<br>
</span>Will you edit the whole state?<br>
Do you really need to have all of it?<br>
<br>
Editing large areas and a lot of objects isn't usually the best thing<br>
to do: it can cause duplicate data in OSM and/or you will hit a lot of<br>
conflicts.<br>
<br>
overpass is the easiest way to get fresh data, but you need to filter<br>
a smaller region or some specific data that you want.<br>
