The 3D Coastal Mapping (3DCM) programme is using a combination of Light Detection and Ranging (LiDAR) and multi-beam echo sounder (MBES) technologies to map up to 40% of the New Zealand coastline.

Natural hazard risk modelling is about figuring out how events like earthquakes, floods, or tsunamis could affect people, property, and the environment. It looks at how likely these events are, how strong they might be, and what’s in harm’s way. This helps communities and organisations plan ahead, reduce risks, and respond better when disasters happen.

In 2022 the Government implemented its first National Adaptation Plan (NAP) which seeks to put in place measures for New Zealand to adapt to the impacts of climate change and address the risks identified in the National Climate Change Risk Assessment (NCCRA).

The National Aerial LiDAR Base Specification provides a foundation for public sector LiDAR procurement.

The 3D Coastal Mapping (3DCM) programme will improve key baseline data to help the country prepare for the impacts of climate change and understand how our coastline is changing.

The 3D Coastal Mapping Programme (3DCM) is a key initiative under the National Adaptation Plan, developed in partnership with the Ministry for the Environment. It delivers wide-ranging benefits across economic development, infrastructure resilience, hazard and risk modelling, climate adaptation planning, the environment and ecosystems, and safety of life.

3D coastal mapping helps the economy by giving better information for planning and decision-making. It supports smarter infrastructure development, helps prepare for natural disasters, and improves safety at sea. These benefits lead to saving money, lowering risks, and boosting economic activity in coastal areas.

Answers to common questions about the 3D Coastal Mapping Programme grouped into categories.

Access road, address and places data through the LINZ Data Service.

Toitū Te Whenua has established a network of sea level monitoring sites at 18 locations around New Zealand and Antarctica.

Local and central government agencies can request access to district valuation roll (DVR) datasets.

The New Zealand Property Spine captures common data for every property in the country to support statistical analysis, GIS, and planning.

Infrastructure like roads, railways, airports, hospitals, ports, and insurance is at risk from things like sea-level rise, storms, erosion, and flooding. This includes homes, public spaces, water and energy systems, transport, communication networks, waste services, and coastal protection structures.

Our partnerships with regional councils include the publication of orthorectified historical surveys through LINZ Basemaps. We also maintain the Crown Aerial Film Library, an extensive, high-resolution collection of digitised film negatives from Crown and private aerial surveys.
