[Talk-ca] Canvec.osm samples

Wed May 5 21:44:32 BST 2010

Thanks Adam,

obviously it seems there being bad tags in the samples.  I'll replace the samples. 

About the conversion script, it should be OK because I have succesfully created/uploaded many tiles since then using JOSM.

Got a response on the error here [http://josm.openstreetmap.de/ticket/4971]. Turns out there is a malformed tag, that doesn't have key or value in it (a null tag)
Here's line 16220 (the offending tag):
<tag/>
To compare, here's line 16221 (a properly formed tag):
<tag k="waterway" v="stream"/>

The josm developer has put in a better error message regarding what the problem is, but josm still will not load the file.

So does this come down to there being a bad tag in the original Canvec data, or does the conversion script need some modifying?

	Ideas:
	-mention this on the irc #osm-dev chat. As a JOSM develepor might be
	able to help further
	-zipping : try .bz2 compression, instead of regular zip, maybe it does
	something different to the .osm data?
	-at that same time (with that new josm revision, WMS didnt work for some people)
	-josm doesnt automatically update all the plugins, when you get a new
	version of the main exe file,
	-Osmosis is the tool to combine .osm files, i havent yet been
	sucessful at merging them (on the command line)
	-each node would need a new ID, when merging files, maybe there is a
	max # of features?
	-Also, i'll check with user:MikeyCarter as he has gone ahead and
	converted canvec for the Barrie Ontario area, using a customized
	method.

	Cheers,
