Degrees, minutes, seconds (sexagesimal) to decimal GPS positions. Useful for
parsing PGS exif tags in geotagged images.

Install

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

`javascript
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

// without spaces or commas in the dms strings are also supported
var dec = dms2dec("60/1,21/1,4045/100", "N", "5/1,22/1,1555/100", "E");
var dec = dms2dec("60/1 21/1 4045/100", "N", "5/1 22/1 1555/100", "E");
`

$3

`javascript
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

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

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()
};
