The surveyor initial reads a backsight measurement (BS) off of a leveling rod held by his trusty assistant in excess of the benchmark in a.
The accuracy of only one angle measurement can't be identified, but Considering that the sum of the interior angles of the polygon is often (n-2) × one hundred eighty, It is doable To judge the traverse as a whole, and also to distribute the accrued glitches amongst all the interior angles.
Now we have our possess logistics facilities to move any project site. Most of all, we feature our tools along with our Laptop computer making sure that we are able to in a position to organize the information processing in the working district. But we acquire no less than two days to move to hilly locations i.e Chittagong, Khagrachari, and Bandarban. We also do the same for coastal spots i.e Sandip, Saintmartin, and Kuakata.
This policy limitations the utility of OPUS corrections to static positioning (although the accuracy of extended kinematic observations can even be improved).
