2 years ago The best way to access underlying imagery is through the bing maps API (https://www.microsoft.com/en-us/maps/location-data). You can make a metadata request (https://docs.microsoft.com/en-us/bingmaps/rest-services/imagery/imagery-metadata) per tile and confirm the structure is within the vintage range.
Using QGIS to import Bing maps you can get aerial images, but this is not guaranteed to be the images corresponding to these annotation, which means some buildings may have been added or disappeared. I am not sure how to get the "Bing Maps imagery between 2014 and 2021 including Maxar and Airbus imagery", can you publish the corresponding aerial images? This will give a big boost to the task of semantic segmentation of buildings.
