The Dewalt is awesome for that. And for setting monuments in hard ground, it's one of our best tools.
Ahhhh, I've got to speculate since Florida is Sectionalized that GLO/BLM manuals will be included in your procedures. There will be DOT manuals, board...
I don't know what GPS program you have, but Trimble will give you the Grid to Geodetic north conversion. Then you can get the mag and historic mag rot...
@bstrand You always want to think about how things get messed up. I learned the same way, put in a 2' WC on the street side and it got used as line...
This is the section discussing WC's in the 2009 Manual. As can be seen line a line tree the WC becomes an angle point, assuming...
@bstrand It's like a line tree, the point being the line is run, for some reason the corner can't be set, maybe it's in a creek, the line is run to...
@bstrand I'm not being clear I guess. My example is retracing original monuments. The WC isn't being set, it's being recovered from original notes ...
@bstrand Exaggerated sketch: The kink happens at the WC set from the south. Then line is held to the next monument to the north instead of exte...
And technically, a witness corner isn't necessarily "on-line". A witness corner 100' south of the E1/4 of a Section creates an angle point in the sect...
@holy-cow Our legal description programs included the delta as a default so I guess we just followed along. Looking back at some pre-computer descr...
left/right, Delta, Radius, Arc Length, Chord Bearing, Chord Distance.
@norman-oklahoma That would change the dynamic. It would be the same as retracing an 1880 GLO survey,,,,,,,,, use the bearing basis the original wa...
@norman-oklahoma A two degree convergence is large. When doing retracements you have to be aware of the convergence and deal with it when necessary...
State plane there is fairly benign, 69ppm, the LDP is quite precise at 3ppm, 3ppm at those distances is pushing the limits of modern measurement devic...
I'm with Bruce on this one, we're lucky to be able to check mountains of DOT static run control, they're probably over the top with their surveys, but...
Two stone examples: I went through most of a township. The first example is a found marked firmly set stone, 140 years in place so I left it with...
Two main issues with a single base are multipath interference and is the receiver over the point at the HI entered into the unit. Using a second base ...
@shelby-h-griggs-pls Would love to hear some real world results from one of those products on a large scale project.
I wonder if one of the services provided by vendors like the Trimble Centerpoint RTX system would be exactly what you need. For that size of project i...
Yes ground or grid, but from the xlckpx's wording it's about grid,,,,,,,,I think. Ground distances will be smaller by the ratio of approximat...
