Photogrammetry Drone Mapping Surveys

Accurate 3D modelling, site scanning and mapping using specialist drones

CAA Approved Drone Operators | Cyber Essentials Tier 1 Certified | ISO 9001:2015 Certified | CHAS Accredited

Photogrammetry drone surveys for aerial mapping and 3D modelling.

Drones allow for the quick and efficient scanning of land, ground formations and heritage sites. Our 3D models can be used to accurately map boundaries, monitor land and create topographic maps.

Using specialist drones, we’re able to create accurate 3D models to monitor construction and manage site stock as part of BIM (Building Information Modelling). We have a large fleet of aerial platforms, ranging from DJI Enterprise drones to bespoke systems specifically created by our technical team for individual projects.

To capture reliable data on-site, we only use the highest-resolution visual cameras available to the commercial market. This varies from 36 megapixels to 400 megapixels, depending on a project’s requirements.

How can we help?

  • Create land registry maps

  • Accurately measure buildings and environments

  • Assess rock and ground formations

  • Map and model heritage sites

  • Map and definite accurate field boundaries

  • Measure, manage and monitor site stock


Our 3D drone mapping surveys provide clients with an aerial view of their site.

About Photogrammetry

Measure from aerial drone images.

Photogrammetry is the practice of capturing 2D images and converting them into 3D models. Used for surveying and mapping, photogrammetry surveys allow for accurate measurement between objects. This is ideal for:
  • Creating land registry maps
  • Accurately measuring buildings
  • Monitoring rock and ground formations
  • Mapping and modelling heritage sites
  • Mapping accurate field boundaries
  • Measuring, managing and monitoring site stock

Photogrammetry Case Study

Our drone operators follow strict workflows to capture quality data on-site.
A basic photogrammetry survey has 4 stages, which are detailed below.

As soon as a brief has been set by a client, our engineers will begin planning the project for all aspects of safety. This includes:

  • Checking and verifying site suitability
  • Obtaining permissions for drone operations
  • Planning ground control points for accurate data collection
  • Establishing a ground-based approach for data collection (if required)

Our CAA Approved drone operators will then use flight-planning software to map out a site flight-path.

After arriving on site, our team will setup a monitoring station to conduct operations from. The station will enable our pilots to monitor the quality of data captured during flight. It also allows for light processing on-site for data validation.

Once complete, our pilots will setup and deploy a specialist drone. Equipped with a high-resolution sensor, the drone will begin capturing visual data for the entire site.

Using the data collected on site, our team will start to process the aerial images using specialist software. During the processing, an engineer will be on-hand to refine and optimise the quality of outputs. This ensures that high-quality orthomosiacs and photo-realisitic models are created.

Within 7-10 days* of survey completion, clients will receive:

  • A Project Summary
  • Project Object File (.obj)
  • Project Shape File (.shp)
  • Point-Cloud Files (.las, .laz)
  • High-Quality Visual Orthomosiac (.tiff)
  • Geographic Information System (.kml, .kmz)

Depending on requirements, we can also provide online viewing software for the final outputs.

CAA Approved Drone Operators

Our engineers are approved by the CAA to operate drones commercially (PfCO 2082). This enables us to capture external elevations from an aerial perspective.

We’re one of the few companies with a specialist Operating Safety Case in the UK. This means that we can fly closer to buildings and structures then standard operators (20m).

We help our customers save time and money.

Our engineers provide nationwide coverage for a wide range of inspection services.
