Yes, it's very explainable, GLO notes are full of mistakes.

.08' in 300' off the top of my head is 267PPM. This is a gross error, you would need to be +5000' above the ellipsoid for that to work because of scal...

OleMan, even more on point is to teach yourself geodetic calculations from your measurements. I don't really know how the old timers did it, I know th...

It was way more intensive to survey with state plane prior to computer programs doing it all for you. Learning to reduce instrument data to geodetic c...

It makes it worse when there are two BLA's (which have to go through county review and approval) on this property and still the GIS didn't follow them...

+1000%

There will come a time where everything is based on Lat, Long, Elevation. That's real surveying. Ironically, the GLO/BLM did the entire PLSS that way,...

I've been involved with similar issues. They can be fixed, but it gets complex. One I did dragged on and on, all the stake holders had to agree to a r...

I believe you're correct Mathteacher. But there are more things afoot. The push is to put 0degrees longitude through Rosewell, NM. Then things will fi...

I doubt that will ever work. Users will want "official" projections that are available as defaults in all the major programs such as AutoCad, TBC, wha...

[/quote] I'm not sure what the question is referencing. I'd need to hear the question and answer. I see the NGS zone design criteria has been relaxe...

DOT multiplies the coordinates. I used to scale around a point, back in the instrument days we would develop a scale factor between two NGS NAD27 monu...

Lets get the terms correct, Combined Scale Factors are related to a 3d point or the midpoint along a line connecting two 3d points. A Project Adjust...

Hope he gets better soon!!

Oh my!! Another story about Texas surveys. After all those comments about the superiority of Texas surveying, how all of us PLSSers were unwashed bumk...

For property survey filings please use Lat, Long on the tie, forget any XY coordinates. Tell me the basis of bearings, if you express State Plane then...

I get the sense Landbutcher might be in a state that requires ties to old NGS monumentation. Hopefully these have been occupied by GPS recently to get...

The HARN point I was checking into has an 83(2011) adjustment shown. It's a CBN. I occupied a point a couple of miles NW of it and drove over, hit it ...
