Antarctica was the last continent to be discovered, and the first confirmed landfall was on January 24, 1895. However, most discussions of "early" world maps seem to peter out well before that, such as this Wikipedia article which only goes up to 1630.

The situation is muddied even more by the fact that Antarctica (known then as Terra Australis) appeared on many world maps before it was even discovered, such as this 1570 map. However, this is based on arguments from legends and various erroneous information, rather than on any actual evidence.

Surely after humanity first set foot on the "last continent", it wasn't long before they started mapping the real shape of it. When was the first map produced based on this real information (regardless of whether it was actually "accurate" in the era before we had artificial satellite technology etc)?

This question is made even more important by the fact that a world map incorporating this shape would be "largely" complete, although world maps would arguably not really be complete (in terms of approximate landmass shapes) until the first whole maps of Severnaya Zemlya were completed in 1932.

    Coastline? With or without the ice shelves? Interior? Below the snow/ice (several kilometres thick in places, and masking valleys and mountains)? What do you consider would qualify as "accurate"?

  • Also - the map at i-cool.org/?tag=route shows many visits by ships before 1895, so much of the coastline would have "mapped" to some degree before actual landfall

    @HorusKol I didn't use the word "accurate" in my question; I referred to "based on real evidence". I would have thought by the term "shape" it is obvious I'm just talking about the coastline and not the interior?

  • far enough - but why do you need to have landed on it to map the coastline?

  • FWIW, January 1895 was not the first confirmed landing; according to Headland's 'Chronology of Antarctic Exploration', it was "probably the sixth" on the mainland and the second in that general area - the first in Victoria Land had been in 1853. In the Peninsula region, the first landings on the mainland may have been as early as 1821, though they're not well documented and may have been visiting the Palmer Islands.

General answer: it will probably depend what you define as "the shape". Ultimately, once landfall was made on opposite coasts (1820-1840), and land was proven to be there, it was a matter of looking at all the places a ship had sailed through without hitting anything, concluding that the coastline must be further south than that, and drawing in a dotted line to taste.

As Antarctica is basically circular, this worked out pretty well - the inferred coastline was broadly similar to what was actually there.

As successive expeditions reached new stretches of the coastline, the estimates were refined and the known bits were drawn in, until by the late-1940s early-1950s the whole coastline was charted.

Map as of 1911, for example: (source; more examples). Note that this is basically correct in its outline save for the spurious "second peninsula" in the Weddell Sea (no idea why that got in there) and a certain ambiguity as to whether Graham Land connected to the mainland or not.

Map of Antarctic discoveries, 1911

The more precise answer: according to a helpful article in Polar Record, 1844.

The first map to use the new place name was published in 1843, and the first map to show a complete outline of the continent, estimated from expedition reports, was produced in 1844.

Bulkeley, R. (2016). "Naming Antarctica". Polar Record, 52(1):2-15

The four maps displayed in that article are shown below. Note that the map above needs to be rotated ~140° counter-clockwise to match the orientation of these maps.

  • Though I believe that even today, most common maps aren't accurate (for a given value of accurate, of course), since they show the outline of the continent as the edges of ice shelves, rather than where sea would meet rock.

    @jamesqf IME, most maps that show anything beyond a simple silhouette outline do tend to distinguish between (ice-covered) land and ice shelves - usually by shading them, eg commons.wikimedia.org/wiki/File:Antarctica.svg Commented Feb 10, 2016 at 19:43
  • (I look at these maps all the time, though, so my sample may be skewed!) Commented Feb 10, 2016 at 19:46
  • I was thinking more like this en.wikipedia.org/wiki/West_Antarctic_Ice_Sheet#/media/… where a lot of the continental rock is actually below (current) sea level.

    @jamesqf I love those maps, really counterintuitive to look at :-) My feeling is that given the Antarctic context, where ice is a permanent & universal feature, they're not really more 'accurate' - it's a bit like saying normal maps are inaccurate because they include soil and mud, not just bedrock.

A very interesting question, as it turns out.

The coast of Antarctica wasn't definitively sighted until about 1820, so no globe until then would have featured it.

I found this pocket globe made by Abel Klinger in I believe 18801 that shows the barest outline of some of the coast of Antarctica. Examining some globes from the same manufacturer in 1855, I can't see any hint of it. One would imagine there must be one earlier than 1880 though2.

1- The text just says "end of the 19th Century". However, I've found other references to his pocket globes dated 1880. So I could be a few years wrong here.

2 - Vastly complicating this search is the fact that people don't like to show pictures of largely blank areas of a globe.

    This may be one of those questions we have to triangulate in on. Given that, I figure I can at least put down a point.
