I am writing an epidemiology paper for an academic journal, and would like to have a figure showing the map of a geographical region of interest.
My current map was generated with OpenStreetMap data, from the
get_stamenmap function provided by the
ggmap package in R.
However, such maps have copyrights, and they won't be accepted by most academic journals I am interested in publishing in. Does anyone know some good tools to produce pretty, copyright-free maps and possibly programmatically? Bonus points if they are produced through R.
I would also appreciate any other map-related hints or suggestions.
