GMFM300 Remote Sensing II - Analysis

Lectures: Image formation, pixel representation and image formats. Spaceborne imaging principles (platforms, sensors, orbits). Satellite image radiometric and geometric properties. The use of GPS for control point determination. The use of matching for controlling the geometric accuracy of satellite images. Satellite image orthorectification and terrain model generation from satellite image optical stereo. Spectral signatures and indices. Principles and methods of image classification, change detection and movement analysis using satellite images. The use of lidar data in thematic mapping. Principles of Imaging Synthetic Aperture Radar (SAR) and Interferometrical use of SAR.

Exercises:1: Determination of the structure of image files with unknown formats. Import, processing and converting of image files. 2: Orthorectification and automated terrain model production from satellite optical stereo and further analysis. 3: Self-guided mini-project focusing on image classification, change detection and visualization.

Excursion: A visit to relevant research, education, and business establishments located in the region.

the region.

Knowledge: After completing the course, the students will have obtained substantial understanding of the principles of remote sensing image acquisition techniques and image characteristics. They will also get insight into the analysis methods of different remote sensing types (mainly optical but also radar and lidar) for selected real-world problems such as terrain model creation, image classification for mapping purposes, change detection and terrain movement analysis.

Skills: Students will be able to retrieve remote sensing images, evaluate their quality and specifications. They will also be able to orthorectify a raw satellite image, derive digital terrain model from optical stereo images. They will gain diverse skills in image classification, change detection and image matching methods through exercise sessions and individual mini-projects.

General Competence: The lectures form the foundation for methods and techniques and ensure that the relevant examples link theory and practice together. The exercises help the students acquire practical skills in connection with the methods and techniques covered in the lectures. The excursion supplements the other teaching and provides knowledge of relevant practice and relevant problems. Additionally, the students will enhance their report writing and communication skills, experience formulating, planning and implementing a mini-project that prepares them for their thesis and for the job market.
