The two-day course will enable you to maximise the value of the data collected by your drone. It will also cover flight planning for optimum coverage, and processing techniques to ensure the accuracy and utility of data captured. Having the best understanding of capturing the data will increase the use of your flight time. Led by highly experienced SUA Operators, candidates will explore the art of the possible, using theory, workflows and case studies
Candidates who are interested in a broader scope of close range photogrammetry or require practical flying tuition can contact our team to discuss further.
Having the ability to capture images and turn it into meaningful data is key!

The Aerial Surveying course will cover:
Digital imaging – The quality of the raw data is fundamental to a successful project. This section will focus on the requirements for producing the highest quality imagery and will include discussion on camera settings, lenses, field of view, resolution, distortion, ground sampling distance (GSD), coverage/overlap and photo-control.
Photogrammetry theory and practice – A brief background to place today’s advances in context and a little theory to explain how the process works are the subjects of this session. It will include an explanation of the perspective effect of a camera’s central projection and how 3D data is produced from an orientated and overlapping series of 2D images both for stereo mapping and the modern multi-image software products
Workflow and outputs – With the emphasis on flight planning, field checking and quality control at each stage of the process the survey outputs available to the SUA user will be explained. These include photogrammetric point clouds, triangular surface meshes, textured 3D models, raster digital elevation models for GIS, orthophotography and 3D vector data collection
Software demonstration and case studies – Active demonstration of parts of the workflow using one or more software suites will help to crystallise the information learnt from the previous sessions. It will include a discussion of the settings available to improve the output, observation of control points for geo-referencing and a brief look at vector data collection in 3D. Case studies will be shown, some of which may stray outside of the SUA realm to demonstrate the flexibility of photogrammetry in supplementing the airborne data using terrestrial imagery.
