CST Level 1 Land Surveyor Certification Practice

Which of the following is a method used to measure land boundaries?

1. Laser scanning

2. Redlining

3. GPS surveying

4. Contact tracing

The correct answer is: GPS surveying

GPS surveying is a method used to measure land boundaries because it utilizes the Global Positioning System to determine precise locations on the Earth's surface. GPS technology relies on a network of satellites that transmit signals to GPS receivers to calculate accurate position coordinates. This method allows surveyors to establish property lines and boundaries with a high degree of accuracy, making it essential in modern surveying practices. In contrast, laser scanning is primarily used to create detailed 3D models of objects or environments, not specifically for establishing land boundaries. Redlining refers to the unethical practice of denying services or opportunities to residents in certain areas based on race or ethnicity and does not relate to land measurement. Contact tracing is a process used in public health to identify individuals who have come into contact with an infectious disease and is unrelated to surveying or land boundaries. Thus, GPS surveying stands out as the relevant method for measuring land boundaries.
