A few weeks ago, you were insuating that relativity is like evolution on another thread.

My friend is a surveyor and he uses equipment from Trimble that is accurate to a centimeter. It’s not to cut costs as that equipment costs $$$. Yeah, if you are surveying between skyscrapers in a city, there will be errors, but most places, they work fine.

I know all about selective availability as my hobby is geocaching, and it wouldn’t be in existence if Clinton hadn’t gotten rid of it in 2000 (the only good thing he did do). This isn’t about selective availability.

Here is a Wikipedia article on it

and one from an astronomy class lecture in 2006.

"A few weeks ago, you were insuating that relativity is like evolution on another thread."

That is a lie. (getting to be more and more typical of evolution promotors)

Using GPS equipment is to cut costs. The equipment is cheaper than a good conventional setup, and it is easier to do for a one-man crew than to use a robotic total station. It reduces the training time because the software eliminates much decision making. Problem is that when there are any obstructions at all, you cannot predict the errors. Its like russian roulette to use it in those circumstances.

I can always tell when I've bumped into garbage that has been done with RTK near trees and buildings. The errors will be as much as half a foot, and will be near the obstruction. The points away from the obstructions will be good. Also the elevations are far less reliable - lots of vertical noise in the 1 to 2 cm range.
