Hi everyone, Thanks for the note, I created task 2102 and also provided the additional imagery service. Unfortunately certain areas of the custom image service are offset from Bing and existing OSM data. For this reason I purposely didn't load the custom service into the task, but offered it in the instructions to supplement clouds, etc. These tasks are designed to get new mappers involved with OSM. Offset imagery significantly raises the bar of entry and can introduce data quality issues.
I've since noticed areas with significant change (buildings, trees, etc.) between the two images. The service I provided is several years newer than Bing. This highlights one major challenge with introducing new imagery in OSM. It would be great if traced features were automatically tagged with the date/year of the service used. Before creating a custom service I check Bing for date/year, cloud cover, and quality. If Mapbox isn't a good supplement then I search for other scenes from the DG archive, and do my best to find a recent cloud free scene that aligns with Bing. I'm open to suggestions on the best way to proceed.
