Drone Photogrammetry Survey & 3D Slope Modelling

DCC uses high-resolution drone photogrammetry to collect overlapping imagery from rock slopes and difficult-to-access areas. The imagery is processed into georeferenced orthomosaics, 3D point clouds, surface models and measurable cross-sections to support geological mapping, slope-geometry assessment, quantity calculations, stabilization design and as-built documentation. Accuracy is verified against approved survey control where required.

In complex mountainous terrain across the UAE, manual surveying on steep rock faces presents significant safety risks and line-of-sight limitations. DCC overcomes these challenges through structured drone flight planning, ground control point (GCP) referencing, and high-resolution optical sensors. Our photogrammetric workflows generate 3D slope reconstructions that enable virtual discontinuity mapping (dip, dip-direction, joint spacing, and persistence) on previously inaccessible cliffs. In addition, 3D point cloud comparison enables accurate earthwork volume verification, cut-fill quantity audits, overbreak assessment, and structural surface comparisons over time.
