I'm trying to publish a map document as a service from ArcGIS Desktop 10.3.1 to ArcGIS Online. It works just fine, except that ArcGIS Online automatically loads in a basemap. This usually isn't an issue, but I'm working with a map of Io, one of Jupiter's moons. A basemap of the earth is less than helpful.
Is it possible to publish a map document as a service and only get the map document without ArcGIS Online's basemap?
