Just one example of how out of date Bing imagery is. This is an area near the town of Mwinilunga in Zambia that is fairly remote. The development that was originally mapped as part of the #hotosm-project-13416 #zambia-census in 2022 used Maxar imagery (my thoughts on the effectiveness of this project are for another discussion). A HOT validator with any sense would not remove this but it would not be so obvious where there were buildings mapped in a remote village where a number of new huts and houses were added based on the Maxar imagery that do not appear in Bing imagery. The basis of this project is to map remote human settlements in Zambia, I assume to assist with the census that took place last year.
Had to add comparison as single image as I can not embed more than one image and can only reply 3 times.
