Resilience and climate change

Toitū Te Whenua helps coordinate and promote the use of geographic data as New Zealand prepares for and responds to emergency events and climate change.

After the 2016 Kaikoura Earthquake, we coordinated data requirements to enable the effective capture of aerial photography, LiDAR and bathymetry. This work included Waka Kotahi New Zealand Transport Agency, GNS Science, Environment Canterbury and Marlborough District Council.

Key datasets

Twelve datasets play a critical role in decision-making in emergency management risk reduction, readiness, response and recovery, as well as responding to climate change.

The 12 datasets cover people, property, transport, rivers and land. These datasets were identified by a group including Toitū Te Whenua, GEMA (Geospatial Emergency Management Aotearoa), and central and local government agencies including the National Emergency Management Agency.

Work is underway 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, Toitū Te Whenua staff are available during and after emergencies to coordinate the collection and supply of:

  • aerial photography
  • satellite imagery
  • LiDAR elevation data
  • bathymetry (detailed sea-bed mapping).

This allows agencies to record the scale of damage and assess impacts. For example, we can help them determine the extent of a flood or the loss of farmland after a fire.
