Aerial lidar surveys were utilised to define the critical intertidal MHW and MHWS lines on a large rural property within Auckland City. These tidal lines define critical legislative and cadastral limits and are required when developing land, they define the seaward boundaries and provide the basis for the Queens Chain and its equivalents.
The tidal lines are not contour lines, there elevation changes due to the energy sapping or charging effects of mangroves estuaries and stream flows. By using high definition lidar we can save our clients a lot of time and obtain a higher resolution and more accurate outcome.
Envivo’s lidar knowledge is helping our clients succeed.
