LiDAR Cook Islands

The Cook Islands LiDAR Project is a national initiative using cutting-edge mapping technology to capture the Cook Islands in unprecedented detail. Spanning 14 islands, the project is providing new insights into our land, reefs, lagoons, and infrastructure to support smarter planning, stronger climate resilience, and sustainable development for generations to come.

Explore high-resolution LiDAR products, 3D terrain, aerial imagery and geospatial information from across the Cook Islands – all through your web browser.

What is LiDAR?

LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser pulses from an aircraft to accurately measure the shape and elevation of the Earth’s surface and, in some areas, reefs and lagoons.

By collecting millions of measurements, LiDAR creates highly detailed three-dimensional maps that provide a new perspective on the Cook Islands and support better understanding of our natural and built environments.

Why is LiDAR Important?

LiDAR helps us better understand our islands and prepare for the challenges that lie ahead. By providing highly accurate information about the shape and elevation of the land, reefs, and coastlines, LiDAR gives us the knowledge needed to make smarter decisions for our communities and future generations.

LiDAR data can help us:

  • Better understand areas at risk from flooding, storm surge, and coastal erosion
  • Plan and maintain roads, buildings, and other important infrastructure
  • Strengthen disaster preparedness and emergency response efforts
  • Protect and manage our natural environment, including watersheds, reefs, and vegetation
  • Support sustainable land use and development planning

By creating a clear and accurate picture of the Cook Islands today, LiDAR will help us monitor change over time and build a more resilient future for all Cook Islanders.

Data Products and Access

The Cook Islands LiDAR Project has generated a range of high-quality geospatial datasets to support government planning, research, environmental management and infrastructure development. These include elevation and terrain models, aerial imagery, contours, bathymetry maps and other technical datasets.

These products can now be explored through CookGeo – the Cook Islands GeoPortal, making it easier to search, view and understand geospatial information from across our islands without specialised GIS software.

While CookGeo is accessible to everyone, technical datasets and downloadable products are primarily intended for government agencies, researchers, technical personnel and partner organisations to support planning, analysis and informed decision-making.
