THE COURSE

DRONE SURVEY FUNDAMENTALS

This course is aimed at sharing with you the theoretical and practical knowledge required to be able to carry out accurate drone surveys consistently. It focusses on gaining a deep understanding of the fundamental principles behind photogrammetry, LiDAR, GPS and geomatics.

Some of the questions and issues that we will look at are:

  • Why can you not use a 50mm lens on a full frame camera for photogrammetry if you want accurate results.
  • What is the difference between RTK and PPK GNSS positioning?
  • Why is the measured terrain height usually twice as inaccurate as the horizontal measurements?
  • What is the relationship between UTM and WGS84?
  • Why do I need to know about spheroids, ellipsoids and geoids?
  • Should I use ground control points even if I use a drone with RTK positioning?
  • How far apart should these ground control points be placed?
  • How do you calculate the resolution or ground sample distance for a photogrammetry survey?
  • What are the points that I should not compromise on when buying a drone?

What we will not cover in this course is how to fly a drone. There are hundreds of drone schools across the globe that will teach you this aspect. What we will cover are those items that you absolutely need to know to be an aerial surveyor. This knowledge will save you valuable time in not having to redo a survey because you made the same beginners mistakes that everyone did. Or that will prevent you from disappointing your customer as you promised something that can’t be delivered.

This course is packed with both the theoretical knowledge and practical tips gained over decades of aerial surveying. I can share that knowledge with you and will elevate you to the same level of expertise as your customer and this will set you apart from most of your competitors.

NB Note that all course material such as the book and presentations are in English! The course can be Dutch spoken if all attendees speak Dutch.

COURSE OUTLINE

The course itself is made up of five separate sections each handling a separate subject.

In section 1 we will cover basic geodesy such as coordinate systems, some fundamental calculations, vertical reference levels, geoids, spheroids, map projections, accuracies, precision, standard deviation and resolution.

In section 2 we will look at satellite positioning. Satellite positioning, also referred to as GNSS and not to be confused with GPS, is the backbone of almost all aerial survey operations. We will look at how GNSS works, the sources of error and methods to eliminate the most common errors and methods to augment the accuracy of GNSS.

In Section 3 we study in depth the two most common methods of aerial surveying with a drone, namely photogrammetry and LiDAR. We will focus on how exactly this works, what accuracies can be obtained, how you can predict these accuracies and what to look out for when you purchase a drone, a camera and or a LiDAR system.

Section 4 will cover all you need to know about the different types of data and end products that are created with drones. You will learn the difference between vector and raster data sets and how these data sets are created.

Finally, in section 5 we will concentrate on the more practical side of aerial surveying with a drone. On one hand we will look at some real live cases and discuss the choices made and the reasoning behind these, we will look at data processing and finally also at some competing technologies.

The course is a three-day classroom training. Each student will receive the drone survey fundamentals course book. This book is over 150 pages and packed with all the covered material. This book is not for sale separately and only available to course participants. In addition, each successful student will receive a certificate at the end of this course.
