Is there a standard? Cause people seem to take the top left corner when referring to the map.. Personally I've always done it bottom left corner, because that's how you normally read AFs =P But that would mean revamping the grid, because the devs didn't plop in an extra easting/northing.

 

Perhaps we should agree to a standard..

I take it from the number that is in the square, and the letter that is in the square. Then cut that square into sections on your numpad.

 

ie A8 = the sqaure with SW in it. Then the top right corner of that square = A8-ref 9.

 

Bottom right corner = A8-ref 3, Middle right side = A8-ref 6. And so on.

Yeah the numeric keypad refence point makes sense so crash site would be E3 pos 4.5 hahaha

I never got the numeric pad ref thing, someone care to explain it to me?

Like regular grid references, except the extra grid divisions (dividing the area referenced even more) into a 3x3 grid denoted by the keypad. ie. keypad 5 is dead centre of the area reference.

 

Anyway my original question was that do people take top left or bottom left? Seems like top left.

I'd say top left chuc...cos thats where A meets 1....

a is first letter o the alphabet,1is.......etc.

so most peps start there i suppose

use the number/letter within the square, because that is the way the map is designed, otherwise the square with SW in it would not have an index and also the 1 in the square with NW in it (image is cut off) would not have a purpose.

 

Cartography 101:

 

British (Australian) cartography uses numbers for both axis starting with the 1 in the bottom left. The index increases as you move up the y and across the x, the numbers are also located ON the grid lines throughout the map (not only on the edges).

 

The grid reference (GR) is the easting plus the northing.

 

The easting is the index of the line on the left border of the square, the northing is the index of the line on bottom of the square. Eg. The square with the left border indexed 13 and the bottom border indexed 47 would be GR 1347.

 

To be more precise that square can then be broken up into smaller squares by drawing (or imagining) another grid, numbered from 0 to 9 left to right, bottom to top, inside the square you are looking at (1347). Do the same as above get the easting and northing for this new sub-square and then add these numbers to you existing easting and northing.

 

This results in a six figure GR. Eg. If the area you want is in the sub-square bordered on the left by 4 and bordered on the bottom by 8 then you add the 4 to the easting (13) you already have, and the 8 to the northing (47) you already have, and you are looking at GR 134478.

 

This process can be replicate over again and again to be as precise as you like. GPS systems are capable of 10 digit grid references placing your location within a 1 meter square.

 

 

The American system seems to use letters for the x axis and numbers for the y axis. The numbers start from the top left and increase as they progress down and the letters start from the top left and advance as they progress to the right. The numbers and letters are located BETWEEN the grid lines and only on the edges of the map.

 

The Grid reference is the letter of the square plus the number of the square.

Eg. The square that lines up with F at the top or bottom and 7 on the left or right hand side is GR F7.

 

To indicate a more precise area this square is broken up into a new set of squares labeled again with numbers on the y axis and letters on the x axis. The new GR is the initial letter plus the new letter (usually in lowercase), Combined with the initial number plus the new number. Eg. make a sub-grid inside F7 and locate J2 within this sub-grid. This would be GR Fj72.

 

And so on...

 

Probably not really that useful to you, but that's why those maps don't make any sense to us Australians who use the good old metric system.

Just remember if you use the Numpad thing to say:

 

"GR F5 Key 5" or

"GR F5 Num 5" or something similar.

 

Hate people who say,

"GR F55"

Where the hell is F55????

Yeah thanks anyway lucid but i figured it out like 5 secs after my post.

if there is something on g5,for example g5 "top of square on left"

 

Just go g5/7....quick,easy and SIMPLE.

 

 

/ is your friend:)

This stuff works great on kashan if you have a heli crew that know's what they're doing. Just call out the rough position of the tank via grid and num ref and you're almost guaranteed it's death. Unless of course there is nearby AA, then you have to deal with it yourself.

Ah thanks Captain, that's the exactly answer I was looking for.. Damn yanks.

I was wondering what the numbers people were using inside the grid squares. I assumed it was a clock ref, grid co-ord then an o'clock for direction from centre of grid quoted. No thinking needed as long as u can read analog clocks.

Yeah keypad ref works well, had some good results on Kashan calling in the chopper.

 

Beats trying to ninjaneer them without any cover. Can take 10 mins to flank their position to drop a mine, only to be shot.
