How can I convert coordinates of type N 0 W 0 to latitude and longitude?

  • 772

Maybe I didn't know how to search in English and that's why I decided to ask this question:

I have several coordinates of type:

N 7.45.05.34 WO 76.43.41.47

I need to convert them to coordinates like so:

7.888216596715097, -76.63187127560377

I am working with the API v3 for JavasCript for google maps, I am not attaching any code because I have not found anything concrete regarding whether this API allows this conversion or allows markers to be placed on a map by providing said coordinates.

javascript

    In the end it was something quite simple:

    1. I had to divide the coordinate into 3 numbers, which I did with the following script (taking into account that there were many coordinates)
    2. I had to do a basic operation which was:

      (((SECONDS / 60) + MINUTES / 60) + DEGREES)

    var log = console.log.bind(console);
const div = 60;
var coords = ['N 7.45.5.34 WO 76.43.41.47',
  'N 7.42.38.1 WO 76.44.14.5',
  'N 7.42.34.5  WO 76.45.3.4'
];

coords.forEach((coord, index) => {

  const split = coord.split("WO");
  if (split.length == 2) {
    split[0] = split[0].trim();
    split[0] = split[0].substr(2) + " | ";
    split[1] = split[1].trim();

    const current = split.join().replace(",", "");

    const secondSplit = current.split("|");

    if (secondSplit.length == 2) {

      secondSplit[0] = secondSplit[0].trim();
      var lat = secondSplit[0].split(".");
      if (lat.length == 4) {
        var superLat = " " + lat[0] + " " + lat[1] + " " + lat[2] + "." + lat[3] + " - ";
      }

      secondSplit[1] = secondSplit[1].trim();
      var lng = secondSplit[1].split(".");
      if (lng.length == 4) {
        var superLng = lng[0] + " " + lng[1] + " " + lng[2] + "." + lng[3];
      }

      const superCoord = superLat + superLng;
      const coordSplit = superCoord.split(" - ");
      const currentLat = coordSplit[0].trim();
      const currentLng = coordSplit[1].trim();
      const latSplit = currentLat.split(" ");
      const lngSplit = currentLng.split(" ");
      const finalLat = (((Math.round(parseInt(latSplit[2])) / div) + parseInt(latSplit[1])) / div) + parseInt(latSplit[0]);
      const finalLng = (((Math.round(parseInt(lngSplit[2])) / div) + parseInt(lngSplit[1])) / div) + parseInt(lngSplit[0]);

      log(superCoord + " = " + finalLat + ", " + finalLng)
    }

  }

})
