Mapping and Modelling
Photogrammetry is the use of captured images to create accurate 2D maps and 3D models of a building or location. These can then be used for the purposes of planning, inspection, reporting, promotion, or documentation.
3D models
With a 3D model of a building or site, measurements can be taken, not just of distances and sizes, but also the volume of material stockpiles. These measurements can be compared over time.
