GPS co-ordinates

[simisteven]

I have picked up way points off Sealine, see sample below, but I am not sure in exactly what format these GPS points are represented ie. decimal, deg,min,sec etc and I cannot seem to enter them, as such, into Google maps.
can some bright chap please enlighten me.
Thanks

CONTAINERS - 5kms. NE of the harbour mouth in about 22m of water - very popular spot for boats going north as it is en route, also very close to NO1 (2.5kms). All baits(shad,mackrel,mozzies,sea pike), but generally very good for mackrel if they are about.

S 29 49 470

E 31 04 535



DOZER - 3kms NEE of the containers in about 26m of water, said to be 1 or 2 bulldozers washed off ship?? - not too popular as its a bit out of the way, decent bait and also some couta when targeted as well as daga in winter - good spot to balloon a mackrel for YFT.

S 29 48 523

E 31 06 000



BARGE (Virginia Barge/ T Barge)- 9kms. NNE of the harbour mouth, 2kms off shore in front of Virginia Airfield in about 23m of water - purpose sunk concrete barge to create AR(1990's) - also popular - all baits and also good to power drift over/around with baits for gamefish(if not too many boats) frequented by some good queenfish March-May(can get double figures!!)

E 31 04 500

Hey Simi, good to hear you're still in the game!
Without knowing those marks specifically, it would be safe to say its deg, min, & thousands of min. this is also the most commonly used format in our circles.

Definitely not decimal which is which is degrees, comma, to quite a few dec places.
confusion comes in when you have a mark written like yours but ending in 2 digits instead of 3 because it can then mean either deg min sec or deg, min, min to 2 decimal places.

Not sure what format your mapping program uses but once you've inputted the mark into your gps you can go to your global settings and convert your marks to whatever format you need to to be able to input them to your mapping program, then just change the format your gps displays in back to the usual.

hope this helps, regards F

Simi once you have Google earth opened go to - Tools - Options & look at the 3D tab . On the " Show Lat/Long " tab you have 4 choices of co ord format , the second option of degrees  , minutes & seconds is probably the most widely used  . If someone has given you a different format you have the option of matching the format given in Google Earth.....

Thanks for all the assistance on GPS interpretation chaps, much appreciated.
I have, in the meantime. resorted to dropping white buckets with a mark on it, and anchoring it to the bottom with a stone. So if you all see white buckets floating out there, they're mine!
Thanks again!
