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 Kaikōura 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 data improvements

National key 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 14 datasets cover people, property, transport, rivers, place, land and coasts. These datasets were identified by the emergency management geospatial community represented by GEMA (Geospatial Emergency Management Aotearoa), the Geospatial Special Interest Group and 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.
