Stadia surveys are most commonly used for what purpose?

Stadia surveys are primarily used for gathering topographic data due to their effectiveness in measuring distances and elevations. This method allows surveyors to quickly collect information about the terrain's features, such as contours, slopes, and elevations, which is crucial for creating accurate topographic maps. Using a stadia rod and theodolite or total station, surveyors can establish relationships between points on the ground and represent the terrain's features in a form that is useful for engineers, planners, and architects involved in land development and construction projects. The application of stadia surveys aligns well with the broader needs in topography, making it the most common purpose for utilizing this surveying technique.
