What type of data is often collected by UAS in surveying applications?

The type of data often collected by Unmanned Aircraft Systems (UAS) in surveying applications includes topographic and geographical data. This is primarily because UAS are equipped with various sensors and cameras that can capture high-resolution images and precise measurements of terrain, elevation, and land features. This capability makes them particularly valuable in fields such as construction, agriculture, mining, and environmental monitoring, where understanding the landscape is crucial.

Topographic data provides detailed information about the shape and features of the land's surface, while geographical data might include coordinates, land use, and vegetation types. Such data is essential for creating accurate maps and conducting analyses that inform decision-making in many industries.

In contrast, the other options are more specialized or do not fit the general use of UAS in surveying. Thermal imagery, while useful in specific scenarios (like inspections or search and rescue), does not encompass the broader range of data needed for general surveying. Audio recordings are not typically a focus in surveying applications, and safety and compliance reports are usually generated as a part of operational procedures rather than being primary data collected during a survey.
