Theory !:Any point we want to find on the Earth’s surface can be located where a parallel (latitude) and a meridian (longitud) intersect. Latitude and longitud are the geographic coordinates.

What’s latitude? The angular distance between any point on the Earth’surface and the Equator. Measured in degrees north to south. Values between 0 and 90º

What’s longitude? Angular distance between any point and the Prime meridian/Greewich. Measured in degrees east or west. Values between 0 and 180º.
