NIGK22000U Satellite Image Processing and Analysis in the Big Data Era
MSc Programme in Geography and Geoinformatics
We live in exciting times with a rapidly expanding number of earth observation products available to understand global environmental and socio-economic changes. However, this development poses several challenges:
- How to process large remote sensing data sets?
- How to extract and analyze patterns and trajectories of land change?
Through this course, the principles of big data analysis will be introduced. This course emphasizes advanced machine- learning and pattern recognition, for instance, convolutional neural networks, random forests and other classification techniques. We will take a deep dive into how to evaluate machine learning models' performance and assess the accuracy of produced classification results. We will also work with Google Colab, PyTorch, Python-based libraries for GIS, and cloud-image processing platforms like Google Earth Engine to process and analyze various remote sensing data sets. The students are expected to progress their scripting skills in a Python/ Javascript environment.
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 and who would like to advance their skills in machine learning. However, this class is also open to those who already have skills in programming and machine learning, but seek to extend their portfolio in satellite remote sensing applications.
Knowledge:
- Sources of satellite data; currently operating non-commercial and commercial platforms in Earth Observation, with a specific focus on very-high-resolution imagery,
- Principles of pattern recognition, classification and segmentation using convolutional neural networks (CNNs),
- Advanced satellite image processing and classification in a cloud environment,
- Python Application Programming Interface (API); API-based computation with Python for big data processing.
Skills:
- Hands-on experience in parameterization, running and evaluation of the performance of convolutional neural networks for pattern recognition tasks using, e.g., Google Colab and PyTorch,
- Progression of skills in Python-based analysis of satellite data using machine learning,
- Ability to download, pre-process, and analyze large amounts of satellite imagery with a focus on remote sensing of the Geobiosphere and Land System Science.
- Advanced use of cloud-based classification via Google Earth Engine (GEE), and Google Colab.
Please see Absalon course page.
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 machine learning. If you dit not take remote sensing classes, please contact the course responsible prior to enrolling in the class.
