How can I combine a
ReliefPlot with other geographic shapes? Since the
ReliefPlot is just a plain array of values, it is not clear to me how to project it and combine it with other geographic shapes, like administrative boundaries.
For example, I can generate a
ReliefPlot of Maine like this:
ReliefPlot[ GeoElevationData[Entity["AdministrativeDivision", "Maine"]], DataReversed -> True]
but how would I put, for example, an outline of the state of Maine on it or combine it with the locations of cities?
