I can convert pose or odom data to costmap(Occupancy Gird Map) index, with this i = (width * y) + x. I learned how to do so from here. Is there a way to get x and y from i? I know its two unknowns thats why Im trying to figure out if there is some way.

It’s possible to solve but you need to discard for complex solutions in your case.

Take a look at this: https://math.stackexchange.com/questi...

There are two unknowns, but you know width of costmap already.

x = i % width
y = (i - x) / width
