Satellite Image Processing and Analysis in the Big Data Era

Course content

We live in exciting times with a rapidly expanding number of earth observation products being available for better understanding global environmental and socio-economic changes. However, this development poses a number of challenges:

 

- How to process large remote sensing data sets efficiently?

- Which approaches are suitable for time-series analysis?

- How to extract and analyze patterns and trajectories of land change?

 

Through this course, the principles of big data analysis will be introduced, including cloud computation, API-driven image processing and specific image formats that are efficient to store and analyze large data sets. We will work with cloud-image processing platforms like Google Earth Engine, FAO Sepal to process and analyze various optical and microwave data sets. Specific attention will be on the use of very-high-resolution data for advanced machine-learning pattern recognition techniques, such as convolutional neural networks, and how to assess model performance and accuracy. Machine learning techniques (e.g., Boosted Regression Trees) using all sorts of geospatial data will be taught for understanding the drivers of environmental change. The course welcomes those who would like to advance their knowledge in remote sensing of the environment and socio-economic footprint, pattern recognition and spatial data analysis or apply gained skills in programming to remote sensing of the environment. It is expected the students will progress their scripting skills in Python/Javascript environment. At the same time, we also expect that students have prior experience in satellite image analysis.

  • Setting up and evaluation of machine-learning approaches in land-use modeling.
  • Integrating knowledge gained from lectures, hands-on exercises and independent readings of up-to-date publications to perform a course project of your choice.

 

Competencies:

  • Ability to process and analyze various types and a large amount of remote sensing data sets using advanced cloud-based methods and state-of-the-art machine learning.

The form of teaching is theory exercises combined with lectures and various forms of activation of learning. For the teaching plan, please see Absalon.

Please see Absalon course page.

BSc in Geography and Geoinformatics or equivalent. Prior experience in satellite remote sensing processing and analysis is expected. Experience in scripting is welcomed.

The course builds on prior knowledge of working with satellite imagery, such as passing via Bachelor level classes such as Introduction to Remote Sensing, Classification of Spatial Data, as well as some Master-level remote sensing classes, such as Remote Sensing of Geobiosphere, Remote Sensing in Land Science Studies, Spatial pattern analysis. However, we will try to accommodate the students without prior experience in remote sensing but with solid experience in programming. If you dit not take remote sensing classes, please contact the course responsible prior to enrolling in the class.
