How to convert lat longs into degree format for Go

问题:

I have lat/long coordinates for a list of ports. The coordinates are in a 2856N 05211E format (totally made those numbers up, btw). I'm trying to figure out how I can convert them to the degree format the Google Earth pluginuses in order to plot them on a map. Is there a parameter in the API that I could use to convert this? Any ideas would be appreciated.

I'm assuming you can parse the values yourself. If not, then provide the language you wish to use.

The conversion is simple, Degrees/Min/Sec(DMS) to Decimal Degrees is

result = D + M/60 + S/3600;

If S or W,

result *= -1;

As always, do your own error checking.

-90 <= lat <= 90

-180 <= lon <= 180
