DML delivers LINZ HS57 Nautical Charting Survey
DML recently delivered The Approaches to Napier Hydrographic Survey (HS75) to Toitū Te Whenua Land Information New Zealand (LINZ). Kate Downes, Surveyor In Charge (SIC) delivered 8 Tb of data which included raw data, bathymetric surfaces, water column data, backscatter imagery and numerous reports. The data will be used to update nautical charting products in the region.
Data capture and fieldwork for this project was conducted from October to November 2022 and consisted of 390 sounding hours, 2730 nautical line miles or 252 km². The reporting phase for nautical charting surveys is quite extensive and, in this case, ran from December 2022 to June 2023.
DML would like to congratulate Kate and her team for their impressive effort delivering a high quality survey.
Preparations are underway for DML to undertake the next LINZ survey, Approaches to Gisborne (HS76) commencing in October 2023.
