Random coordinates are given in the table, and that values are used to represent those coordinates.
The world is separate from a bunch of numbers. We call them coordinates. Every point in the word has coordinates.
Of course, all these are just numbers. There are still unexplored places in the world. However, having untouched areas does not mean that there are no coordinates.
To use this tool, just click the purple button. Each time you click on the purple button, a new coordinate will appear.
