Abstract

Total stations being a lightweight and handy integrated equipment, is being worshipped as a solution for acquiring correct data for timely project completion in surveying. Though there are emerging technologies like the Global Positioning System (GPS), Unman Aero Vehicle, and scanners, the total station remains the preferred, and dominant instrument currently in surveying because of its high accuracy, durability, and incorporates many functionalities than others. However, this high accuracy is dependent on a clear line-of-sight. In this research, selected temporary obstructions of opaque nature were used to obstruct the line-of-sight between the instrument and reflector at regular time interval. This was intended to examine the effect on the accuracy of distance measurement. It was observed that, significantly the obstructions resulted in readings that fall within the accuracy of ±2mm. In practice, all the readings are not likely to be obstructed and that would therefore further improve the accuracy.
