where does 0 latitude and 0 longitude meet
Null Island Null Island is a fictional island in the Gulf of Guinea added to the Natural Earth public domain map dataset,[1] located where the equator crosses the prime meridian, at coordinates 0°N 0°E﻿ / ﻿0°N 0°E﻿ / 0; 0.[2][3][4] Natural Earth describes the entity as a "1 meter square island" with "scale rank 100, indicating it should never be shown in mapping."[1] The name 'Null' refers to the two 0 co-ordinates, both of which are sometimes known as null in mathematics.
Origin (mathematics) In a Cartesian coordinate system, the origin is the point where the axes of the system intersect.[1] The origin divides each of these axes into two halves, a positive and a negative semiaxis.[2] Points can then be located with reference to the origin by giving their numerical coordinatesâ€”that is, the positions of their projections along each axis, either in the positive or negative direction. The coordinates of the origin are always all zero, for example (0,0) in two dimensions and (0,0,0) in three.[1]
