Course Outline

The course offers a combination of background information and hands-on experience using a variety of functions presented by GNSS technology. The material is presented using a combination of Power Point presentation, discussions and practical workshops to capture the individual learning preferences of the participants.

1.    Coordinate System

To make any sense of the GNSS technology in use, an understanding of various coordinate systems is necessary. For example, what is WGS84 of ERTF89 and how does this relate to National Grid or any other map projection? Why do we have map projections anyway? These are some of the questions that will be answered in a simple to understand way.

2.    How does it work?

Here we go slightly beyond the “switching on of the Receiver” process and provide some background information on how the system works using GPS as the guiding technology. Once those workings become clear it is a simple step towards understanding certain operations and settings that are necessary to obtain the correct answers from the system.

3.    Kinematic Surveys

In this part we look more closely at the available Controller software and how to use the various functions. This part is mostly practical: exploring, using the example of Network RTK, how to carry out a Site Calibration or Localisation; how to perform a topographic survey and how to use the setting out functions. Performing Post Processing Kinematic surveys will also be covered.

4.    Static Surveys and Post Processing

A brief look at some processing software will enable the participants to download and process survey data, create files for uploading setting out data to the controller and briefly explore the static processing capability of the office software.

At the end of the course participants will receive all course material in a folder together with a certificate of completion.

Do you want to know how to plan, take and process high quality images to create accurate and detailed 3D models?

This three-day course covers photogrammetric techniques from both a theoretical and practical aspect. Led by a highly experienced tutor, in a small group setting, it provides teaching in the use of cameras and a hands-on processing experience. A high level of tutor/student interaction is possible as this course is never run with more than 6 delegates.

Those who are interested in how to maximise data collected from a small unmanned aircraft (SUA) should consider the two-day SUA Photogrammetry Course. This course contains no practical sessions but is packed with tips, advice and demonstrations on how to best exploit the imagery collected from the air.

Course Summary

Photogrammetry has undergone something of a renaissance in recent years resulting in TSA’s decision to run a quarterly short course on the topic. The demand for the course has arisen because of the recent introduction of more user friendly and semi-automated methods developed via a combination of computer vision algorithms and conventional photogrammetry.

The application of the new techniques has grown enormously due to:

  • the low investment costs,
  • general familiarity with photography,
  • the increasing interest in the provision of 3D metric data for archaeological, architectural and engineering purposes and
  • the use of small unmanned aircraft (SUAs) for survey and reconnaissance work.

The new technique uses image matching methods and off-the-shelf cameras for the production of geo-referenced point clouds that can be favourably compared to those produced by laser scanners. The use of SUAs for aerial survey of smaller sites is a fraction of the cost of conventional aircraft and the newer algorithms are perfect for the analysis of the many smaller and more randomly distributed images taken on an SUA project.

  • photographic methods and other field considerations
  • conventional photogrammetry theory and applications
  • plane and ortho rectification of imagery
  • user orientated techniques now available in lower cost software (eg EOS Photomodeler Scanner, Bentley ContextCapture and Agisoft Photoscan) and their application
  • the advantages and disadvantages compared to laser scanning
  • specifying and commissioning projects
  • case studies

The course extends over three days and includes six sessions of 2.5 hours each.

Do you want to know how to plan and process your SUA (Small Unmanned Aircraft)/drone imagery to obtain quality survey output and a professional edge for your business and clients?

This two-day course is packed with advice on how to maximise the impact of data collected by your SUA. It will cover flight planning for optimum coverage and processing hints to ensure accurate data delivery. Led by a highly experienced tutor, students will explore the art of the possible using theory, workflows and case studies.

This course is lecture room based but with a maximum of twelve students to maintain a level of intimacy and interaction. It involves a mixture of presentations and software demonstrations.

Delegates who are interested in a broader scope to include terrestrial imagery and require hands-on experience of using cameras and photogrammetry software should attend the three-day Photogrammetry and Digital Imaging Course.

Course Summary

The use of SUA (Small Unmanned Aircraft) to collect data has rapidly increased in the last few years. Not only surveyors but engineers, archaeologists, environmentalists, conservationists and numerous other disciplines are exploiting the advantage of data collected by a small, agile, airborne platform.

Using SUAs for the aerial survey of smaller sites is a fraction of the cost of conventional aircraft and the newer software algorithms are perfect for the analysis of the many smaller and more randomly distributed images taken on an SUA project.

The course, which is new to the TSA Survey School in 2019, covers:

  • 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.

The course extends over two days and includes four sessions of 2.5 hours each.
