage of
building outlines by June 2020.
Q1 Taranaki buildings published in September. Buildings in Bay of
Plenty, Gisborne and Marlborough have been captured and are
currently being verified.
Q2 Aim to publish buildings for Marlborough (already completed Q2),
Bay of Plenty, Gisborne and investigate capturing buildings in
areas where there is no aerial imagery e.g. Southland.
7.
Fire and Emergency New Zealand understands the importance of the
suburbs dataset and is working with LINZ to establish options
regarding the dataset by December 2019.
PROACTIVELY
Q1 Fire and Emergency and LINZ shared the key dataset initiative
with the Fire and Emergency Communication Centres
environment manager. High level options were discussed
alongside Emergency Services sector requirements. There are
concerns about the amount of work required when resources have
to remain focused on organisational priorities.
Q2 Fire and Emergency legal team will be engaged to provide an
opinion on the implications of Creative Commons licensing in light
of Emergency Services sector requirements for the dataset.
8.
LINZ to create a national
topographic basemap by June 2022.
Q1 High level design and business case approved for basemaps
project. Beginning with aerial imagery basemap. Topo basemap
has been reprioritised and will be second basemap to be built.
Q2 Aiming to develop aerial imagery basemap and test inhouse by
February 2020. Update website to provide information about
Topo50 and Topo250 update schedule and link to update history.
9.
LINZ to establish a process for coordinating the capture and delivery
of
imagery and LiDAR during an event by June 2020.
Q1 LINZ has developed internal processes to establish roles and
responsibilities during an emergency response to coordinate data
capture. Discussions with flying companies during LiDAR tender
helps understand capacity. Learnt more about Geospatial
Intelligence Centre offering
https://geointel.org
Q2 LINZ to run staff exercise to test the emergency response
processes. Draft specification for aerial imagery capture during
an emergency response to ensure timely data delivery. Plan user
requirements workshop for March 2020. Publish new imagery.
