This is often why true to life maps that represent a real area on a 1:1 scale often need to make sacrifices and add elements into the map that are not there in real life because the odds of having a farm store, at least one grain depot and a BGA all within 2KM of each other that includes farmland is going to be rather rare.
A standard giants map is setup to represent a 2KM x 2KM square of land area. But now I think it is an attempted shorthand of the overall width and height of a map. I thought this was the case because modern Giants maps where twice as large as maybe the first Giants maps back in FS09 or FS11 or FS13 days. Folks, including myself from time to time have refereed to base Giants maps as 2X. 2X would be twice as big as something, 4X would be 4 times as big as something, etc. The X would typically represent that the map is a multiple of something else. We have issues with folks refer to map sizes with things like 2X, or 4X or 16X or 64X.
During my live streams of the 16X Nowhere Kansas map size came up alot so I want to interject a few general observations.
