Hello,
With the help of the wp backend you can choose your default map type by using Add/manage map.
Go to the frontend map and apply following methods:-
1)To display regular view or roadmap view then click Map for Road View and Click to Satellite for Satellite view.
2)Similarly for street view than click on street view control(a small doll like in yellow color) and drop this doll into main map where you want to show street view.
This type user can view any map with their choice.
Thanks
