It's a function to split the coordinates to some small blocks. For example, some country has a coordinates of north-east and south-west, two diagonals.
If I set the interval to 0.05, it will returns all the coordinates with interval of 0.05(or some value very close)
Note: you could regard the blocks as square, and the length of it's edge is 'interval'
So for these function, how to simpfy it and make it more readable ?
