Latitude e Longitude

Definição

Latitude e longitude formam um sistema de coordenadas geográficas que usa graus angulares para identificar unicamente qualquer ponto na superfície terrestre, com latitude variando ±90° e longitude ±180°.

Explicação

Latitude measures distance north or south of the equator (0°), while longitude measures east or west of the Prime Meridian through Greenwich, England. One degree of latitude equals approximately 111 km regardless of position, but one degree of longitude shrinks to zero at the poles. GPS satellites rely entirely on this system to provide positioning accurate to within a few meters.
