Mapping Resources

Like many geoscientists, the Generic Mapping Tools (GMT) is my bread and butter for making virtually all of my plots. This package is easy to install with homebrew, is extremely flexible, and easy to use after a bit of a learning curve. However, it only comes with limited datasets, such as coastlines, and therefore we often have to hunt down map resources for around the interwebs and colleagues. On this page are links to my most commonly used mapping resources and some of my favorite example scripts.
