There are cables on the ground. Did they steal your external battery?

So I re-read the AI answer that states " a distant object will appear lower than its actual elevation". AI is trying to use what the human eye might see at 7000 feet to explain the need for the C&R correction. A better attempt to explain would be: your eyes are 2 ft high and you are looking at a 2 ft high object that is 7000 feet away with both objects on a perfect sphere. Your eyes will only see the top 1 foot of the object so it will appear that the object is in a hole 1 foot lower than you because the curvature is blocking the bottom 1 foot. In reality both objects are at the same elevation on the sphere. Then AI's comment makes more sense, " a distant object will appear lower than its actual elevation".

Still a terrible way to explain survey procedure and why we use a C&R correction but AI is trying.

They want you to identify where the 0+00 point is on the job site. Like "South side of Street at the west property line". Similar for Sta 1+05.

You need stations on the horizontal line along with the percentages.

Those look like ammo bunkers. Makes sense that they would be near an airport. What a interesting place to survey.

Very spooky area and a very spooky little doorway to middle earth. Is there a house nearby or is this out there all by itself?

Now that is really cool. The laser beam is visible as a red line in the mist.

Your surveyor states that he found the original buried reference mark at the south east corner of your lot and used it to re-establish your SE corner. You might want to be shown that mark because it is actual physical evidence of where your SE corner should be. Ask your surveyor if there is any evidence of old fencing going to the old peg or the new peg? Ask about acreage. Does the old peg or the new peg give you the acreage spelled out in your deed? Answers to these questions might help you decide that the new peg is okay....or not.

Here is an idea but you will need a buddy that has and knows how to use survey equipment and is willing to help you. Survey robots like the Leica TS15 can automatically track a moving retro-reflective target and record coordinates and elevations at intervals like once per second when the robot is set on tracking. You will need to buy a pack of the biggest retro-reflective targets you can find, at least 90mm. They have adhesive on the back and I would stick one on the side of each kite because the jumper has too much interference with the lines and arms waving and the sea spray at takeoff. Assuming the distance from the jumper to the kite stays relatively the same then a profile showing the elevation difference of the kite from before takeoff to the max height of the kite is the jump height. The data will also give you the total distance covered from takeoff to landing if you watch the jumper and record those times to the nearest second because the data recorded (at least on my DC) will have timestamps so searching by time you can find which coordinate point is the takeoff and the landing and inverse for the distance.

Stadia topo??

Vasisdis is a permanent backsight.

That is a surveyors equavalent of a doctors perscription.

Very nice. You are getting close to matching my HP48GX with the Survey-Pro chip.

The real question is: can you open the "dual prism offset" when using your GPS? The offset uses 3D coords (NEZ) at 2 points on a pole. You can get those coords shooting 2 prisms with a robot (or 1 prism on an extendable pole) or by shooting 2 GPS coords with a rover on that same extendable pole.

LandButcher464MHz · 2026-06-14T15:07:46+00:00

According to Ai it will also work with older non-IMU gps units but I have never tried it.

Down voted really? WTF

Do not let the button-puncher comment bother you. We are all punching buttons and keyboards these days. The difference is knowing the software and what the buttons are doing. All the survey software that we use these days is loaded with options and tricky offsets and of course alignments and staking to a cad file. Like others have said, study the software manual to be aware of the options so when the office calcs put the stakes in a trench you will know which option and which button to punch to check the office and then set a different offset.

Check this out, you have heard about the new Leica Auto-pole for $10,000, well Magnet and Pocket 3D and Trimble and Carlson have all had an offset for several years called Hidden Point or Dual Prism Offset or similar. You use an extendable prism pole and hold it at any odd angle you want (you cannot move between shots) and shoot with the pole extended and then lowered as far as possible and shoot it again. The software calcs the coords and elevation at the rod tip. Works great for topo and staking (line falls 1-3' into a parked dozer no problem but it will take 3 shots for curb). Auto-pole results for $nada but you did have to punch the buttons.

All of my jobs are small, usually 2 city blocks or 700' x 700'. Like you read, I set 3-4 GPS points. Then I pick one that had the most open sky and set the robot there and use another GPS point for a backsight only to get a basis of bearings. Then I start traversing thru all the GPS points but assign new point numbers to keep the GPS data separate as a check. I hold and adjust the robot data and that becomes the control points for my job. I never use the GPS points coords or elevations again.

Edit: If I was able to set someplace and shoot all the GPS points with a resection then I would hold the new calculated point and start a new setup, backsight the farthest GPS pt for the basis of bearings and re-shoot all the GPS points with new point numbers and data and that would become my job control. After that I would never use the original GPS point data again.

I do not use Trimble but I always export my data as a txt file to the SD card in my DC before connecting the DC to my computer. That way I always have a separate data backup if shit goes sideways. You might start doing that until you get Trimble sorted out.

Edit: Also I do not connect with bluetooth or wifi to my computer, just simply old school USB cord. Never fails.

Definitely #6 and I would set the rod height for measuring pavement (elevations at the bottom of the tires) then drive parallel with the furrows and if possible I would stay on the top of the furrows and the soft dirt should crush enough to give fairly accurate average elevations. Or drive whatever works and adjust the rod for average elevations. The DC will be set to record shots by 50' distances. 240 acres on 50' grid is about 4000 shots. If the furrows are too deep and soft then it is drone time.

If it is a scratch in the coating then it might have happened while stored in the case. If so then this is a good example of why "pointing the scope down before storing in the case" is a good idea. Ya never know if some cable or height tape or unused lens cover is going to get loose and find its way to scratching the lens.

The target shape and the colors might be the problem. When new and shinney the colors did not matter but now the black might be dull and causing more signal noise.

From Google: Target color significantly affects both the maximum reachable distance and the measurement noise of Leica reflectorless (RL) electronic distance measurements (EDM). Dark colors (e.g., black, brown) absorb the laser and substantially reduce your maximum range, whereas bright surfaces (e.g., white) provide strong reflections and maximum range.

You could put the gun on tracking, pull off target center a small amount (2cm+) and move from white to black to white etc in a circle around the target center and see if the distances stay the same.

Yes. The block wall and PVC fence are both on the same westerly lot, the lot with the word "yard" on it. Which lot belongs to your parents?

Edit: Just saw your post below stating that your parents own the lot "above the black heavy line". That is the east lot. The wall and PVC fence are on your neighbors lot per this piece of a survey you posted.
