According to the researchers, darker areas on the map are more remote than lighter areas. So, for example, look at Australia’s coast versus its interior; or, check out the northern tip of Britain versus its southern areas.
Their calculation of remoteness is based on how long it takes from any one point on land to travel by land or by water to the nearest place with at least a population of 50,000 inhabitants. Remoteness, however, needn’t only be about actually travelling somewhere. Remoteness as a concept is as much about (lack of) connectivity via technologies (Internet, mobile phone, etc.) and an individual’s needs (one person’s remoteness is another’s paradise) as it is about getting to a large town. Still, what nice fiery-coloured maps!
