Managing water quality is a great challenge simply because many factors are contributing; the way we use water, practices that threaten water quality, the different pollutants and their sources and the forcing hydrology. Knowing the processes of these factors affecting water quality is not sufficient. It is essential to monitor these factors to understand how they combine and interact for different regions. 

Current monitoring practices by water managers depend largely on labour-intensive measurements, which provide only a limited insight into the spatial and temporal distributions. On the other hand, Earth Observation technology offers a significant benefit due to its synoptic coverage and repeated surveillance. However, the added value of Earth Observation data is determined, primarily, by the ability to convert these data into accurate information on water quality variables. 

This course will increase your knowledge and technical skills in using Earth Observation data to derive water quality indicators and assess their accuracy.

For whom is this course relevant?

Tertiary: at graduate and post-graduate levels.

What is the course content?

The course builds upon the quartile one, the core modules, of the Master's  Geo-information Science and Earth Observation and the Water Resources and Environmental Management 2.0 courses and contains four interwoven learning modules. The first three learning modules form the centre of this course, whereas the last module comprises a closure to this course:

  1. Basic principles of Remote Sensing of water quality
  2. Earth Observation data access and handling
  3. Earth Observation-based water quality mapping with 2SeaColor
  4. Challenge is a case study whereby the participants apply the newly gained knowledge and integrate different Earth Observation data to produce water quality maps of areas of interest.

What is the programme structure?

The teaching method is based on learning-by-doing and practice. Sets of exercises, therefore, support each lecture. There are two types of activity in this course:

  1. Learning-by-doing exercises: these exercises are paper-based, whereby the participants can enhance the learning experience of the physical concepts, e.g., solve simple problems or derive a value by applying sets of equations. In this respect, these exercises are embedded in the lecture.
  2. Skill development exercises: these exercises used python codes in the JNB environment. They focus on providing the participant with the competency to address a real-world problem, for example, using Sentinel 2 images to derive water quality variables in lakes and coastal water.

What will be achieved?

After completing this course your will be able to: 

Why this course?

Do you want to develop the skills necessary to use satellite data to detect water pollution and monitor water quality? Then, this online course is what you need.

The high-level video lectures, self-study, quizzes and online discussions allow for an enjoyable online social experience. Live-streamed talks and visualised tutorials using state-of-the-art analysis tools will give you the skills to complete your learning experience on real-life study cases.

Career perspectives

Acquire the skills to use Earth Observation data to monitor water quality and detect pollution in coastal and inland waters.

Online learning, what is it like?

The course offers: 

  1. High-level video lectures, self-study, quizzes and online discussions
  2. Live-streamed talks and visualised tutorials using state-of-the-art analysis tools.

In this respect, the course is mainly based on self-study and attending the discussion sessions, with an expected study load of about 4 to 6 hours a week.

About your Diploma

Upon successful completion of this course you will receive a Certificate which will include the name of the course.

Along with your Certificate you will receive a Course Record providing all the subjects studied as part of the course. It states: the course code, subject, ECTS credits, exam date, location and the mark awarded.

If you decide to follow a full Postgraduate or Master's course at ITC, and after approval of the Examination Board, you will be exempted from the course(s) you followed successfully as an online course.

Admission requirements

Academic level and background

Applicants for an online course should have a Bachelor degree or equivalent from a recognised university in a discipline related to the course, preferably combined with working experience in a relevant field.


The faculty accepts transcripts, degrees and diplomas in the following languages: Dutch, English, German, French and Spanish. It is at the discretion of the faculty to require additional English translations of all documents in other languages as well.

Language skills

Success in your studies requires a high level of English proficiency. Therefore, prospective students with an international (other than Dutch) degree must meet the English language requirement. As proof that you meet this requirement, you will be asked in the application procedure to upload one of the requested language certificates:

Only these internationally recognised test results are accepted. Without a valid certificate, we cannot process your application.  

Other requirements

You are exempted from the English language requirement if you hold:

Online English tests during COVID-19

We acknowledge the difficulties experienced worldwide in taking the compulsory language test, due to the Covid-19 situation. Alternative English tests can be:

Please note that other online English language tests (i.e. IELTS Indicator test, Cambridge online test, etc.) will not be accepted.

Computer skills

To follow online education you must have basic computer experience, regular access to internet, and e-mail. For some courses, additional computer skills are required (see description of specific course).

Technical requirements online education and assessment

For online education, we formulated guidelines to guarantee optimal performance. For online oral exams and proctoring during online assessments, the webcam and headset requirements need to be met.

GIS and remote sensing

Most online courses, except for the introductory course, require knowledge of, and skills in, working with GIS and/or digital image processing of remotely sensed data.

Candidates are asked to provide proof of identity during the registration process.
