Remote Sensing: Advanced

Up from the next start (July 6th, 2026), this module will be offered with 6 ECTS credits.

In this module, you will discover how advanced remote sensing turns rich Earth observation data into meaningful environmental insight. Moving beyond basic image interpretation, the course explores how we can describe, analyse, and understand the Earth through its spectral, thermal, structural, and temporal signals.

Along the way, you will engage with topics such as feature engineering, hyperspectral and thermal remote sensing, microwave remote sensing, object-based image analysis, and time series analysis. The module also introduces big data concepts, machine learning foundations, neural networks and foundation models, as well as questions of uncertainty, advanced validation, and the ethical and economic implications of AI. These perspectives offer a forward-looking view of remote sensing as a field that is becoming increasingly data-rich, automated, and interdisciplinary.

By the end of this module, you will have developed a broad understanding of advanced remote sensing approaches and their role in Earth observation. The goal is not just to understand the methods, but to be able to think critically about when and why they work, and where they fall short. This includes:

  • explaining the principles of advanced feature extraction and representation of Earth observation data
  • understanding the added value of hyperspectral, thermal, and microwave remote sensing for environmental analysis
  • describing how spatial context, objects, and temporal dynamics can be analysed in Earth observation data
  • understanding how large and heterogeneous Earth observation datasets can be organised and analysed
  • explaining the foundations of machine learning and neural networks in remote sensing
  • describing the potential and limitations of recent AI developments, including foundation models
  • assessing the importance of uncertainty, validation, and robustness in remote sensing workflows
  • critically reflecting on the ethical and economic implications of AI-based Earth observation

Remote Sensing: Basics module or comparable knowledge. Basic skills in Python and/or R are also recommended.

We would like to inform you that this is an exclusively English language module, hence any kind of communication with the module lecturer should be in English. A discussion forum is maintained in moodle in order to support efficient module instruction. You are requested to submit all your questions related to this module to this forum only. The lecturer will check all incoming comments on a regular basis. She will answer your questions or provide you with pointers for solving your problems. The module is delivered in form of an instructed self-study that is based on explorative learning process. Theoretical concepts are complemented with practice-oriented examples demonstrated with help of multimedia elements. Upon completion of the module students are requested to evaluate the module, which is a part of our quality assurance policy and practice.

  • QGIS + EnMAP plugin
  • SNAP
  • eCognition
  • Jupyter Notebook

The software used in this module runs well on a standard laptop. A multi-core CPU, 8–16 GB RAM, and enough free storage space are generally sufficient; no specialised hardware is needed.

Please contact UNIGIS.office@plus.ac.at if you have further questions on system requirements.

The assessment is based on your completed assignments. They must be submitted in written format to the Dropbox within the required time period. If assignments are submitted late, the lecturer is not obligated to grade them.
