The primary disadvantage of using total stations is their reliance on line of sight and range limitations. They cannot measure what the laser beam cannot directly see, often necessitating the combination of Total Stations with GPS methods for comprehensive survey coverage.
Total stations operate on the principle of measuring the deviation of the reflected light's wavelength. They are capable of measuring distances with an accuracy of approximately 2-3 millimeters per kilometer and angles with an accuracy down to 1 second (1/3600 of a degree).
Field procedures are routine processes or scripts that transform values in a single database column. They are triggered whenever values are altered or new values are inserted, enabling transformation (encoding) of the value before it's stored.
Errors in total station surveying can include vertical and horizontal collimation errors, centering errors, and eccentricity errors. Some are due to temporary adjustments (marked as T) while others result from permanent adjustments (marked as P).
To properly set up a total station in the field, align the instrument to zero degrees on the horizontal axis, ensure a reflector is in the line of sight, and use the Electronic Distance Measurement (EDM) function to position the reflector at the correct distance. Record this point by marking it with a stake, which is then used as the entered coordinate in the system.
