Re: [Talk-ca] CANVEC Comments
Found it in JOSM, you have to select the nodes then split way is available at the top of the tools menu.

Re: [Talk-ca] CANVEC Comments
I'm feeling thick today. How do I break it into ways? This isn't my top priority at the moment I'm busy putting names on unnamed streets.

Re: [Talk-ca] CANVEC Comments
With both halfes of the building polygons loaded into osm, break apart both polygons into ways, and remove both of the ways that are in the middle of the polygon, then merge the ways back into a closed polygon, it might require reversing the direction of one of the ways. this retains the geogetry and merges the 2 adjacent polygons into one. cheers, sam On 7/30/10, john whelan wrote: > Well I now know a little more about JOSM and Validator but I still > haven't quite worked out how to merge the two parts of the building. > > Thanks John > > On 29 July 2010 21:35, Tyler Gunn wrote: >> If you draw a selection box over where the two tiles meet and run the >> validator in Josm one of the errors it can report is "duplicate nodes". >> When you are merging tiles where roads and areas are split between the >> tiles there is a copy of all nodes on the "border" between the tiles in >> each file.

Well I now know a little more about JOSM and Validator but I still haven't quite worked out how to merge the two parts of the building.

Re: [Talk-ca] CANVEC Comments
If you draw a selection box over where the two tiles meet and run the validator in Josm one of the errors it can report is "duplicate nodes". When you are merging tiles where roads and areas are split between the tiles there is a copy of all nodes on the "border" between the tiles in each file. Josm Recognizes this and can merge the nodes from both tiles so there are no duplicates.

Sounds simple but Shift-J doesn't seem to do anything, they don't quite overlap. What is a duplicate node error and how do I fix it?

Re: [Talk-ca] CANVEC Comments
Hi John, With respect to buildings being split, perhaps it would make sense to regenerate .osm using larger tiles (or even generate .osm for whole provinces?) It's easy enough to split them with osmosis at home if needed. As for hand-drawn vs imported, it's a sensitive topic; there's a danger of starting a holy war:) I for one agree with you, geobase/canvec is topologically correct and is pretty much ready to use. I'd say, if you're local to the area, just do what you think is best. If you do delete exising roads in favor of canvec, please check if someone has added oneway= tags or some other potentially useful tags (find in Josm works well) and transfer them to new streets.

The best way to accomplish this: - Select the data all along the boundaries of the tile. - Use the JOSM Validator on the selection. - Fix all the duplicate node errors. - Select both ways that make up the building/area (ie shift-click on both parts of the building) and hit SHIFT-J to execute the "Join overlapping areas" - Voila! > What I find frustrating is the CANVEC data for roads appears to be > almost spot on.

I hear you; Winnipeg's road network was hand-drawn by someone in Potlatch, and there are a LOT OF places where roads overlap but don't connect, etc. The Canvec data is definitely higher quality in that regard. It's this manual merging headache that made me more to rural MB for a little while. Lol, it's easy to add in the Canvec data when there is no data there already. :) Tyler -- -- Tyler Gunn ty...@egunn.com ___ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
[Talk-ca] CANVEC Comments
The new Canvec tiles are very good quality wise. However when a building or park is on two tiles it would be nice to combine the two parts so it gets one name etc. Has anyone worked out how to do this in JOSM? I use http://keepright.ipax.at to clean up Ottawa's existing roads and I've spent many many hours connecting street junctions and floating islands but I know I still have many more hours of manual clean up ahead of me. What I find the most difficult are the streets that have been wrongly named. Street qualifiers are the normal source but a few times now I've come across three streets merged into one and given a single name. Very difficult to pick out and correct. The numerous streets with no name are easier to fix and the easiest source to use for this is the CANVEC data. What I find frustrating is the CANVEC data for roads appears to be almost spot on. I've come across two minor places where it doesn't include a new road or part of an existing dirt track but if we were to totally replace the existing road network in Ottawa with the CANVEC data the quality of the map would be much higher plus you could then run routing software on it and it would save me a fair amount of clean up effort. Most of the value add in OSM comes from POIs that are not part of the road network so that value would remain.
