Gotcha. Sorry, I thought you were wanting to keep the data in the map and programmatically update it. <br><br> It's gonna be impossible to use the rollback script at this point, but since there are only nodes in the dataset the algorithem isn't that complex.<br>
<br>1 Query the changeset for all node IDs<br>2 Query the database for the version number of the resulting nodes<br>3 If version = 1, delete node else flag for user review<br><br>Of course since my C & bash skills are rusty as all get out and all my SQL experience is with mySQL (pun intended) I have no idea how much of a hit the server will take running step 2.<br>

I support the idea of deleting the data. Should I do it? Its there an<br>
easier way to delete a whole changeset?<br>
<br>
I am still working on the processing, and will continue on this<br>
outside of the OSM database.<br>
<br>
It my a mistake to just import the data,<br>
but as I said, I am willing to put the work into cleaning it up. I am<br>
commited to making sure that we have a solution to this.<br>
<br>
My internet was cut off for the past two days, when all the data is<br>
downloaded I will be able to tell you what is in the EPA dataset.<br>
<br>
I wont be importing it directly but setting up a database.<br>
<br>
Now, it should be easy enough, once the data is there, to also do<br>
checks and updates.<br>
>From a programming point of view, we should be able to tell if an ID<br>
has changed, and as long as the IDS are present to be able to update<br>
the data as needed in OSM.<br>
