Yes, I know that. I meant that it is coming from planet, not directly derived from the main database like osmarender. >> So perhaps use the planet diffs to determine areas which have changed >> and proactively mark all such areas dirty. > > The problem is how to merge planet diff into postgis , I think Jonb has > done some work/research in this area. > Are there existing tools (osmosis?) that given a planet diff would > return 'dirty' areas? Everything listed in a planet diff is by definition dirty, yes. I don't think you;d need to change the rendering process at all - keep on converting the full planet to database; just have a new means for marking dirty areas - derived from the lat/lons of all nodes in the planet diff corresponding to the current planet, plus the lat/lons of all nodes of all ways listed in the diff.
