Precise, yes. Accurate? That takes judgement and evaluation of all evidence available. You can’t take ownership of someone’s land away because your measuring stick is different than the guys’ 150 year ago.
The time consuming part is the research and recovery of potential benchmarks. Every Record of Survey, plat, and other land subdivision records will need to be reviewed. And if the border changes along route, it would require a new record of survey and monuments set.
Most Land Surveyors don’t like their previous work to be overturned and they could be liable for changes.
