pygmt.datasets.load_hotspots

pygmt.datasets.load_hotspots()

Load a table with the locations, names, and suggested symbol sizes of hotspots.

This is the @hotspots.txt dataset used in the GMT tutorials, with data from Mueller, Royer, and Lawver, 1993, Geology, vol. 21, pp. 275-278. The main 5 hotspots used by Doubrovine et al. [2012] have symbol sizes twice the size of all other hotspots.

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 with columns “longitude”, “latitude”, “symbol_size”, and “placename”.
