Photogrammetry is the creation of maps from digital aerial photographs which have been made with special high-resolution cameras.
How does Drone Photogrammetry work?
By attaching lightweight photo cameras to drones, high-resolution digital 3D aerial photos can be generated, which can then be processed with special software.
This technology can be used for many different purposes:
creating maps
gathering geo-information
digital aerial photographs
digital orthophotographs
3D relief models
high density point clouds
ortho mosaics
Application
These 3D spatial data of (objects on) the earth's surface can be used to calculate distances, surfaces and volumes. The current technology allows us to make elevation models with a resolution and vertical precision of better than a few centimeters.
