map grid distances

Post by louiekidd »

I apologize if this has been posted already but I found nothing on the search of "grid distance".

Can I get a confirmed list of distances from the map grid to actually walking distance. I tried last night to estimate these numbers best I could by standing on a grid intersection and setting a move marker on each grid line to see how far it was, and the math was not adding up. These are the numbers I came up with.

facing cardinal direction:

Keypad 150 meters
Grid 500 meters

diagnally:

Keypad 240 meters
Grid 715 meters

The problem lies in the first 2 measurements. The grid is a 3x3 block of "numpads". But 3x150 is not 500... Yet when i set the marker in-game to 3 numpads due north of my position on a grid intersection, the measurement read just over 500 meters. Setting the marker one numpad away read in the ballpark of 150....how does this work? Can anyone provide a list of measurements that are true, because either my method is faulty or this game measures distance in a means i'm not aware of. I ask this favor as i'm miserably bad at estimating distance when trying to alert my team of targets, perhaps knowing what each numpad and grid square translated to in meters would be of great help as I can relate the enemies position to the map and call a distance accordingly using math and map grid squares.

Thanks :grin:

The grids are not the same size on all maps, they're 1/8 of the map's side length.

So for instance Korengal Valley is 1024 x 1024m, which means that one grid covers 128x128 m and each keypad within the grid covers 42,666666666666666666666666666667 m.

so what your saying is there's really no way of knowing unless you know the dimensions of the map itself

its pretty easy, since you can see the size of the map when you join, 2km, 4km etc.

divide by 8 for sector, devide that by 3 for keypad.

Just note that everything is binary so 1 Km is actually 1024m as said, 2 km is 2048m and 4km is 4096m .
