What is Lehmann's Rule used for in surveying?

Lehmann's Rule is primarily utilized in surveying for the purpose of locating instrument stations in plane table surveying. This rule aids surveyors in determining the appropriate positioning of their instruments to achieve accuracy and efficiency in mapping and data collection.

In plane table surveying, the instrument must be set up at strategic points to ensure that the areas of interest can be accurately drawn and measured. Lehmann's Rule provides guidelines on how to align and establish these stations effectively. This is crucial because the fidelity of the survey results heavily depends on proper instrument placement.

While surveying may involve various calculations and measurements, such as earth curvature corrections or the weight of equipment, those aspects are not the focus of Lehmann’s Rule. Instead, it specifically addresses the arrangement of instruments, making it a valuable tool for ensuring precision in the survey process.
