Briefly describe the use of each of the following instruments in conventional ground surveys below:
(a) total station
(b) level
(c) measuring tapes
(d) electronic distance measuring devices
(a) The total station is an electronic theodolite and distance measuring device. It
is used for measuring angles in both the vertical and horizontal plane as well
as distances.
(b) A level is used in conjunction with a graduated leveling rod to measure
changes in elevation.
(c) Measuring tapes are used for the direct measurement of horizontal distances.
(d) An electronic distance measuring device (EDM) is used to measure distances.
When an EDM is used in conjunction with a slope reduction calculator, it can
also measure slope and height distances. These devices allow for distances
and direction to be determined from a single instrument setup.
