pygmt.datasets.load_sample_bathymetry

pygmt.datasets.load_sample_bathymetry()

Load a table of ship observations of bathymetry off Baja California as a pandas.DataFrame.

This is the @tut_ship.xyz dataset used in the GMT tutorials.

The data are downloaded to a cache directory (usually ~/.gmt/cache) the first time you invoke this function. Afterwards, it will load the data from the cache. So you’ll need an internet connection the first time around.

Returns:

data : pandas.Dataframe

The data table. Columns are longitude, latitude, and bathymetry.
