Usage

[latDec, lonDec] = dms2dec(String lat, String latRef, String lon, String lonRef);

Params

• lat – latitude in "degrees, minutes, seconds" format
• lagRef – latitude hemisphere reference (N or S)
• lon – longitude in "degrees, minutes, seconds" format
• lonRef – longitude hemisphere reference (E or W)

Return

• latDec – latitude converted into decimal format
• lonDec – longitude converted into decimal format

Parse dms strings

var dec = dms2dec("60/1, 21/1, 4045/100", "N", "5/1, 22/1, 1555/100", "E");
// dec[0] == 60.36123611111111, dec[1] == 5.370986111111111

Parse dms arrays

var dec = dms2dec(["60/1", "21/1", "4045/100"], "N", ["5/1", "22/1", "1555/100"], "E");
// dec[0] == 60.36123611111111, dec[1] == 5.370986111111111

dms arrays as decimal

var dec = dms2dec([60, 21, 40.45], "N", [5, 22, 15.55], "E");
// dec[0] == 60.36123611111111, dec[1] == 5.370986111111111

GeoJSON

NB! Remember that GeoJSON stores coordinates in reversed order (longitude, latitude) which means you have to reverse the order of the coordinates returned from dms2dec().

var geojson = {
  type: 'Point',
  coordinates: dms2dec(lat, latRef, lon, lonRef).reverse()
};
