In English, null means nothing, nil, empty or void. In computing, null is a special value for nothing, an empty value. In geography, null tends to be what you get when you've been unable to geocode a place or an address and haven't checked the geocoder's response. What you end up with is a pair of coordinates of 0 degrees longitude and 0 degrees latitude, a point somewhere in the middle of the Atlantic Ocean, south of Ghana and west of Gabon. It's here that you'll also find Null Island, if you look hard enough.

The website for the Republic of Null Island (like no place on earth) says this about the island's location ...

The Republic of Null Island is one of the smallest and least-visited nations on Earth. Situated where the Prime Meridian crosses the Equator, Null Island sits 1600 kilometres off the western coast of Africa.

... but Null Island is an in joke created by Nate Kelso and Tom Patterson as part of the Natural Earth data set in January 2011.

We've become firmly accustomed to the instant gratification of Internet Time, which can be roughly summarised as "I want it now, dammit". Nowhere is this more evident than in maps. If something is wrong on a map, we expect it to be fixed. Now. Ten or so years ago, it would be common to wait somewhere between 12 and 18 months for a map's updates to be collected, validated and published. These days, thanks to our modern digital maps, we get our updates in more or less Internet Time and that means fast. It hasn't always been that way.

Although waiting over a year for a map update seems almost unthinkable now, consider for a moment having to wait almost half a century for a map to be updated. Yet this is what happened in the curious cartographical case of the Island of California.

I should state up front that I've been to California, quite a few times. The weather is fine (apart from San Francisco's fog), it's home to the technical hub of Silicon Valley and the local food and wine are rather good. It is most definitely not an island and what's more, there's a distinct lack of tribes of beautiful Amazonian warriors wielding gold tools and weaponry. Yet in 1510, Spanish author Garci Rodríguez de Montalvo published a novel entitled Las Sergas de Esplandián, or The Adventures Of Esplandián, which mentions the Island of California, populated by the aforementioned female warriors. The name and concept of an island stuck and early Spanish explorers of what we now call Baja California were convinced the new territory they had found was part of the Island of California.

In retrospect, early maps of the New World actually got the geography of California right. Both Mercator, he of web map projection controversy, in 1538 and Ortelius, in 1570, made maps that correctly showed California as a peninsula.
