Why, the land is used to grow grass. Thus, landuse=grass.

That depends on observation time. E.g. much of Europe is covered by fog in
Autumn. So this will be landcover=fog.

It also depend on the observation point. When you see arial images, forests
appear to be covered by trees. But when you are inside a forest, you see
more herbaceous plants than trees.

So go on and define these implications in your proposal. Currently, no
implications exist.
