Photogrammetry
Photogrammetry is a technique used to measure and analyze physical objects and environments through photographs. In geodesy, it involves capturing images of the Earth's surface from various angles, typically by drones or aircraft. By analyzing these images, specialized software can calculate accurate dimensions, shapes, and positions of features on the ground. This method is valuable for creating maps, surveying land, and monitoring changes in the landscape, as it allows for precise measurements without needing direct contact with the area being studied.

Photogrammetry is the science of measuring and interpreting photographs to gather accurate information about physical objects and environments. It involves taking multiple photographs from different angles and using specialized software to create detailed 3D models or maps. This technique is commonly used in fields like architecture, archaeology, and engineering, as well as for terrain mapping and urban planning. By analyzing the photographs, one can determine distances, volumes, and shapes without needing to physically measure the objects, making it a valuable tool for visual documentation and analysis.
