Globe representation of hierarchy data

I have a treemap data hierarchy I would like to 'apply' to the globe.

Idea being that the top level may cover a country, the lower levels map over the land based areas of planet - state/city/town etc - the lowest being the 'buildings on a street'

Objective is that someone searches for something in this treemap and the globe finds it and navigates drill down to the area.

Newbie to this - have some experience of coding but a while back now.

How best to go about this - I looked at the demos and cannot visualise it from them - any advice on how to start with the data representation?

Note that I don't care at all about the countries or locations - the planet is purely to map a familiar concept for users to then easily spin and navigate against.

Thanks in advance
