Spring RTS Engine

I made a simple map nothing to special, but I am having a problem with classification. The map is two big land masses on each side of the map with a large ocean dividing it. There is no passage for movement of land based units from each land mass, but there is space for land battles if you had a couple hover transports ferrying troops.

So for the sake of compatibility with AI, what would I call this map? A pure water map, or a land water map? Currently it is a land water map, but NTAI trys to send tanks to the other side but the units end up just getting stuck on the coast.

NTai will have the ability to distinguish between landmasses in XE10, the basic framework for it is already half implemented in XE9
