Aerial data capture and mapping
Every geospatial project starts with good data. We survey sites to centimetre-level accuracy using drone photogrammetry and RTK/PPK positioning, and deliver processing-ready orthomosaics, maps, elevation models and point clouds.
What’s included
- Drone photogrammetry
- Drone mapping
- RTK / PPK surveying
- Orthomosaics
- Topographic mapping
- Existing conditions surveys
- DSM / DTM / DEM
- Contours
- 3D point clouds
- Volumetrics and stockpiles
- Cross-sections and profiles
- High-accuracy land surveys
Why use drones
Drones cover large sites far faster than a ground crew, with consistent accuracy and a full visual record. A single flight produces an orthomosaic, an elevation model and a point cloud — one dataset, many deliverables.
How we achieve accuracy
Ground sampling distance (GSD) is driven by flight altitude and the camera; absolute accuracy by ground control points and RTK/PPK. Horizontal and vertical errors are reported against independent checkpoints.
A foundation for everything downstream
The same data feeds 3D modelling, GIS analysis, AI object detection and change monitoring, so new questions rarely mean another site visit.
Deliverables from this service
Orthomosaic
A georeferenced, distortion-corrected aerial image mosaic you can measure directly from.
GeoTIFF, ECW, JPEG 2000Topographic survey
A layered, scaled digital survey to Turkish large-scale mapping standards, with spot heights, contours, buildings and site features.
DWG, DXF, NCZ3D terrain model
A 3D model of the ground and everything on it — surface model (DSM), bare-earth model (DTM), classified point cloud and textured mesh.
GeoTIFF (DSM/DTM), LAS/LAZ, OBJ, 3D TilesEarthworks & volumes
Cut and fill volumes from the difference between existing ground and the design surface, with cross-sections, schedules and a checked and approved report.
PDF report, DWG sections, XLSXIndustries we serve with it
Mining
In mining, production, inventory and safety all come down to the ground. By surveying pits, benches and stockpiles regularly, we reconcile production by volume and keep track of slope geometry.
Disaster response and damage assessment
In the first hours after a disaster, an accurate, up-to-date map is critical. We map the affected area quickly, identify damage through before/after comparison, and provide a base for reconstruction.
FAQs
How accurate is drone mapping?
With ground control and RTK/PPK, we target centimetre-level accuracy. The achieved figures are stated in the accuracy report, measured against checkpoints.
What’s the difference between a DSM, a DTM and a DEM?
A DSM captures the top surface, including buildings and vegetation; a DTM represents bare earth only. DEM is the umbrella term and is often used interchangeably with DTM.
How large a site can you survey?
Anything from a small plot to sites of several hundred hectares. Larger sites are split into blocks and flown over multiple days.
