</div>Basically, the Augmented Diffs comprise exactly that information.<br>

They carry for each changed object the geometry information, either directly<br>
or by referencing the also in the file contained nodes. From that it should<br>
not be too hard to mark affected tiles as dirty.<br>

I'd suggest the id-sorted variant with info=yes. It is bigger, but the nodes<br>
are required to get the geometry for relations right.</blockquote><div><br></div><div style>I'm looking at the augmented diffs stuff but the documentation [0] appears to be stale.
