@fugarewe It's important whenever you set up a job that you're in control of the data. There seems to be confusion about what "the data" is. It appe...

I would check a nearby data sheet for super ceded control. It doesn't mean that they would have used the latest for the date but it's about all you ca...

@mathteacher Here are two AZ points that you might try out, FQ0759 and GP0641, I'm not sure what type of NAD27 they were I don't see the order for t...

@mathteacher Those points will be inappropriate for your task. They are converted points not measured points. What you need to find are points measu...

@kevin-hines I feel your pain. Years ago I got a request for a trailer park ALTA in a flood plain with no flood map. I put in a big cost and the r...

@holy-cow I got another request for a cost of an ALTA for a vacant rural subdivision lot. Two red flags, rando buyer not the owner (will only do sur...

@mathteacher It may be easier to find in NC, it's rare here that the NGS placed measured numbers on existing NAD27 triangulation stations. It's impo...

@mathteacher Math teacher QW0554 isn't a measured point. QW0575 is a measured point. The distance comparison isn't meaningful cause it's calculated....

@mathteacher No, this isn't about belief, it's about measuring. You are under the misconception that NAD27 was precisely laid out in a global contex...

@mathteacher Math teacher, I just showed you 50' and 300' differences. That's not the difference between the two earth centers, that's the big error...

@mathteacher You're so close, almost there. I'm not implying that NAD27 doesn't calculate using the Clarke Ellipsoid, what I'm saying is that NAD2...

@mathteacher I did a quick search to help explain. When 83 took over for 27 it became clear why 27 couldn't continue as the basis for satellite con...

@dougie I recently did a fire survey, plastic melted, metal caps, aluminum or brass were fine. I pulled one out that was plastic for a section corne...

I am having to order rebar caps, again. Which brand lasts the longest, in the sun? Thanks, Nate Hard aluminum or brass

@mathteacher Yes, again however, there wasn't anyway to step outside the monumented control points, and they aren't all that accurate, especially man...

@mathteacher When you calculate in NAD27 you calculate the grid scale and the elevation scale for each line, in TM it's the mean of the easting givi...

The new line in a BLA can be considered an original survey where it's unattached to the senior lines. Much like a subdivision all the interior corners...
