I would like to include additional aerial imagery in my map, but I'd like for it to be underneath the other ESRI base maps, so that I can show a street map or topo, for example, over the top of this other imagery.
All I seem to be able to do is place this imagery on top of the ESRI basemap. If I add it as a basemap, then it is still on top of the topo. It seems like I ought to be able to control the draw order of this.
