Lat & Long

Hi all,

Am entering marks on new plotter and cant remember where the zero goes if you end with two numbers.

ie 001,241.023 or is it 001.241.230. 

 

Many thanks,Mick.

If it's .45 the 0 goes after.

ie. .450

[Brian]

In reality it's been rounded to 2 decimal places.

So could be anywhere between .446 and .454

[Brian]

Can't have 241 minutes. Must be less than 60.

It depends what setting you have selected in the plotter

 

I believe that it is degrees, minutes decimal

 

It also needs to be told if it is North/South and East/West

 

IE;

001 degrees 24 minutes decimal 023 west becomes

001,24.023W

 

an example

DOLPH 3 Tope & Rays - C/Church 50°40.539N  001°37.756W 

 

Hope that helps

Thanks for replies, but not sure this answers question .

What I mean is if the decimal no is only two numbers and my plotter needs three do I put a zero in front or after two numbers.

ie; S/bourne rough N50.40.87 W01.47.91. so as my plotter has space for 3 nos would it be N050.040.087 W001.047.091.

Cheers Mick.

As I said. You put the extra 0 after.

So N50.40.87 W01.47.91

Becomes

N50 40.870. W01 47.910

 

N50 = 50 degrees

40 = 40 minutes

.87 is decimal minutes

So 40.87 is the same as 40.870

 

E.g.. 1/2 = .5 = .50 = .500 = .50000000

Just spent 1 1/2 hrs on boat changing lat & long so 0 in right place. Made a difference to the position of my marks   .

now I just need someone to go and tell the fish to be there.
