How old were the old tiles? :-) I admit, I haven't posted any updates since September. However, I just finished processing the December 16th snapshot of the OpenStreetMap database and will be posting that to my website tonight.
They were the ones from September. I'm an OSM contributor so I like to be able to see my contributions (fixes and such) a lot sooner than a few months. :)
Your comment about old tiles getting flushed is unfortunately a design feature of the YAAC OSM preprocessing importer code. It replaces any 1x1-degree square tile with the new data for that tile in the input .pbf or .osm.bz2 file.
Hmmm... Yeah, I can see what's going on there. So I should be downloading more data than I am instead of trying to stitch together smaller pieces.
This is why I routinely import the whole planet dataset in one giant lump. The last run took me not quite 22 hours to process (on a fairly high-powered gaming system), and will take another hour to compress the individual tile files for more efficient network transfer for other users.
I always wondered how long it would take to process the entire globe's worth of data. I wonder if you were to process the daily diffs if it would take a vastly shorter amount of time and could keep the tiles up to date for everyone.
