Resumen

This note presents a largely automated method to create bathymetrically safe,legible, scale appropriate depth contours for Electronic Navigation Charts (ENCs)using the CARIS BASE Editor version 4.4 software installed in the AustralianHydrographic Office (AHO). The method is suitable for contouring modern high densitymulti-beam survey data as well as sparser single beam data (or a combination ofboth). Being a largely automated process, the time required to incorporate newbathymetric data into navigation products is significantly reduced. The methodfacilitates finer resolution depth encoding within ENCs and therefore a more realisticportrayal of safe water to the mariner.
