As you already stated in your comment, these are coordinates from a NOTAM (Notice To Airmen). The values are already in degree, minute and seconds using the format DDMMSSNDDDMMSSE or DDMMNDDDMME.

See also the following examples:

472027N0114441E --> 47°20'27''N 011°44'41''E

In case the seconds are zero, these are ommitted from the notation:

4729N00937E --> 47°29'00''N 009°37'00''E

  • These are the standard format for NOTAM ? is there any other format available or only this 2 format are used? Sep 8 '17 at 12:23
  • There is also the possibility to have only one coordinate with a radius (in nautical miles). And it's also not necessary that a NOTAM has extra coordinates at all mentioned, in case e.g. a whole flight information region (FIR) or airport is affected. However I am no expert in this topic, so you might get a more profound answer over at aviation.stackexchange.com regarding this new question. Sep 8 '17 at 12:51
