Currently, we are surrounded by technology, and with a single click, we can find out the exact location where we are. This is possible thanks to a precise navigation system called GPS (Global Positioning System) which, through a network of 24 satellites and radio waves, can accurately determine where we are in real time. The position of an object, a target, or a reference point on the planet can be represented in several ways, the most well-known way is through the angular coordinate reference system, which is latitude and longitude. The geographic coordinate system (GCS) uses a sphere to define locations on Earth, using angles measured in degrees from the center of the Earth to any point on the surface. These coordinates can be found in several formats, depending on the way of writing, the classical representation of latitude and longitude is in degrees, minutes and seconds (DMS), but in everyday life, through navigation applications we find them in another form, that is degrees and decimal places (DD) or decimal degrees and minutes (DDM). The relationship between the three ways of writing coordinates is simple, and through a few calculations we can transform in minutes, even seconds from one format to the other.
