Photogrammetry is the science of extracting accurate three-dimensional measurements of objects and surfaces from photographs. It involves analyzing photographs taken from different angles and using computer algorithms to reconstruct the shape and position of the objects in the images. This technique is commonly used in fields such as engineering, architecture, and mapping to create detailed 3D models of physical objects.
3D mapping refers to the process of creating a three-dimensional representation of a physical environment or object using specialized software, GPS technology, and/or sensors. This technology has a wide range of applications, including mapping terrains, creating digital models of buildings, and even creating immersive virtual reality experiences.
The process of 3D mapping typically involves collecting a large amount of data about the environment or object being mapped. This data is then processed and analyzed using special software to create a detailed and accurate 3D model. The resulting model can then be used for a variety of purposes, such as engineering and architectural design, urban planning, and even video game development.
3D mapping has a number of advantages over traditional 2D mapping methods. For one, it provides a much more detailed and accurate representation of the environment being mapped. This can be useful in a variety of applications, such as disaster response and recovery efforts, where precise data can mean the difference between life and death.
