Is it a bird?! Is it a plane?! Yes – it is a plane! The LINZ 3D Coastal Mapping programme is getting underway this week and you may spot our mapping planes in your area 🛩️
LINZ’s exciting, multi-year programme of work to map up to 40% of our coastline in 3D and install 10 global positioning receivers at tide gauges around the coast will help the country mitigate the future impacts of climate change 🌡️
Scientists, modellers and planners will use the high-definition LiDAR data to understand how our country could be impacted by sea-level rise, future tsunami, and storm surges from weather events 🌊
Once the information is captured and mapped it will provide a valuable baseline for future studies of how our coastline is changing over time.
We are prioritising parts of the coastline that are the most populated, or where key infrastructure is vulnerable to the impacts of climate change.
Our suppliers, NV5 Geospatial and Woolpert Asia-Pacific, will begin mapping the following areas this summer: Bay of Plenty, Gisborne, Hawke’s Bay, Wairarapa, Wellington, Manawatu-Whanganui, Taranaki, Southland, Dunedin, Oamaru, Timaru and Westland are up first!
We will keep you posted when we know more about their plans.
Planes need to fly at 500m above ground to capture great data, and they use pulsed light LiDAR technology to build up a 3D picture of the coast. You may hear or notice these planes in your area.
Data from this programme will be freely and publicly available on the LINZ Data Service once it is processed 🖥️
