marmap (version 1.0.12)

Import, Plot and Analyze Bathymetric and Topographic Data

Description

Import bathymetric and hypsometric data from the NOAA (National Oceanic and Atmospheric Administration, ), GEBCO (General Bathymetric Chart of the Oceans, ) and other sources, plot xyz data to prepare publication-ready figures, analyze xyz data to extract transects, get depth / altitude based on geographical coordinates, or calculate z-constrained least-cost paths.
