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 far faster than ground survey to accelerate project decisions.
Every drone survey flight requires GACA Part 107 authorization. Terra Drone Arabia holds active certification and secures flight permits directly before deployment, so you face zero regulatory friction.
Deliverables are formatted for direct import into AutoCAD, Civil 3D, ArcGIS, QGIS, and BIM platforms with no extra processing. Orthomosaics, DTMs, and point clouds are ready for immediate workflow use.
Aerial data is processed in-house via Terra Mapper for accuracy control and point cloud classification, visualized and managed in Terra MapX, then delivered securely to your team via Terra Cloud.
Drone survey and mapping delivered for residential developments, water infrastructure, municipal roads, highway corridors, slope and rockfall assessment, and Red Sea island and marine programmes.
CHALLENGES
Ground crews cover limited area per day. Surveying a site of hundreds of hectares conventionally takes weeks, delaying design freeze, earthworks approvals, and procurement decisions downstream.
Steep slopes, quarry faces, wadis, and remote desert are unsafe or unreachable for ground crews. Leaving them unmapped creates data gaps that distort volume calculations and access road planning.
Standard handheld GPS delivers meter-level accuracy that fails engineering sign-off requirements. Drone photogrammetry with RTK GNSS and GCPs achieves the sub-5 cm accuracy cut-fill design needs.
Without regular aerial surveys tied to one datum, tracking progress against design turns into dispute. Periodic drone mapping gives every stakeholder one objective, timestamped record of progress.
Slow survey campaigns deliver data long after design decisions are forced onto assumptions. In-house 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. Running both under one team removes alignment issues entirely.
TECHNIQUES & METHODS
Aerial imagery from high-resolution enterprise photogrammetry sensors is processed into orthophotos, DSM, DTM, and 2D CAD data via Terra Mapper, SimActive Correlator3D, and Agisoft Metashape at 2-5 cm GSD.
Airborne LiDAR sensors capture dense point clouds for bare-earth DTMs in vegetated terrain, wadis, and steep slopes where photogrammetry cannot see ground, producing classified clouds and contour data.
Drone survey data processed in-house generates detailed 3D point clouds, DTMs, and textured meshes that import directly into BIM and CAD environments for as-built verification and progress monitoring.
Repeat drone flights at project milestones compare as-built conditions against design baselines and track volumetric earthworks, delivering timestamped orthomosaics, cut-fill volumes, and progress reports.
Terra GeoAIX extracts kerbs, markings, and site assets across the dataset at +/-0.02 m boundary accuracy from a few operator-drawn examples, then detects change between survey dates for review before delivery.
DELIVERABLES
PLATFORMS & APPLICATIONS
Pre-design base surveys, progress monitoring, cut-fill earthworks documentation, and as-built verification for roads, utilities, bridges, 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 preparation surveys, pipeline corridor and facility mapping, tank farm documentation, and access road records for onshore oil, gas, and industrial projects across the Kingdom.
