Hi everyone,

Thank you for your warm welcome.  My replies inline.

> QA tool to fix small errors in Taiwan some times ago.

Yes, we do global fixing of common errors using to-fix.  We welcome
feedback if you notice any issues with our edits.

what the local community can do to help?

Making OSM navigable is our main goal. By navigation, we mean
navigation for car. Data such as:
- roads and names
- oneways
- traffic signals
- turn restrictions (including conditional turn restrictions)
- turn lanes (including bike lanes)
- speed limits
- exit signs and destinations for motorways


We have worked with the OSM community in several countries such as US
[0], Canada [1] and Germany [2] and we plan to do the same for other
countries.  While looking at the data in Taiwan, we noticed there were
misaligned roads [3], so before we add navigation specific data, its
important to first improve road geometry.

We will probably work on a per city basis.  Do you have any suggestion
of which city we should do first?
We are still continuing our research before we start mapping.   We
will definitely share the outcomes here.

We normally use the Tasking Manager to coordinate mapping, if the
community use other tools,
let us know so we can work together.

@rex,

I just joined slack.

This is amazing! I loaded the wtms in JOSM and the alignment from
STRAVA is really good [4]!
I assume the license to trace in OSM is OK?
We will use this as a reference for aligning instead of the really old Bing.
