Hi Frank 

Good to read you again!  Thanks for the image (and text?) adjustments.  

About a possible missing node at intersection of ways 1 and 3, the model aims at sharing nodes when the ways are shared/overlapped.  In the example, way 1 and 3 are crossing each other, they don't overlap as for ways 2 and 3.

Hi Daniel,

Interesting text. Few comments:
* I've updated the image. The tags on ways 3 and 5 are not needed, since those are the outer ways of multipolygons. I also removed the JPEG artefacts (saved as PNG, etc.) and enhanced the color for wooded areas. By the way, shouldn't there be a node at the intersection of ways 1 and 3?
* I think it is possible to do imports in the fully integrated model as well. It isn't necessary to import everything at once, but it could be done in multiple iterations.
