You can fix this issue in the RINEX file rather easily using NOTEPAD, BUT, you need a good understanding of RINEX File formatting. Loyal

This issue doesn't JUST affect "surveyors." What about; Title folks, attorneys, GIS technicians, historians, genealogy researchers, the list goes on &...

2 million dollars...and what Cow said!

Good to hear, everything is as it SHOULD be! I have seen enough "not so straight" rods that it's the first thing I check when I buy a new one. Loyal

I hate to state the obvious, but if the electronic bubble and the [spirit] rod bubble don't agree regardless of rotation, then ONE (or BOTH) of them a...

Scott, GREAT post! BTW, you have some really cool toys to play with too. Loyal ?ÿ

Good comment, and all too true in many cases. HOWEVER, that attitude concerning the "science side" of surveying is no longer valid in MOST surveying s...

Lee, don't get me wrong here, your statement is essentially TRUE. The 2022 Vertical Datum will be in essence a Geoid Model based on a Gravity model, a...

emmmmm...yeah, BUT that's not entirely true. It will be "tied" to the CORS Network (and thereby to the NSRS), and we will use GPS to "access & uti...

Here (I hope) is a Gravity Map of Iowa, which definitely factors into the "shape/slope/etc." of the GEOID. Loyal
