See an "Earth View" as in Google Maps

I use SunCalc to find locations for good sunsets to photograph. A switchable Earth View as in Google Maps would make it easier to identify an exact location. Possibly street view would further aid this visualisation. I currently switch between SunCalc and Google Maps. This works but is inefficient. I appreciate that the data to do this may prove too expensive but if you don't ask, you don't get. Many thanks, Jeff
