@mightymoe Exactly what I do in the math world. Before Computer Algebra Systems (CAS), I would spend as much time as it took to integrate a difficu...

@mightymoe Moe, you're a pro who knows his equipment and how to get it to produce results that fit those job requirements. What seems to come up re...

@bstrand My rheumy old eyes led me to compute a combined factor using the two ground estimates instead of using the grid estimate and a ground esti...

Yep. I pushed a wrong button. Sorry about that.

@landbutcher464mhz But the CF you gave doesn't produce the result you claim.

@mightymoe So, what does Access really do?

@landbutcher464mhz I need to reconsider my answer to your original post. You wrote: I know for sure that my GPS measures grid when the CF is set ...

Here's a bit more AI speak based on Jim's comment: Can I measure in grid rather than ground? In that case what would happen with a...

@landbutcher464mhz Remember, this is ChatGPT's example, not mine. The "yes" in the copy and paste is my asking ChatGPT to show me its example. Caut...

Here's a cut and paste from a ChatGPT session about Access and combined factors. Corrections and comments are solicited and welcome! ...

@mightymoe Indeed. Just a cursory look at Montana State Plane coordinates near the Northern and Southern Borders shows that the elevation factors a...

@mightymoe That's an interesting challenge. I hope that you will permit me to substitute NC for CA. I'm more familiar with my home state. My star...

@mightymoe But the question is about the use of a combined factor of 1 in survey software calculations. The existence of a point with that characte...

@mightymoe Might not be able to do that in the High California Desert or Montana, although Montana's single-zone system might create the right comb...

@field-dog Generally speaking, ground distance and grid distance will not match regardless of the source of either. It will happen, though, when a ...

@landbutcher464mhz Thanks for the the invite. We're roughly 2400 miles apart, so at 200 miles a day (long trip for me is 100 miles one-way, 200 tot...

@mightymoe Moe, you and I often disagree, and I yield to you in all things surveying. However, 1.000 is a legitimate combined factor, just as 1.001...

The answer, assuming no errors, either human or machine, that your TS is reporting ground distances, and that there are no serious elevation changes t...

@olemanriver You're pretty much spot on. There are two errors that you can make: 1) Reject good datal or 2) accept bad data. A 95% test lowers th...

@john-putnam Indeed. I've marked axes on a tile floor to teach coordinate calculations. Students calculate oblique distances from coordinates and c...
