Coastal surveying
Coastal & marine surveys in Northland
Specialist survey work where land, tide and local datums meet.
Clear information.
Practical next steps.
Coastal and marine surveying can require tidal observations, local benchmarks and careful conversion between chart information and local height datums. GSL’s Waikare Inlet work included a topographical survey, tidal boundary information and plans for consented jetty and riparian works.
