Precision Aerial Data for Engineering and Planning
Centimetre-accurate 2D maps, 3D terrain models, and volumetric data delivered within 48 hours.
Survey-Grade Accuracy
Aerial Mapping That Meets Engineering Standards
DroneMaster's mapping and surveying service combines cutting-edge photogrammetry software — including Pix4D and DJI Terra — with rigorous field methodology to produce deliverables that meet or exceed the accuracy requirements of engineering, planning, and environmental projects.
We establish Ground Control Points (GCPs) across every survey site using RTK GNSS positioning, ensuring that derived datasets are tied to recognised coordinate systems including OSGB36 and ETRS89. GCP placement is the cornerstone of survey-grade photogrammetry: without it, drone maps can exhibit systematic height and position errors that make them unsuitable for professional use. DroneMaster never cuts corners on this critical step.
Our processed datasets integrate directly into the tools your team already uses. Orthomosaics open natively in QGIS and ArcGIS; point clouds load into AutoCAD Civil 3D and Bentley ContextCapture; surface models are BIM-compatible and can be delivered in formats ready for Revit or Navisworks workflows. Whether your project demands a rapid site overview or a centimetre-accurate topographic survey for structural design, our data pipeline delivers.
All surveys are planned and executed by qualified drone pilots with formal surveying knowledge, ensuring that flight altitude, overlap settings, and GCP distribution are optimised for the accuracy and resolution your project demands.
Deliverables
Data Products
Every survey produces a suite of georeferenced outputs suited to different professional workflows. Choose the products you need or commission a full dataset.
Orthomosaic Map
A georeferenced, photogrammetrically corrected 2D top-view image of the survey area. Each pixel is assigned a real-world coordinate, giving you a true planimetric representation suitable for measurements, overlays, and GIS import. Delivered as a high-resolution GeoTIFF with embedded projection metadata.
Digital Elevation Model
DEM and DSM (Digital Surface Model) rasters represent surface height data across the survey area. The DSM captures the top of all visible features including vegetation and structures; the DEM models the bare-earth terrain beneath. Essential for drainage analysis, cut and fill planning, and flood risk assessment.
Point Cloud
A dense 3D point cloud in industry-standard LAS or LAZ format, each point carrying XYZ coordinates, RGB colour values, and classification data. Point clouds are the foundation for all 3D modelling workflows, structural assessments, and volume calculations. Fully compatible with CloudCompare, Recap, and Civil 3D.
Contour Map
Vector contour lines generated at user-specified intervals from 5 cm to 1 m, depending on terrain complexity and accuracy requirements. Delivered in DXF or SHP format for direct import into AutoCAD, MicroStation, and GIS platforms. Ideal for topographic drawings, planning submissions, and civil engineering design.
Volume Calculation
Accurate cut and fill volumes and stockpile measurements derived from the 3D surface model using base-plane or triangulation methods. We provide a written summary report with volume figures in cubic metres, annotated maps showing measurement zones, and the underlying surface data for audit purposes.

Quality Assurance
Accuracy & Standards
With properly established Ground Control Points and RTK GNSS positioning, DroneMaster surveys consistently achieve 2–3 cm horizontal accuracy and 3–5 cm vertical accuracy across open terrain. These figures align with RICS guidance for topographic surveys and are suitable as primary survey data for planning applications, boundary disputes, and structural engineering briefs.
All projects are delivered in the coordinate system specified by the client. We support OSGB36 (British National Grid, EPSG 27700) for most UK work and ETRS89 (EPSG 4258) for projects requiring pan-European compatibility. Vertical datums are referenced to Ordnance Datum Newlyn (ODN) unless otherwise instructed.
Deliverable formats are chosen for maximum compatibility with the client's workflow: GeoTIFF and ECW for raster data; LAS and LAZ for point clouds; SHP, GeoJSON, and DXF for vector data; PDF and DWG for drawing outputs. Every project includes a survey report documenting the methodology, GCP coordinates, achieved accuracy, and software version used for full audit traceability.
