Hello.
Unfortunately our professor (after performing a relief through total station) provided us with .gsi files, but did not explain how to use them. the total station was of the leica brand. I don't even know if this is the right section, but is there any good soul explaining to me and my companions the meaning of these rows and columns? Thank you:frown::frown::36_1_4:

first row -> station 100; coord st. x=1000000, y=1000000, z=1000000; alt. strum. 1.55
second row and subsequent -> celerating points so arranged:
point name, azimut, zenit, inclined distance, h prisma, code
