Move from Google's MyMaps and Google Earth to Google Tour Builder. View an existing tour or build your own at https://tourbuilder.withgoogle.com/
Google Tour Creator takes it a step further and allows you to add points on 360 degree videos. You can use imagery Google already has rather than creating your own if you want. You can also use images from street view or discrete images if you don't have a 360 degree camera (see article).
