When a formula is given and a value is missing it can be handy to see all possible options on the map. This tool shows all possible locations of incomplete coordinates.
Enter the coordinates and replace the missing value(s) by the characters a-z or a ?. The characters will be replaced by a number from 0-9 to obtain a valid coordinate. Different characters will be replaced separately, equal characters get equal values. Multiple question marks will always be treated as separate characters.
Click a marker to obtain the coordinates of that location and the value of the characters.
