3D Mapping

Definition

3D mapping is the process of creating a three-dimensional representation of a physical space or object using specialized software and data from various sources, such as drones, sensors, and cameras. This technique allows for enhanced visualization and analysis of spatial information, making it particularly valuable in fields like aerial cinematography and the use of drones.
