Topography Mapping
Sub-5cm digital elevation models with RTK-corrected GNSS — bringing inaccessible terrain to the geologist's desk as navigable, measurable, drawable 3D models.
Bring the Mountain to the Desk
Topographic surveys of the Kingdom's most mineral-rich terrain often require weeks of foot access — assuming the terrain is walkable at all. Air Solutions replaces that effort with autonomous aerial photogrammetry: a centimeter-precise 3D reconstruction the geologist navigates, measures, and digitizes from the office.
At each waypoint the drone captures five photographs at different angles with 80% frontal and 70% lateral overlap. Photogrammetry software identifies common points across hundreds of frames and reconstructs both surface relief and texture — producing a 3D model accurate to within centimeters of ground truth.
Deliverables open in CloudCompare, ArcGIS, and QGIS — the geologist's existing toolset. No drone training, no photogrammetry expertise required. The terrain becomes a navigable artifact: zoom into a rock face, measure a fault offset, draw a lithological contact line, all from a workstation.
From Brief to Drawable Map in 24–33 Days
Planning
Client provides geolocated boundary, target precision, and area-of-interest. Flight plan generated and airspace coordination completed.
Image Acquisition
Autonomous flight along pre-calculated grid. Five photos per waypoint at multi-angle capture, 80%/70% overlap maintained throughout.
Image Processing
Photogrammetry pipeline: photo alignment, dense point cloud, mesh generation, orthomosaic, DTM extraction. Several days of compute.
QA / QC
Ground control point verification, vertical accuracy check against RTK measurements, gap-filling and tile reconciliation.
Delivery
OBJ/FBX 3D model, GeoTIFF orthomosaic, LAS/LAZ point cloud, GeoTIFF DTM — handed off in formats native to ArcGIS, QGIS, CloudCompare.
Coverage of Type 3 Inaccessible Terrain
100 km² of mountainous terrain mapped per month — fully drawable from the geologist's office.
