Quarries and mines
Drone photogrammetry can provide instrumental changes to the accuracy and cost-efficiency of survey models within quarries and mines. Utilising RTK and PPK processing provides the same level of positioning accuracy as traditional survey methods while completely solving the safety issues that human surveyors face.
Drone photogrammetry in quarries and mines allows for:
- Efficient and precise stockpile and highwall volume measurement, analysis and management. Using drones instead of traditional methods enable more convenient, faster, easier and safer surveys
- Checking whether berms, toes and crests are at the proper mine safety and health administration levels without requiring a person to be on site
- Surveying and analysing areas and locations unreachable by humans
Terrain modelling is crucial to understanding the grounding before and during a project. Drones can precisely capture digital elevation models, digital surface models and digital terrain models through their agility of flight and computer processing capabilities.
Drones can slash the impractical costs of helicopters while offering incredible benefits that other methods cannot even achieve. Drones reach further locations, are easy to control, responsive and collect accurate data and information through the required terrain region.
Digital Elevation Models (DEMs)
Drones can capture the elevation of the terrain and transfer the data to accurate 3D terrain models without natural and built features. Drone DEMs benefit engineers and surveyors for infrastructural project management, hydrology, flow direction studies, soil science, land-use planning, glacier monitoring, avalanche risk mapping and terrain stability, among others.
Digital Terrain Models (DTMs)
We develop DTMs composed of vector data sets to capture natural features such as ridges, rivers and break lines.
Digital Surface Models (DSMs)
Terrain mapping can produce DSMs that represent the environment including all the natural and built features. Drone modelling can create DSMs for urban planners, construction projects, vegetation management projects, aviation and airport analysis, wireless communications and many other industries that evaluate how terrain and features interact.
Aerial photogrammetry and LIDAR can immediately materialise precise 3D models of existing infrastructure and terrain. With appropriate technology, drone applications create models with precision within a centimetre tolerance, outshining traditional models in all categories, including cost, efficiency, accuracy and safety.
Drones can be used to evaluate rail surveys down to an accuracy that can replace laser scanning, making the process much faster, safer and cheaper. Other existing infrastructure can benefit from drone modelling by gathering data from previously unattainable angles and positions and studying the movement of structures and terrain over time.
