Maps generally default to a roadmap format as their base layer. However it is common for providers to offer additional base layers, such as satellite views, which the user can select. Selecting one of these alternatives completely replaces the default base layer, rather than it being combined or overlaid therewith.
Some map and API providers allow the user to choose between alternative lbase ayers by default. Others, particularly those that require explicit configuration of layers, allow multiple layer sources to be configured, but may or may not provide a standard control enabling users to choose among them.
Embedded Google Maps include the satellite/street map layer selection control by default.
