- This video elaborates how to orient the instrument using a coordinate and a direction. After orienting the instrument you will be able to obtain details of the surrounding features (Topographic Survey). Further this video elaborates all the basic steps that should be followed before orientation of instruments such as creating a job and adjusting EDM settings. Hope you'll follow all the steps and learn how to orient the instrument.
Good Explanation...👍
Great sir❤
Thanks
nice
Clear cut your explanation...
Good ✌️
Setting up on arbitrary unknown point, how do you set the total station azimuth to match TRUE NORTH (same as geodetic north of GNSS) for reference? (not magnetic north or approximate).
A very good question. a very few people know the exact method. Usually you should have a clear night sky where you can see the stars clearly. Then setup your Total station at the point you need. Then you need to target to a star which is rising and track its path (you have to move the telescope in the horizontal plane and the vertical plane using fine adjustment screws). you will notice that you have to elevate the telescope with the rising star (Vertical angle get reduced) and at one moment star will stop the rising and will start to set. That very moment (where you observe the lowest vertical angle ) you have to stop the horizontal rotation of the instrument. Now you have targeted into true geodetic north or south (depends on the hemisphere you live ) then you can rotate the telescope about trunnion axis. Now you can put a peg on the ground. this peg is exactly in the direction of Geodetic North. So next day you can refer that peg as the Geodetic North only for the point you setup the Total station last night.
Sir, requesting you to please eliminate this background music in your future videos please !!
Too much noise
