If we could get away with only survey 1 point every 100km we would
have already have finished earth some years ago and be onto the next

I suspect you will need to survey which houses are nearest each road
junction plus any gaps, I suspect surveying a few points every 100m is
going to be nearer what you need. With or without having code to
extrapolate house numbers. 100km is the distance from hmm Washington
to Baltimore or London to Oxford (give or take) if your going to only
survey a few points in that distance, I think we have more points
already in the database.
