It would probably take far too much CPU power to be worth running on the tile server.

You can convert non-round roundabouts to round ones by selecting them and pressing "T" in Potlatch.

Since they are a temporary feature, I would be inclined to not bother mapping them.

Looking at the GPS traces there the Yahoo imagery appears to be spot on.

Deleted. OSM is for real data only. Perhaps we should create an unstreetmap.org for fictitious data?

(This is almost certainly copyrighted as well.)

I noticed that the area near Pembroke, Ontario in the northeast of the province is not imported. Is this part of a Quebec tile?

This is the import of the GeoBase National Road Network. Please see osm.wiki/GeoBase_Import for details.

The names on every block are an artifact of the process by which the data was imported. Please do not combine ways to get rid of this as this will delete data which will allow future updates to be added to the GeoBase data. Hopefully a future version of the renderers will be intelligent enough to not show names on every block like this.

Streets from the GeoBase data are not automatically connected to the existing data. This has to be fixed manually - I can start on this if you tell me what area you would like fixed. It is probably easier to do this in JOSM. Furthermore, the data is likely to contain errors, and one way streets are missing.

For more information you should talk to stevens who is doing the bulk of the GeoBase import.

SPAM

Presumably they mean cycleways?

LOL OpenStreetMap does need to "infect" other parts of the world a little bit more.

Just a note of caution - keys and tags are case sensitive, they should not be capitalized. Thus please use "name", not "Name", otherwise your lovely hard work will not show up on the renderer. I have fixed this for now.

Press "c" to add a comment with Potlatch.

I've been tagging hydro corridors (that is the area with the power lines underneath, owned by the electric utility) in Toronto with landuse=grass, name=Hydro corridor. This is probably not the best tagging, but it will do.

The back button is broken. Can you fix it?

Mapnik takes a while to update. Have patience.

Next time, you should save more frequently while editing to avoid losing data.

This is actually MassGIS data, which is considerably more accurate than TIGER data, but still inaccurate in some places.

TIGER data has lots of non-existent roads like this, just delete them.

Yeah but at University of Toronto the profs seem to make everything due the week after reading week. So less mapping for me just as the weather gets better.

It's much easier to use JOSM in my view.
