Geographical Centre

In geography, the centroid of the two-dimensional shape of a region of the Earth's surface (projected radially to sea level or onto a geoid surface) is often known as its geographical centre. There has long been debate over the methods of calculation of the geographical centres of various countries and regions, such as whether to include offshore islands, and in that case, if the islands should be moved towards the mainland, making it possible to build a connected 2D model of the country and identify the geographical centre as the centre of gravity (equilibrium point) using a needle. An alternative to defining the geographical centre as the centroid is to define it as the point farthest from the boundary of the country (either the sea, or, in the case of constituent countries, a land border), this is similar to the pole of inaccessibility (place furthest from a coastline). These methods give quite different answers.

Famous quotes containing the words geographical and/or centre:

    Men’s private self-worlds are rather like our geographical world’s seasons, storm, and sun, deserts, oases, mountains and abysses, the endless-seeming plateaus, darkness and light, and always the sowing and the reaping.
    Faith Baldwin (1893–1978)

    Freedom to think our own thoughts, freedom to utter them, freedom to live out the promptings of our inner life ultimated in this convention, was termed a monstrosity of the 19th century. What was it?—the legitimate out-birth of the eternal law of progress. This reformation underlies every other; it is the only healthful centre around which hope of humanity can revolve.
    Harriot K. Hunt (1805–1875)
