Natural Earth describes the entity as a "1 meter square island" with "scale rank 100, indicating it should never be shown in mapping ." The name' Null' refers to the two 0 co-ordinates, both of which are sometimes known as null in mathematics . </P> <P> Although intended humorously, the fiction has a serious purpose and is used by mapping systems to trap errors . Such errors arise, for example, where an image artifact is erroneously associated to the location by software which cannot attribute a geo - position, and instead associates a latitude and longitude of "Null, Null" or "0, 0". Null Island was developed as an idea in 2011 or slightly earlier . Since then, numerous web pages have documented this fictional landmass's flag, geography, and history . </P>
