Which application would use Prisms in survey measurement?

The use of prisms in survey measurement is closely associated with optical surveying techniques, particularly when employing Electronic Distance Measurement (EDM) instruments. In this context, prisms serve as targets that reflect the laser or infrared signals emitted by the EDM device. This reflection allows the instrument to measure the distance to the prism accurately, which is vital for various surveying tasks, such as establishing control points, measuring distances, or defining boundaries.

Optical surveying that utilizes EDM instruments requires precision and clarity in measurement, which is facilitated by the reflective properties of prisms. These prisms are often placed at predetermined locations, allowing surveyors to gather accurate distance data over large areas efficiently.

Other options involve applications that do not typically make use of prisms. For example, road grading analysis is more focused on evaluating and adjusting the surface of roads based on elevation and contour data, which can involve different surveying methods. Data entry into Geographic Information Systems (GIS) primarily involves compiling and integrating geographic data rather than measuring distances directly. Weather forecasting analysis utilizes meteorological data and models, which do not involve surveying techniques that use prisms.
