8 Digit coordinates

[Pteradon]

Hello,


This isn't an addon request.
I'm just curious why Arma2 use only 6 digits coördinates.

When i was in the army, we used only 8 digits coordinates + 2 letters for
pointing wich section of the map.
Correct me if i'm wrong, i thought this is standard for NATO troops.

example: AJ 2145 3857

A 6 digit coördinate is to 100 meter accurate,
an 8 digit coördinate is accurate to 10 meter.

For reading the coördinates on the map, we used this tool;


Im curious why this isn't used in Arma2?

Maybe because another system is used? If you have mouth full of orange you can't put apple in there. One system that works is enough and efficient

because its too hard.


standard 1:50000 scale maps have 4 digit grids, and any more than that is on the human to add in (6 to 8 to 10 ect). wile easy for anyone who has had some training in maps, it is a bit more difficult for others (especially if there were no ingame tutorials)

Its possible that if BIS used a 4 digit grid coordinate then they would have to add in multiple letter coordinate zones (AA zone, AB zone ECT). by having a 6 digit they avoid it and keep it accessibly simpler.

also then people would complain on how the letter coords were not realistic as they did not comply with real world terrain data

edit: also, im not to down with figuring out scale on maps, so what scale is there chernarus map? 1:10000? 1:25000? 1:50000?

Most (milsim) units/squads you will find operate with 8 digit coordinates. Only that they have to be guessed.
This was very handy because in ArmA 1 the 6 digit grids used to be 200m by 200m which is very big for a landing point or impact grid

But i know NouberNou is working on a compass, it's maybe even the one you've shown. You can see it for a few frames in this vid at 0:05

I think it's a map config entry that sets it. As far as I can remember, you can specify an 8-digit system in the config if you wish.

Actually a six digit coördinate is precise up to 10 meters, while an 8 digit coördinate is precise to a meter.
It's not useful for most civilians to use an 8-digit coördinate, since most already struggle with a 6 digit coördinate.
The 8 digit coördinate is used mostly for precision bombing, but for infantry to find a location a 6 digit coördinate is more then adequate.

This is completely wrong, as the OP said a 6 figure grid is a 100m x 100m square. 8 figure being a 10m x 10m square (Refrence). Also for "infantry" a 6 figure is not adequate. A 6 figure (100m x 100m) is 10 000 square meters of real estate, because of the inherit inaccuracy it is rarely used unless indicating a very general area. 8 figure, as the OP stated, is generaly standard within militarys with 10 figure becoming more common as it's the standard readout on most GPS.

It will depends on wich scale map its used, i think

The digit coördinate is not only for precision bombing, but also for artillery.
I have use it irl as an recce, for getting mortar support.

As an recce we had to make contact reports with 8 digit coördinates.
The better the contact report is, and the contact location, the better view the overwatch commanders have of the situation.



I was just curious about it, because most of Arma2 players like to play at an high level of realism

You're all sorts of jacked up. If you are using MGRS with the typical 1:50000 scale, 6 digits is within 100 meters, 8 digits within 10, and 10 digits within 1 meter. I think you are trying to multiply those numbers (IE 100 times 100 equals 10,000). When instead you should be seeing it as its 100 meters long, and 100 meters wide, giving you a 100 meter radius around where you want to be.

Nope, you're wrong. A square with a side length of 100 meters is in fact 10,000 m² big. Might not look like a huge area on a flat field, but as soon as it's in an urban area, it's too large to be of any real use.
