I was reading a Digimon novel, but I have problems with this sentence.

>
> デジタルワールドにも東西南北という方向性が存在する。地球上の四方は人間が生活するために便宜上その概念を使用しているものだが、デジタルワールドではその世界が成り立つ時に東西南北を起点としたグリッドを使用していたのかもしれない。

I don't understand what the second sentence says, but I think it is something
like: "at first, the four cardinal points were a great place to live in, but
then it was divided into different areas.

A problem with this sentence 地球上の四方は人間が生活するために便宜上その概念を使用しているものだが、デジタルワールドではその世界が成り立つ時に東西南北を起点としたグリッドを使用していたのかもしれない。
**_In the Digital World also, there are all four points of the compass, north,
south, east and west._**

**_In the earth, in our actual world on the surface of the globe, (there are
no such points actually, but) we use them for the convenience for humans to
live on._**

**_In the Digital World, however, the grid that starts from north, south, east
and west might have been settled in advance when the world was created._**

In my opinion, the latter part of the sentence was not well written in
Japanese. So there is no wonder for Japanese learners to have difficulty to
understand it. I don't like the sentence because it seems illogical from a
scientific viewpoint. But I can understand what the writer was trying to say.
