If access is set to allow you to add your map, yes - but you won't be able to tell your maps from other maps, other than it's the last one added. It won't give you an exact location and only shows a location at all if you have read the map. Davies Locker doesn't decode maps. It shows approximate co-ordinates for maps that have been read, to characters who have the skill to read them.
As an example, if I check my Davies Locker with my tamer it shows decoded and not decoded maps, but no co-ordinates, because she didn't, and can't read them.
