## Import, Plot and Analyze Bathymetric and Topographic Data
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.
## Installation
```R
# Install marmap from CRAN
install.packages("marmap")
# Or the development version from GitHub:
# install.packages("pak")
pak::pak("ericpante/marmap")
```

Making and using bathymetric maps in R with marmap.
## About the logo
The logo was made based on the recommendations of R Packages (2e). The wave in the background is part of "[The Great Wave off Kanagawa](https://en.wikipedia.org/wiki/The_Great_Wave_off_Kanagawa)" (神奈川沖浪裏) by Katsushika Hokusai (1831), based on the Ukiyo-e technique of woodblock printing. It’s a lovely connection between my love for woodworking and my fascination with the ocean. It is also a reference to the fact that marmap was originaly designed to help with oceanographic cruise preparation, and I have used it both on land and at sea. Check out [DAUNPAPUA](https://epante.wordpress.com/daunpapua/), an oceanographic cruise on the exploration of deep-sea biodivesrity in Papua New Guinea, which was prepared using marmap.
