Unmapped → It is formed from "un-" (meaning not) and "mapped" (from the root "map", which comes from Old French *mappe*, meaning a representation of an area). The word "unmapped" means not represented on a map or lacking a map representation.
Think of 'not' ('un-') having a 'map' — so 'unmapped' means there is no map representation.
