What do you call a map coordinate or 2D array index pair?

I'm looking for a better name than the lengthy "coordinate" to use when dealing with 2D arrays and the composite of the indices like so:

 public class Map
 {
     public int x; // x coordinate
     public int y; // y coordinate
 
     byte[,] data;
 
     public static Vector2 CoordinateToWorldPosition(IntVector2 mapCoordinate)
     {
         return Vector3.zero;
     }
 
     public static IntVector2 WorldPositionToCoordinate(Vector2 worldPosition)
     {
         return new IntVector2();
     }
 }

I basically only need this when returning both indices from a function at once, but that made me think that my naming is not yet perfect.
