You have this somewhat backwards. Cities have loads of data that define property lines. They could keep it on paper, but more and more they keep it in computers now. Surveyors take that digital data and convert it into its precise real world marks. This has literally nothing to do with whether the real world digitizes well, and if really stretched only proves that it certainly does because that's the entire basis of property grants. Further, pointing out a massive civic project in the middle of a large city as some sort of counterpoint, when it is in reality still not that complex at all, doesn't make your case.
