Background
Key data sets have been identified as playing a critical role in decision-making in the four stages of emergency management: risk reduction, readiness, response and recovery, and climate change.
The datasets cover people, property, transport, rivers, place, land and coast. They were identified by our geospatial emergency management customers working with GEMA (Geospatial Emergency Management Aotearoa) the Geospatial Special Interest Group, and representatives from central and local government agencies including Civil Defence Emergency Management Groups and the National Emergency Management Agency.
Key data improvement plan
Toitū Te Whenua is working with the owners of these datasets to ensure the data is accessible and available to support emergency management. An improvement plan for 2023/24 has been developed for each dataset.
Overview
The latest 'Key datasets for resilience and climate change overview' includes a summary of each of the datasets. This includes the authoritative source and lead agency responsible for maintaining the data. You can also find out about the data improvements implemented to date, and what our customers in the emergency management community have identified as their highest priorities for future improvements.
