What does the term "photogrammetry" refer to?

The term "photogrammetry" specifically refers to the use of photography in surveying and mapping processes. This technique involves capturing images from various viewpoints, which can then be analyzed to extract precise geometrical information about the objects captured. By measuring distances, dimensions, and other spatial relationships from photographs, photogrammetry allows for the creation of accurate maps and 3D models of the terrain and objects.

In practical applications, photogrammetry is commonly used in fields such as cartography, architecture, engineering, and archaeology. It can include aerial photographs taken from drones or aircraft to create detailed topographical maps, enabling effective planning and resource management.

Understanding this definition is crucial for geodetic engineers, as they often rely on photogrammetric techniques alongside traditional surveying methods to gather data and present it in comprehensible formats for various projects.
