With ever rising precision in construction industry, the total stations are becoming a valuable asset to our construction industry. Its high precision, ability to collect and store data and the ease of handling makes it ‘go for’ equipment for any project. Surveying is a technology that uses instruments to measure the position relationships between points on land and express shapes, areas and other aspects by figures or drawings. The history of surveying dates back to ancient Egypt. The pyramids, which survive to this day, could not have been built without accurate surveying technology. The four sides of a pyramid are of the same length, and the four surfaces have the same surface area. These surfaces, which face north, south, east and west, converge at a single point while maintaining a uniform angle. This would not have been possible without accurate surveying methods.
