Answer 1

i believe google is partnered with ESRI, and ESRI is “big data”, hosting much of the data for most municipalities and governments in north america & europe, so I imagine a lot of that infrastructure information could be shared between companies. I have nothing to back this up, but in this day and age data is king and ESRI owns the castle when it comes to municipal/government spatial data
