In April 2020, CoLab entered into an agreement with iXblue Pty Ltd to complete a LiDAR (Light detection and Ranging) survey throughout the Waikato region.
The latest LiDAR technology is being used to collect earth surface data to create highly detailed 3D maps and models of the landscape.
The survey was completed in April 2021 and the massive task of processing the data then commenced. After intensive quality control, the full data set will be made freely available to the public by April 2023.
CoLab on behalf of the 10 councils, has secured funding of $1.4 million from the Provincial Growth Fund (PGF) and approximately $133,000 third party funding for the region. CoLab will be running the project which is part of a national LiDAR programme coordinated by Land Information New Zealand (LINZ).
The councils involved in the initiative are Waikato Regional Council and Hauraki, Matamata-Piako, Ōtorohanga, South Waikato, Taupō, Thames-Coromandel, Waikato, Waipā and Waitomo district councils.
Hamilton City Council has already recently acquired LiDAR data for the city. This will be joined with the new data to provide a contiguous regional data set of over 25,000km2.
CoLab Chief Executive Kelvin French says it is fantastic the councils have contributed funding to support the project. He is also grateful for the contributions from the following organisations who are co-funding the initiative: WEL Networks, Environmental Research Institute, EQC – Earthquake Commission, Waikato River Clean Up Trust, Lincoln Agritech and Mercury NZ Ltd.
LiDAR provides precise laser measurements of the earth’s surface with the data used to create highly accurate 3D maps of the land.
The data enables better management of natural hazards, such as flooding, erosion and sea level rise. It provides farm-scale land information to benefit the agriculture and forestry sectors as well as being used for many other planning purposes. It is also widely used for development, engineering, architecture and design applications by the private sector.
