PHOTOGRAMMETRIES Meaning and
Definition
-
Photogrammetries is a branch of surveying and cartography that involves the creation and analysis of accurate three-dimensional (3D) models or maps from photographs. It is a highly specialized technique that uses photographs and their measurements to extract measurements and data about objects or features in the photographs, in order to recreate accurate 3D representations.
The process of photogrammetries starts by capturing multiple photographs of an object or an area from various angles and positions. These photographs are then analyzed using specialized software, which identifies common points or features in the images. The software then triangulates the measurements between these points to calculate the spatial coordinates of the objects or features. By utilizing the principles of stereoscopy and trigonometry, photogrammetries can accurately reconstruct the shape, size, and position of the objects or terrain.
Photogrammetries find applications in various fields, such as urban planning, archaeology, engineering, and forestry. It allows professionals to create detailed topographic maps, digital surface models, orthophotos, and volumetric calculations. It is particularly useful in cases where direct measurements are difficult or dangerous, or when capturing a large area is required.
Advancements in technology, such as digital cameras and high-resolution aerial imagery, have greatly enhanced the accuracy and efficiency of photogrammetries. Additionally, the integration of photogrammetric data with other remote sensing technologies like LiDAR (Light Detection and Ranging) has further expanded its capabilities, enabling more detailed analysis and visualization of spatial data.

Etymology of PHOTOGRAMMETRIES
The word "photogrammetry" is derived from two Greek words: "photos" meaning "light" and "graphein" meaning "to write" or "to draw". When combined, it refers to the art and science of making measurements and creating maps or drawings using photographs, specifically by analyzing the geometric properties of objects or scenes captured in those photographs. The term "photogrammetries" is the plural form of "photogrammetry".
