BENEFITS
Drone photogrammetry with RTK GNSS and GCPs delivers 2-5 cm GSD across open terrain and sites. LiDAR adds accurate bare-earth elevation models where vegetation or surface obstacles block photogrammetry.
A single drone mission covers hundreds of hectares per flight day, delivering orthomosaic and elevation data for large sites and corridors faster than ground survey to accelerate project decisions.
All drone survey flights require GACA Part 107 authorization. Terra Drone Arabia holds active certification and manages flight permits directly before deployment so clients face zero regulatory friction.
Deliverables are formatted for direct import into AutoCAD, Civil 3D, ArcGIS, QGIS, and BIM platforms without extra processing. Orthomosaics, DTMs, and point clouds are structured for immediate workflow use.
Aerial data is processed in-house via Terra Mapper for direct accuracy control, point cloud classification, and fast deliverable generation with no third-party bottlenecks or format conversion delays.
Drone survey and mapping missions delivered for residential developments, land and aerial surveys, water infrastructure, municipal roads, Red Sea island projects, and marine programmes in Saudi Arabia.
CHALLENGES
Ground crews cover limited area per day. Surveying large sites conventionally takes weeks, delaying design freeze, earthworks approvals, and procurement decisions that depend on accurate base data.
Steep slopes, quarry faces, wadis, and remote desert are unsafe or unreachable for ground crews. Leaving them unmapped creates data gaps affecting volume calculations and access road planning.
Standard handheld GPS delivers meter-level accuracy, failing engineering sign-off requirements. Drone photogrammetry with RTK GNSS and GCPs achieves sub-5 cm accuracy needed for cut-fill design.
Without regular aerial surveys tied to one datum, tracking progress against design causes disputes. Periodic drone mapping provides an objective, timestamped progress record for all project stakeholders.
Slow survey campaigns deliver data long after design decisions are forced onto assumptions. In-house drone processing with Terra Mapper compresses the cycle from flight to ready deliverables down to days.
Hiring separate firms for drone capture and ground control causes mismatched coordinates, double mobilization, and formatting friction. Combining both under one team eliminates alignment issues entirely.
TECHNIQUES & METHODS
Aerial imagery captured via high-resolution enterprise photogrammetry sensors processed into orthophotos, DSM, DTM, and 2D CAD data. RTK GNSS with GCPs achieves sub-5 cm accuracy at 2-5 cm GSD.
Airborne LiDAR sensors capture dense point clouds for bare-earth DTMs in vegetated terrain and wadis, producing classified point clouds and contour data.
Drone survey data processed in-house generates detailed 3D point clouds, DTMs, and meshes for asset management. Enables BIM clash detection, as-built verification, and progress monitoring.
Repeat drone flights at project milestones compare as-built conditions against design baselines and track volumetric earthworks. Each flight delivers timestamped orthomosaics and progress reports.
DELIVERABLES
PLATFORMS & APPLICATIONS
Pre-design base surveys, progress monitoring, cut-fill earthworks documentation, and as-built verification for roads, utilities, and construction projects across Saudi Arabia.
Stockpile volumetric surveys, pit boundary mapping, slope monitoring, and access road survey for mining operations. Drone photogrammetry and LiDAR inspect open-pit terrain safely from altitude.
City-scale aerial mapping for land use analysis, parcel demarcation, and GIS integration on urban projects. Drone photogrammetry delivers orthomosaics and DTMs for smart city digital twins.
Site prep surveys, pipeline and facility mapping, and access road survey for onshore projects. See our Oil & Gas industry page for details.
