The basemap imagery comes from a variety of sources at a range of resolutions—in all, over 80 different versions of the basemap are available. This is useful because when you view imagery basemaps, you typically only see the most recent images. However, sometimes it is a previous version of the basemap that you really want to see or use for a project.
