$800,000 from Govt announced for 3-D mapping of Northland

Economic Development Minister Simon Bridges and Primary Industries Minister Nathan Guy have announced government funding of up to $800,000 for 3-D aerial mapping of Northland to provide the region with highly accurate geographical data to make better development decisions.

LiDAR is a remote sensing tool which uses laser pulses to generate large amounts of highly accurate geographical terrain data.

Bridges said this would be the most comprehensive LIDAR exercise ever undertaken in New Zealand. The high-quality mapping data produced would provide a blueprint of the whole region.

“It will produce data that is ten times more accurate than what is currently used, and can have a wide range of uses from forest inventory, floodplain mapping, urban planning and coastal engineering to its use for the design of powerlines, roads, railways, mines, farms and land developments.”

Guy said the data would provide authorities with more confidence to progress infrastructure projects and deliver better, more cost-effective planning and a better understanding and ability to plan for sustainable land management.

“The data can be used by forestry companies to help plan their logging operations, horticulture companies for sustainable land management and by public and private operators to plan pest control.

“On the farm it can be used for creating topographic maps of fields and for crop mapping in vineyards and orchards. It will be a valuable tool for decision-makers to use in working out how to get the best use of their land.

“LIDAR also helps with detailed hazard planning and preparation by identifying any changes to land formations, water courses and physical structures after a natural event. After the Kaikoura earthquake it was used to show how far the impact extended out to sea.”

Funding for the Northland LIDAR project comes from the government’s Regional Growth Programme, co-led by the Ministry for Primary Industries and the Ministry for Business, Innovation and Employment. Land Information New Zealand has also contributed funds.

The government’s funding has been collectively matched by the four Northland councils.

LIDAR surveying is expected to start within the next few months and be completed in 2018.
