A lot of these comes down to structuring law and bureaucracy to be digitizable. In Denmark every cadastre is throughly mapped and logged, and have been for a long long time. As a result we have a national addressregistry with a public API. This way your digital solutions will never really get an address wrong.

I think you could build something similar with OpenStreetMaps if your bureaucracy sucks, but it’s a massive undertaking of course.

What surprises me the most is how countries that don’t do this, keeps track of all the other GIS related things. Like how much electricity or plumbing a cadastre will need. Or perhaps more important, taxes and property taxes.
