"GPS Coordinates"

Wayne Griffin made an interesting (and probably insightful) comment below:

“What is kinda spooky to me is how we've gotten to almost take GPS for granted. Meanwhile, NGS keeps re-inventing it. Now we have velocity. Yikes. I get re-spooked every time I fire it up.”

How many folks feel as Wayne [apparently] does about the current (and future) evolution of the NSRS?

I have had several conversations recently with highly (and some not so highly) respected Land Surveyors that indicate similar feelings on the subject.

What's the general consensus among the Land Surveyors here at POB?

Does the idea of a dynamic NSRS bother you?

The new (sixth) realization of NAD83?

How about the NEW NAD (or NARF or whatever) that is planned (and NEEDED BTW).

What about the prospect of a pure gravimetric vertical datum?

These are all things that we are going to have to deal with whether we like it or not (and some other things as well).

I'm [more than] a little curious.
