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.
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.
