[Talk-ca] Deleted nodes.

[Frank Steggink]

Hi Michael,

You might want to look at upload.py [1]. This is a family of scripts 
related to OSM uploads and other processing. One of the benefits is that 
with it you can "sort" the data, so that ways and relations are uploaded 
immediately after the nodes are uploaded. This will prevent large 
amounts of unconnected nodes. As you know, JOSM first uploads all nodes, 
then all ways, and only then the relations.

If only nodes are missing, then you could try to upload another time. If 
you've already ended up with duplicate ways, etc. then you can try to 
see if they are cleaned up by validating the area in JOSM, select 
"Duplicate ways" in the Errors branch, then then fix. For some reason 
this doesn't work all the time...

Regarding those edits from magellan and the like, I've been hit with 
them sometimes as well (not with Canvec, but with 3dShapes in the 
Netherlands). It is very annoying. Just send them a PM that they should 
not clean up recent data, say anything which was uploaded less than a 
few days ago.

HTH,

Frank
