Such a dirty-tiles list could be used in tile-expiring on the render servers as well. The current solutions to this have the same problem as the history tab: a change to the german border triggers the whole german country to be marked as dirty, because they're inside of the relations. Such an algorithem would be very useful on all rendering stacks -- and it's also a not so easy task (because of various reasons that don't need to be mentioned here ;) Peter _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
