Orthophotography
2D and 3D mapping, orthophotography, volumetrics and 3D modelling by drone. Up-to-date, georeferenced and renewable data for mining, quarries and land management.
Mapping, whether in two or three dimensions (elevation perspective), helps understand the environment and assess impacts. We provide up-to-date, renewable mapping on demand. We can also produce full 3D models of your infrastructure — for promotion, planning or asset and equipment documentation.
Photogrammetry
What is photogrammetry used for?
Photogrammetry is a technique for determining the dimensions and volumes of objects or spaces from aerial photographs. It involves a series of 3D captures from different viewpoints to obtain a relief projection of the scanned area. Using a drone makes it possible to produce a large volume of georeferenced 3D data in a short time with complex shooting options. This technology is useful in many fields: project owners for an overview of an area or site before work, urban planning and any infrastructure requiring a detailed general view.
Orthophotography
What is orthophotography?
Orthophotography is a derivative of photogrammetry consisting of assembling images to produce an accurate view of a large geographic area. This output is obtained using multiple high-resolution aerial images taken by our drones. Assembling these images creates a plan that is both extensive (several hectares at once) and detailed. The images are georeferenced and can be overlaid on a map or GIS (Geographic Information System) plan.
Volumetrics
Why volumetrics?
Volumetrics is an application of photogrammetry that creates a 3D model of terrain or stored volumes. This technique is mainly used in mining, power plants, quarries or land management. Similar to 3D modelling, it extracts volumes (volumetric measurement of materials) and tonnages from a defined space. Using a drone allows this work to be done regularly thanks to its speed and low cost. Data collected when mapping a site can also be used for volumetric surveys (e.g. quantities of material removed between two surveys).
3D modelling
3D modelling
One use of photogrammetry is 3D modelling. After taking aerial photographs, this technique uses suitable software to produce synthetic images representing the photographed scene in three dimensions. 3D modelling provides a study base depending on what is needed:
- Evolution of relief (crevasses, cliffs…)
- Layout of a space (e.g. a road, building, park)
- Creation of an interactive model of a building, façade or monument
- 3D modelling of a structure
