Here are the coords for the translated and rotated points. I translated your points by moving all of them so that 500 moved to 100. I then rotated aro...

It is easy math for the translate. And you have it right.

I will if someone doesn't beat me to it, but I can't do it today.

Shot 4 points with RTK today then used a gun between them all. The worst miss was 0.02'. That is unusual but in a good way.

You might go here and then call the coordinator listed for the area in which your road exists.

@rfc This is just a google result. I have no idea if it is correct or not. Google Earth uses the international foot (0.3048 meters) for its intern...

@rfc Those coordinates shown in the picture would about 3.33' away from the same coordinates in US survey feet if they were placed on the ground. I'm ...

@rfc Vermont State Plane coordinates expressed in International feet will put you in a different place on the ground than Vermont State Plane coordina...

If you are using coordinates in the millions. for example 1,000,000 northing 2,000,000 easting for US Survey feet then International feet will be 1,00...

Ellipsoid height - geoid height = ortho height.

@peter-lothian That was what I was thinking. If that screw is within 0.02' of record distance, I'm betting it does not mark the location of the stone ...

How close does the distance have to be to match record for a stone?

@norman-oklahoma Are you arguing that monuments can't be controlling if the parties were not aware of them at the time of exchange of deeds? I can sho...

@bill93 Every metal detector should add that capacity to discharge magnetism to an area where there is no tell tale sound from the detector. The first...

@jimcox I can't even figure out what the heck you bought, except I know it is some type of lumber. 🙂

That statement in the manual is so absurd it serves as a good example of why rules should not be used in place of judgement.

If more people had to directly contribute to the payment of liability insurance premiums, there would be more blunder busting occurring.

Do I read the Babel Hathi trust excerpts correctly? They all reaffirm that original monuments should be held except for the Seattle case where they we...

Pin cushions are most definitely a problem. They reflect a lack of diligence in finding existing monuments. They reflect a lack of judgement when a se...

@gary_g Are there states that allow PK or concrete nails to be set as boundary corners?
