CSIRO Norfolk Island Water Resource Assessment Project update – Aerial lidar

Thursday, August 29, 2019


During the week of the 9th September residents and visitors to Norfolk Island may notice an airplane flying over Norfolk Island (weather permitting). The plane will be flown by Landpro, a New Zealand based company with specialised skills in high resolution aerial photography and lidar mapping. CSIRO has commissioned Landpro to acquire ‘lidar’ over Norfolk Island as part of the Norfolk Island Water Resource Assessment (NIWRA) project.


Lidar is the acronym for ‘Light Detection and Ranging’. It is a remote sensing method that uses light in the form of a pulsed laser to generate precise, three-dimensional information about the shape of the Earth and its surface characteristics.

As part of the NIWRA project, aerial lidar will be acquired to provide a high-density topographical map of the island’s terrain, helping to inform the hydrological assessment. It will be a high value legacy dataset for future use by the people of Norfolk Island.

Lidar data has already been acquired for many urban and coastal areas of Australia and New Zealand, large parts of the Murray-Darling Basin and other major river systems, and many other parts of the world. It is now considered a fundamental baseline dataset and has a wide variety of uses including hydrological assessments and modelling, agriculture, urban and infrastructure planning and design, archaeology, ecology and natural resource management, including high resolution erosion mapping and vegetation mapping. To make the most of the lidar activity in September, Phillip and Nepean islands are being included to create a valuable dataset for future use by Norfolk Island for heritage and environmental management purposes.

Residents may recall previous aerial survey activity using lidar. In 2015-16, the Royal Australian Navy’s Hydrographic Service used Laser Airborne Depth Sounder (LADS) to acquire bathymetric data in the vicinity of Norfolk, Phillip and Nepean islands for the purposes of improving nautical charting in the area for safe navigation of coastal and commercial shipping. This project did not include Norfolk Island itself and was not focused on fresh water resources.

Our colleagues from Landpro, Andy Burrell, Mike Borthwick and Grant Bissett, are looking forward to visiting Norfolk and Philip islands. If people would like to have a chat with Andy, Mike and Grant they intend on having dinner at the Bowling Club on Thursday 12th September from about 6:30 pm. They would love to meet some residents of the island and talk about their work.

For more information on the NIWRA project, including copies of the Fact Sheet, please visit our website www.csiro.au/norfolkwaterassessment. If you have questions regarding the lidar activity please contact our local team member Snowy Tavener on 50558 or email the NIWRA Project lead cuan.petheram@csiro.au.

The CSIRO NIWRA project is funded by the Department of Infrastructure, Transport, Cities and Regional Development.
