Idea Summary
We (a customer using Spatial for years) would like to use SpatialStudio and new APEX Map component with own, custom background map (Mapviewer's basemap)

Use Case
We are creating maps, we are the source off accurate, most current maps and data. We also design applications, both internal and external. We just cannot create applications based on inaccurate maps (like OSM, Google and others). 

Preferred Solution (Optional)
Pls, provide custom map as background map, like we had in previous legacy APEX Spatial plugin.
