Elevation maybe?
Irrelevant if there are no island on the map (as in this case) situated in the water offshore. On shore maps do not have that requirement and don't have to because its is for navigation on shore. For navigation off shore and along a coast or approaching a coastline, marine maps have all islands and hence corresponds to your radar picture. Flying/relying on a route and checking it against not accurate maps is two big holes (giving false security) in this tragic accident.
When you are that low you need to fly and navigate like a boat to stay safe.
