⚠️There's a newer version (1.0.10) of this package.Take me there.

marmap (version 0.9.4)

Import, Plot and Analyze Bathymetric and Topographic Data

Description

Import xyz data from the NOAA, GEBCO 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.
