Incomplete Coordinate Calculator

Replace missing coordinate digits and map every valid possibility.

Replace missing digits with a unique letter such as A, B, C or with ?, and this tool will calculate all valid locations. Supports up to 3 substitution variables. DDM format only, for example N12 34.A67 W089 1B.3C4. Capital N, E, S, and W are ignored as substitution options.

When enabled, A=1, B=2, C=3 is allowed, but A=1, B=1 is not.
