New to OSM, advice and pointers for distance calculations

Hey folks!
I am new to calculations with OSM data. I am exploring a new project, and I want to use OSM data to highlight certain points of interest.

One of them is “which point in this area is the farthest away from any street”. How would one go about thinking about this problem, and which literature would I use?

I think this kind of thing is called a “pole of inaccessibility”. The wikipedia pages talks a bit about computation methods. The polylabel algorithm is reasonably easy to implement (i.e, even I could do it! :slight_smile: ).
