Have been thinking about solving the problem where a zoom level 12 tile is completely enclosed within a large landuse=forest area. Currently, the forest is not renderered. Interested in ideas to approach this. 

So far I have come up with:

1. Use a relation type=enclosed to connect any node or way within  the tile (role=within) to the enclosing landuse (role=enclosing). Change the data download to download the enclosing landuse whenever the enclosed relation is downloaded.

Pros: Simple, easy to implement. Good for smaller enclosing areas. Can be maintained using JOSM
Cons: Will be clumsy for large enclosing forests. 

2. Expand the current oceantiles process from just water/land to include other landuse types using other colors as needed.

Pros: Easier to maintain (for people who can cope with png2tileinfo)
Cons: Hard to maintain (for people who cannot cope with png2tileinfo). More work to implement.


Comments appreciated.

Regards,
Brent.
