[07:28] <icez> hey jcoxon
[07:29] <jcoxon> morning icez
[07:29] <icez> must be early over there?
[07:30] <defy> hey guys, do either of you know what format the long/lat is in an nmea sentance?
[07:31] <defy> I'm trying to convert it to decimal but not having any luck
[07:32] <icez> do you have an example?
[07:32] <defy> yea
[07:32] <defy> $GPRMC,033945.00,A,3647.32890,S,17440.90215,E,0.003,,310506,,,A*68^M
[07:32] <icez> eh
[07:33] <icez> could those be minutes or hours?
[07:33] <icez> uhm
[07:33] <icez> not hours;p
[07:33] <defy> well i thought it was DEG MIN.SEC, and tried applying the correct math to convert it
[07:33] <defy> but I end up about 500 meters off where i should be
[07:34] <icez> maybe its 3647.32890 minutes from 0 being Greenwich
[07:34] <icez> eh
[07:34] <icez> i mean from the equator..
[07:34] <defy> 3647.32890 should be about -36.788865 in decimal
[07:35] <icez> i get 60.78
[07:35] <defy> but i get -36.792034, so I was wondering if anyone knew of a different way to do the convert
[07:35] <icez> mmm that wouldnt work
[07:35] <icez> 60.78 hours is more than 24:/
[07:36] <icez> 1.013 hours if they are seconds
[07:36] <icez> :/
[07:38] <jcoxon> i'm not sure
[07:38] <jcoxon> brain really isn't in gear
[07:38] <defy> hehe
[07:39] <icez> Latitude 4250.5589 ddmm.mmmm
[07:39] <jcoxon> got an exam in a bit
[07:39] <icez> ddmm.mmmmm
[07:39] <icez> 42 degs 50 mins
[07:39] <icez> http://www.commlinx.com.au/NMEA_sentences.htm
[07:41] <jcoxon> right off to revise for me exam
[07:41] <jcoxon> see you all later

[07:42] <icez> defy, does that sound good?
[07:42] <defy> well I'm trying to convert to decimal
[07:42] <icez> uhm
[07:42] <defy> my decimal lat location is -36.788865
[07:42] <icez> is that even possible, to convert degrees to decimal?
[07:42] <icez> :P
[07:43] <defy> yea has to be otherwise gps wouldn't work
[07:43] <icez> like radiants?
[07:43] <defy> shrug
[07:43] <icez> i just dont see how you get a negative
[07:43] <icez> :/
[07:43] <icez> unless your lat is negative..
[07:43] <defy> I'm trying to convert to the format which google earth uses
[07:43] <defy> I assume thats just called decimal
[07:44] <icez> ohh
[07:44] <defy> negative is because i'm south
[07:44] <icez> well
[07:44] <icez> those are
[07:44] <icez> dd + (mm/60) + (ss/3600)
[07:45] <defy> hrm, I was deviding the seconds by 60 also
[07:45] <icez> oh;)
[07:47] <icez> well
[07:47] <icez> i'm gonna go to sleep before it gets to tomorrow
