historic shipping routes: a webmap

We all know: Black is beautiful. So is this map from Andrew Zolnai. But besides the stunning Stamen toner background map he also shows the significant amount of 260.000 points on one map: historic logbook entries of ships.

You can select nations and times and identify each point of this nice map and see the meta data of each logbook entry. So you can easily see the direct trading routes from and to the oversea areas and colonies of each country, you can imagine the triangular trade and you may also discuss the question who was the emperor of the seas 😉

As the frontend he uses the output of the theme wizard from  MapCentia. According to his blog-entry he hosts the data on an Amazon Web Service and it is all combined using the GeoCloud 2 stack from MapCentia. These services are not for free: If you quit the service, the map is gone…

Andrew also added two individual routes. First the trips from Captain James Cook are shown on the map. You can see clearly the first and second route but due to the fact that logbook entries are recorded there is a little gap in the data. The second route is from Jean François de Galaup, comte de Lapérouse who also started to do a round trip but who stopped his journey in Australia.

  • … thanks for this kind review, Riccardo!

    the point I made on argis.com is: “This dataset will show, for example, that Captain Cook’s logs miss his historical landing at Botany Bay in Eastern Australia, as well as his last voyage ending with his demise in Hawaii. Dennis Wheeler, adjunct at the National Maritime Museum in Greenwich UK, revealed the following: even though the Royal Navy enforced strict guidelines to record weather and location, James Cook was notoriously lax in this; the CLIWOC team simply couldn’t transliterate some of his ships logs! This is not only a very early example of data standards, but also a current illustration of why standards are important.”

    And on my original zolnai.ca: “As the map indicates, French navigator Capt. de la PĂ©rouse’s ships – the Astrolabe and the Boussole – disappeared without trace offshore Australia. His original intent was to claim it for the French king, and he almost took a young Napoleon as his surveyor (think about it)!”
