In the https://developers.google.com/maps/documentation/urls/get-started examples
- We can have a marker, https://www.google.com/maps/search/?api=1&query=47.5951518%2C-122.3316393
- Or we can choose a basemap, e.g., terrain, https://www.google.com/maps/@?api=1&map_action=map¢er=-33.712206%2C150.311941&zoom=12&basemap=terrain
But how can we have both a marker and terrain? I can't hack together a URL that will do it.
