[Talk-ca] JOSM Difference?

[Bégin, Daniel]

Hooo!

Actually it's a very simple process - we look only at geometries that are way apart (25 meters) from each other.  We then only get significant geometric differences.  We might eventually use a smaller value.  

So, No tag changes will be detected on short term. If we are able to detect/use a lot of improvements made by the community, we might developped a more accurate process that will enable tag changes detection.

Regards,

Daniel

Hey Daniel,

I am curious, how would we handle changes to existing roads?  Ie I imagine once the address data is added to Manitoba, that will also mean that the street names will be added.  Or would this be somewhat of a manual process?

Thanks,
Tyler
