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.

The Making of the Atlantic Neptune

We’ve heard about The Atlantic Neptune, an 18th-century multi-volume atlas of the eastern shores of North America produced by J. F. W. des Barres. Jeffrey Murray returns to the pages of Fine Books and Collections magazine (see previous entry) to explore the making of The Atlantic Neptune, including Des Barres’s surveys of Nova Scotia and New Brunswick. Thanks to Rebecca Barry for the tip.

Live Marine Traffic Maps

Since 2004, the International Maritime Organization has required all vessels of 300 or more gross tons to carry an AIS transponder, which transponder transmits position, speed and course and other information about the ship. MarineTraffic.com takes that data and plots it on a map. The data is updated every hour — close enough to real-time. Think about it: this is a near-real-time map of every ship on the planet above a certain size. Mind-boggling. Via Cartophilia.

Garmin Recalls Data Cards Showing Inaccurate Water Depths

It’s one thing if your road map has an error in it, quite another if your aviation or nautical maps have an error in them. It can be catastrophic. Which is why, PC World reports, Garmin is recalling data cards that show incorrect water depths off the coasts of Sweden and Denmark. It’s never a good thing when your charts say that the water is deeper than it actually is.

ESA Maps European Shipping Routes

The European Space Agency has released maps showing European shipping routes, based on seven years’ worth of radar tracking. The ESA also correlates these routes with NO2 emissions; marine engines apparently burn rather dirty fuel. Via La Cartoteca….  •  Continue reading this entry.

Great Circles

About.com’s Amanda Briney has a primer on great circles. A great circle is the shortest distance between two points on a sphere; sailors and aviators use great circles to get the fastest and most efficient route from point A to…  •  Continue reading this entry.

The Analog GPS

The Analog GPS: “Take your batteries and slavish dependence on other high-tech flummery and heave it overboard. With this device, you can pinpoint your location anywhere on earth and not be reliant on dodgy bits of information being projected…  •  Continue reading this entry.

The Atlantic Neptune

The Atlantic Neptune, “a magnificent four-volume atlas of sea charts and views of the east coast of North America, published during the American Revolutionary War by Joseph Frederick Wallet Des Barres (1722-1824),” has been scanned and put online by…  •  Continue reading this entry.

Zoomatron

Zoomatron uses MapCruncher to overlay nautical charts on top of the Virtual Earth interface. Massachusetts and Washington states. The method reminds me of what Skyvector.com did with aeronautical charts. Via Windows Live Local/Virtual Earth.

NOAA Nautical Chart Downloads

NOAA’s nautical charts are available for free download as raster images in BSB format, GPS Tracklog reports. Rich mentions that the files can be used in OziExplorer; NOAA has a list of software and an online viewer….  •  Continue reading this entry.

Agnese’s Portolan Atlas

I can’t believe I haven’t mentioned portolan charts on The Map Room yet. In that vein, don’t miss peacay’s big post on BibliOdyssey about Battista Agnese’s sixteenth-century Portolan Atlas, scans of which are available on several sites….  •  Continue reading this entry.

GPSNavX

As you know, I like to keep track of what Mac mapping or GPS software is out there. Here’s another one: GPSNavX, which is boating software — both navigation and GPS — for OS X. The folks behind this one…  •  Continue reading this entry.

Boating Software

I don’t think there’s a single area of mapping where software isn’t displacing traditional maps. That goes for navigational charts, too. Motor Boating has a review of recent navigation software for recreational boaters. Some of it’s quite pricey, but let’s…  •  Continue reading this entry.
