this method for roads and long fields .. what about for a ground I mean before building a building ..? doing that network leveling .. hope u got my point
One thing that confused me is that how did you decide the numbers of the backsight and foresight? I mean exactly how you come out with these numbers, especially for the backsight?
Asuka Graham in the field, you get the numbers by looking through the instrument (level) and reading the top middle and bottom wires. In the video he’s probably using notes from a previous bench run or just came up with three numbers that worked for the purpose of the video.
Can any body help me? Why can I measure the elevation at sea level and I can measure the elevation of the mountain top and every foot in between but I can not measure the 8" per mile squared according to the pythagorean theorum of geometry and spheres for earth to be a spinning ball with a circumference of 24,901 miles?
I need clarity on this please, While calculating the stadia, you said T - M x 100 (which is given as K), M - B x 100 and you add both numbers, the answer becomes your HD... you did another video under 3 wire leveling and you said, for stadia, T - M, M - B you add your answers then multiply by 100 = HD Why are they different? Perhaps which one is the correct one?
Now explain how any actual accuracy can be acheived on an ever curving surface. The Earth has a perpetually curving surface right? Right? Wrong. The only way leveling can acheive any accuracy at all is because the Earth's surface is flat, and measurements are taken in relation to a level plane. This is common sense.
johnnybunz - Common sense eh?! So WHY do we have to compensate for vertical error when completing a geodetic survey (over long distances) if the earth is flat? Wait! I got it! it's magic right? Am I right?!
to get your stadia you can also subtract the top wire with the bottom wire, remove the decimal point. like 592 - 301 = 291 ... 781-501 = 280
Something my lecturer struggled to explain. Thank you
I learned something simple yet helpful. thank you.
Great explanation…thank you so much!
Great video, really helped me grasp this concept. Thank you!
nice work i got my concept clear about bs fs thankas a lot and keep it up
brilliant, you're handwriting is also very neat
yes! =)
Appreciate we can understand your English accent. Some videos are very hard to understand on this subject
I learned a lot from this video. Thanks so much.
How do I can get the backsight?? If the elevation on tht benchmark is 1000
is the Top Mid Bottom are the reading of Top = C Mid= B Bott= BM?
Thank you, well explained!
this method for roads and long fields ..
what about for a ground I mean before building a building ..?
doing that network leveling ..
hope u got my point
This lecture is very good thanks teacher
th-cam.com/video/XPCgGT9BlrQ/w-d-xo.html 👍👍💐💐
Yes is a very good lecture
Sir where did you get 7.81/ 6.41/and 5.01 that is actual reading? or example only ...
th-cam.com/video/XPCgGT9BlrQ/w-d-xo.html 👍👍💐💐
Awesome 👍👍👍 and thx 🙏
You’re very welcome!
My question is....why would you need to determine all these values and do all the maths....when we've got total stations?
thank you sir i note a one point what is k=100 plz sir explane
Hey,.. Thanks for all that show,.. But how can you conclude,.. Let say now,.. Field application
Your handwriting is neat
Why we calculate stadia?

best video and nice work
thank you , your videos are helpful

That is the difference between a "foot" and a "US Survey foot".
I need clarity on this please,

I just saw another video were you clarified that.. it's the same thing all together..
Thanks..
How can we get Bench Mark (BM) result ?
From Data GPS Measurement /GNSS
Wow, I can't believe it! A non-Indian punjabi with a surveying video.
btw I think K is the factor
So helpful
Thsnks

sir....great way for me...but how can we set BM Elevation? Thanks
Bory Koek BM from water level sea. level of sea relative flate .
what is a DoubleRodded Leveling

it's really good
SIR ...plzz explain thay sum in RISE and FALL method.
thax, I know also much advance technic
thanks ...👍

thx
Tq bro
butiful
nice
It's amazing to me the amount of people that thing level is not horizontal🤢

Now explain how any actual accuracy can be acheived on an ever curving
surface. The Earth has a perpetually curving surface right? Right?
Wrong. The only way leveling can acheive any accuracy at all is because
the Earth's surface is flat, and measurements are taken in relation to a
level plane. This is common sense.
LMFAO
flat at only poles
this is plain survey. curvature of the earth isn't concidered
johnnybunz - Common sense eh?! So WHY do we have to compensate for vertical error when completing a geodetic survey (over long distances) if the earth is flat? Wait! I got it! it's magic right? Am I right?!
If your distances from instrument to the rod is roughly the same the curvature is taken care of. Think about it....
So helpful
