Photogrammetry turns 2D data back into 3D representations of the real world it represents.
Photogrammetry is the science of combining photographic images together with geospatial information to create a 3D model of an area or object. This 3D model can be combined with other data from sensors including GPS location data, LiDAR, multispectral, or thermal imaging, a fusion of data that can be used to measure physical spaces, gauge large distances, or understand structures.
Photogrammetry can be used to create 3D models of any three-dimensional aspect of the world, including land, infrastructure, statues, buildings, and spaces large and small.
Capturing data about 3D objects using drone-mounted sensors creates 2D information about the 3D world. Photogrammetry turns 2D data that represents 3D objects into digital 3D representations. These are called digital twins—digital replicas of items in the real world represented in software.
Digital twins come in the form of 3D models using point clouds, digital meshes, digital elevation models, and orthomosaic images.
