Mapping Trade Routes from Ship Logs

David Hopp sent me a note about his new website, CLIWOC Repurposed. “The Climatological Database for the World’s Oceans 1750-1850 (CLIWOC) was a project sponsored by the European Union from 2001 through 2003. Meteorological data was extracted from the logbooks of ships, sailing primarily under the flags of Great Britain Spain, The Netherlands, and France. […] The intended purpose of this present web site is to explore visualiztions of the CLIWOC data not for their meteorological value, but to illustrate the trade routes of the ships of the four countries.” Which he does with a set of maps, one for each country, showing that country’s Atlantic trade routes.
