LINZ has an active role in co-ordinating and promoting the use of geographic data to support New Zealand to prepare for and respond to emergency events and climate change.

After the 2016 Kaikoura Earthquake, LINZ was tasked to coordinate the data requirements for multiple agencies, including Waka Kotahi New Zealand Transport Agency, GNS Science, Environment Canterbury and Marlborough District Council to enable effective capture of aerial photography, LiDAR and bathymetry. Pulling together the data requirements of multiple agencies, and securing joint funding is where LINZ can contribute to support agencies responding to an event.

Key datasets

Twelve datasets have been identified as playing a critical role in decision-making in the four stages of emergency management: risk reduction, readiness, response and recovery, plus climate change.

The 12 datasets which cover people, property, transport, rivers and land were identified by LINZ working with NZGIS4EM (New Zealand GIS for Emergency Management), and representatives from central and local government agencies including the National Emergency Management Agency.

Work is underway with the organisations responsible for these datasets to make sure the data is accessible and available to support emergency management.

Data capture in emergency events

In addition to improving the key datasets, LINZ staff are available during and after emergencies to coordinate the collection and supply of aerial photography, satellite imagery, LiDAR elevation data, and bathymetry (detailed sea-bed mapping).

This allows agencies responding to or recovering from an event to record the scale of damage and assess impacts. For example, the extent of a flood, or the loss of farmland after a fire.

Discovering useful datasets –

With so many geographic datasets available online it can be difficult and confusing for organisations to work out which datasets will be helpful particularly when preparing for an emergency event.

LINZ is working with the Department of Internal Affairs (DIA) to provide feedback on the platform to enhance its usability and improve the discoverability of natural hazard and other emergency related datasets.


Can you contribute? 

If your organisation has geographic data which could be useful in in the preparation for, response to, or recovery from an emergency, learn more about the benefits of publishing open data, then create a publishing account or contact for more information.
