The IHO-IOC GEBCO Cook Book.

Abstract

GEBCO aims to provide the most authoritative publicly available bathymetric data sets for the world's oceans. In order to assist and encourage further participation in bathymetric grid development work, GEBCO has created a technical reference manual, the IHO-IOC GEBCO Cook Book, on how to build bathymetric grids. One of GEBCO's products is a global gridded bathymetry data set. It is based on seafloor depths from ship soundings, and where there are no soundings, depths are interpolated using estimates from satellite altimetry as a guide. The global grid is periodically updated by incorporating additional bathymetric survey data, new compilations, and improved data.

The Cook Book is divided into three main sections "Gridding Examples" written for beginning users desiring to straightaway produce a grid from xyz data, "Fundamentals" which gives a more in-depth look at topics related to preparing, processing, and gridding xyz data, and "Advanced Topics" which contains discussions more experienced users may find useful.

With this document, "The IHO-IOC GEBCO Cook Book," we hope to enable more people to contribute data and gridded compilations to GEBCO.
