I pulled out my smart phone at my grandfathers house this afternoon and used it to locate his property corners. The smart phone map with parcel lines got me within 5-10 feet of the corners. I was wondering how this technology will affect the land surveyor in the future. The fact that these lines are from tax maps and not very accurate, I believe this will help the surveyor gain work from possible property line disputes that neighbors wouldn't have known to exist in the past. What is your thoughts of how this will help or hurt the Land Surveyor?
