This has been my general rule of thumb (libraries differ constantly what they consider NE, N, NW to be for certain cities). Often NE just means "near or also in belgium" too. Obviously its not technically correct, but france is a weird shape.
EDIT: put a new map up, i drew the last one wrong lol. Cambrai is basically my border for N and NE france.
