Makes you buy it to see property lines! I'm sure it's not even accurate, just like landglide and my town's GIS map! Both say my property line is 20-50ft back from where my actual property line stake is! Which is accurate to my paper property line map from the town! Don't trust digital maps! Even the internet says they aren't accurate or within 20-50ft. Well thats a lot when you neighbor'spiling updead lawnmowers and trash on your property! A metal stake from a surveyor is 100% accurate!
