What feature characterizes a digital level in surveying?

A digital level in surveying is characterized by its utilization of a charge-coupled device (CCD) for data collection. This technology allows the digital level to capture and process height differences with high precision and accuracy. The CCD sensor converts the analog signals from the measurement into digital data, which is then displayed on the instrument's screen. This results in a more efficient and precise method of leveling compared to traditional methods that may rely heavily on manual calculations and adjustments.

The integration of a charge-coupled device enhances the speed and ease of data collection while reducing the potential for human error, as it automates much of the measurement process. This technological advancement allows surveyors to quickly gather and analyze elevation data, making the digital level a valuable tool in modern surveying practices.
