| The distance in a geographic context is a measure of the length between two points on the surface of the earth. It is always dependent on a metric, ie. the way of measuring size. For example, distance can be measured in a straight line on an area considered flat, or by taking into account the roundness of the earth (orthodromic distance). The distance measured along a network of paths will have a different value than a straight path (for example, we call the distance measured in a orthogonal plane in a city the Manhattan Distance). | The distance in a geographic context is a measure of the length between two points on the surface of the earth.
