HI<br>
<br>
Currently I'm working on importing the Canvec tiles that make up Lac<br>
Seul in NW Ontario into OSM. Importing the data as it is, split into<br>
tiles and subtiles, is poor practice, and manually merging is time<br>
consuming and dull. So I began using JOSM's Join Overlapping Areas<br>
feature. This tool however requires that all ways be complete before<br>
merging. Resulting is a 100 000 node area that far exceeds JOSMs import<br>
limit and is time consuming to split up, and slows down JOSM. Is there<br>
an faster way to split this?<br>
<br>
