As to whether the D80 or D200 is better for the OP's needs, I can't say.
The D70 and D80 are definitely different generations. The D80 inherited a large portion of it design and electronics from the D200. Its kind of a D200 light (literally, and spec-wise). The D80 is a significant improvement over the D70(s), but is not as good as the D200. Still, I'm not sure if the features of the D200 are worth the extra weight, size, and expense.
Part of it might depend how the OP will use the camera on land.
