Strategic Plan 2015 - Objective 3 - Improve resilience to natural events

Enabling those who are making decisions on the impacts and risks of natural hazards to have the right information that will help protect New Zealanders and their assets

LINZ is well placed to contribute to datasets and information that enable better understanding of natural hazard risks and impacts. Better quality and more consistent data at a national level can be aggregated to support evidence-based investment and risk response decisions around natural hazards. Initially we will focus on providing information that will enable better determination of the impacts from flooding risk.

We are BEST placed to do this because:

  • We have core specialist geospatial capabilities (mapping, geodesy, topography, hydrography, and elevation) that can contribute to improving natural hazard data and information.
  • We have focused on flooding initially as it is the most common natural hazard event in New Zealand, with significant cost and impact on people and their assets. Globally the cost of natural disasters is rising year on year.
  • A key priority for governments is to create resilient communities that are able to quickly recovery from disasters.

We are seeking to accomplish:

Improved support for decision-making to identify natural hazard risk in New Zealand; better quality and consistency of data that can be aggregated at a national level to support evidence based investment; and better understanding of flooding and the impacts and risks of river flooding.

What we will achieve - better information and tools to assess the risks and impacts of natural hazards.

New Zealand will have better information and tools to assess the risks and impacts of natural hazards.

How we will do this

  • We will focus efforts on improving and making available information and tools both we and others provide to help understand natural hazard risks and impacts.

Success will mean

  • Information and tools will support decision-makers to make better decisions about the risks and impacts of natural hazards
  • Resilient communities have information and tools to be able to more quickly recover from disasters.

What we will achieve -  policy settings to assess the impacts of flooding on property and land

The policy settings will be in place to enable New Zealand to assess the impacts of flooding on property and land.

How we will do this

  • We will drive LINZ-related legislative change.
  • We will support other agencies to progress related legislative change.

Success will mean

  • Our property rights and land transfer legislation will operate efficiently and effectively in the event of natural disaster.
  • Information to identify resources, risks and rights relating to land is captured on property information accessible by landowners. (For example flood areas; building restrictions and/or consent notices.)

What we will achieve -  the spatial information, analytical models and visualisation tools needed to robustly assess and respond to flooding from rivers.

By 2020, stakeholders will have the spatial information, analytical models and visualisation tools needed to robustly assess and respond to flooding from rivers.

How we will do this

  • We will support lead agencies and stakeholders to progress and implement priorities for the flooding information system.
  • We will support new systems to manage the flooding information system.
  • We will support training for ongoing collection, management and use of information and technologies related to flooding from rivers.
  • We will take part in information infrastructure forums relating to flooding from rivers.

Success will mean

  • A robust flooding information system is fully operable.
  • People have the tools and capability to use the flooding information system.
  • The cost and impact of flooding on people and their assets is reduced.

What we will achieve -  Provision of datasets to enable the assessment and response to flooding from rivers.

We will provide the critical positioning, property and elevation datasets to enable the assessment and response to flooding from rivers.

How we will do this

  • We will leverage the activities, outputs and methods of strategic objective 1.
  • We will develop and implement an Integrated Vertical Datum across the land and sea.
  • We will coordinate the capture of public sector topographic LIDAR data which will contribute to the development of a national Digital Elevation Model.
  • We will develop a 1m Digital Elevation Model for river flood prone areas.
  • We will contribute to the capture of and contribute to the development of a database of building footprints with unique identifiers which will be complete in river flood prone areas.
  • We will improve the accuracy of river mapping in our topographical database.

Success will mean

  • Our data is being used to mitigate the impacts of natural hazards by those making decisions on the risks of natural hazards.
  • People can more easily understand, anticipate and plan for the potential impacts of natural events.
  • More informed decisions can be made on the location and protection of new and existing assets.
  • Better quality and more consistent data at a national level can be aggregated to support evidence-based investment and risk response decisions around natural hazards.
