Nautical charting surveys are undertaken to ensure safe ship navigation by knowing the precise depths and therefore the under-keel clearance for transiting vessels around New Zealand’s busy coastline and shipping lanes. Land Information New Zealand is tasked with keeping New Zealand’s charts up to date. We are one of two panel providers who undertake regular surveys to achieve this.
We are also the only New Zealand company to provide these services to the Royal Australian Navy.
Nautical charting surveys are some of the most complex and comprehensive surveys we undertake due to their precise and exacting standards.
DML personnel hold IHO Cat A and CPHS Level 1 Certifications; mandatory for meeting Land Information New Zealand requirements.
Erosion and coastal monitoring surveys are normally required along exposed coastlines, riverbanks and lake shorelines to assess impacts of sedimentation on marine life and to predict impacts of extreme weather events on coastal development. DML undertakes many of these surveys for local and regional councils and coastal scientists.
