The project's journey into 3D

City Rail Link (CRL) and the Government’s lead agency for property and land information have embarked on a ground-breaking collaboration to improve industry compliance with land survey standards.

Toitū Te Whenua Land Information New Zealand (LINZ) and CRL Ltd are collaborating to ensure the integrity of ownership and protection of not only the railway stations and tunnel infrastructure but also the subsoil surrounding the infrastructure. This ensures that future use of the land and subsoil, be it private or public property, or road, is minimally impacted by the tunnel and rail stations.

LINZ Principal Cadastral Surveyor, Mike Morris, said the CRL survey is not without its challenges: “The magnitude of the project is not so much the huge quantity of data coming through, but the complexity of the information which makes it such a significant project.

“New Zealand was ground-breaking in its introduction of a two-dimensional cadastre in the early 2000s; the current redesign of the system, Landonline, is the start of a journey to a fully 3D land information system.”

Rick Galli, CRL Head of Property, said the collaboration project has only just commenced and will be a long journey: “Geo-referencing in 3D is really exciting and it will be fascinating to see where LINZ is going with it.”

Both public entities share a duty of care to look after New Zealand’s land and environmental resources, so they are sustained for future generations.
