Given the discussion of NHD imports last week and my attempts to make
the NHD data more manageable, it would be useful to know where the
failure points are.
Since JOSM was used in this case, I already know one problem from
experience - if you upload from JOSM and the upload fails, you end up
with a partial upload. Recovery is ugly - a full revert of the
changeset or a manual match against the changeset to figure out what was
uploaded.
Even the better bulk upload scripts that create a checkpoint file
every N data points have a problem with the last chunk because they may
think the upload failed, but it actually succeeded. That requires a
manual fix, or perhaps an automated version could query the last
changeset to figure out exactly what was uploaded, and continue from there.
