Good job! I've heard some TW mappers discussed with the new Mapbox images.
Thank you!

Re: [Talk-TW] Working together in improving Taiwan roads

Hello everyone,

As discussed earlier by Maning [0], we reviewed alignment of current
OpenStreetMap data and imagery available for tracing with Strava GPS
traces.  I posted my observations in my diary [1].  As a result of our
review, our satellite team at Mapbox updated our imagery for several cities
in Taiwan [2].  All our Mapbox Satellite imagery is open for tracing in
OpenStreetMap.  We hope the community will find this useful in improving
the data.  This is just a start and we are excited to work together with
the TW-OSM community.
