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.
