What is photogrammetry?

Photogrammetry is defined as the science of making measurements from photographs, especially aerial photographs. This technique involves capturing images and extracting precise spatial information from them, enabling the determination of distances, areas, and even volumetric measurements of objects and terrain.

This method has various applications, particularly in cartography, surveying, and mapping, where accuracy in measuring the physical world is essential. In modern contexts, photogrammetry can be applied to various types of imagery, such as satellite images or drone-captured photos, allowing for the generation of detailed maps and 3D models of the earth's surface.

The other options focus on different aspects of GIS or related technologies but do not accurately define photogrammetry. Integrating GIS with physical models, creating 3D models from GIS data, and visualizing GIS data refer to distinct processes and methodologies within the broader field of GIS and do not encapsulate the essence of what photogrammetry entails.
