Nominal workload:125 hours.

Teaching and exam period:The course starts in the June block. The course has teaching/evaluation in the June block.

About this course

Lectures: The geometric and radiometric properties of satellite imagery. Geometric rectification/geocoding. Single-image photogrammetry with emphasis on SPOT scenes. Control of geometric accuracy. Special image enhancement techniques (Filtering, Principal component analysis, Fourier transformation). Image mosaic production. Classification methods with emphasis on unsupervised classification. Use of satellite images for vegetation mapping.

Exercises: 1) Geometric rectification and accuracy evaluation. Exploratory analysis of airborne lidar data. 2) Unsupervised classification (clustering) of lidar intensity and other remotely sensed data. 3) Training data collection, supervised classification of satellite images and accuracy evaluation

Excursion: Field work in the Follo/Oslo region.

Learning outcome

The students will have acquired substantial knowledge of the most central ideas connected with the characteristics of aerial and satellite images, digital image processing methods that are relevant in geomatics, as well as be able to carry out such types of image processing, interpretation and analysis using selected image processing tools (currently CATALYST). The students will be acquainted with the process of obtaining raw satellite images, evaluate the quality of the images, (pre)process them, collect ground data, extract some information through processes such as image classification and evaluate the accuracy.
  • Learning activities
    Lectures, lab exercise and field exercise.
  • Teaching support
    Learning support will primarily be given in connection with the part of the structured time that is allocated to exercise supervision. It will also be possible to make appointments with the course instructor within office hours.
  • Prerequisites
    GMBB100/GMFM100
  • Recommended prerequisites
    GMGI102
  • Assessment method
    Project report

  • Examiner scheme
    The external and internal examiner jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidate¿s exams as a calibration according to the Department's guidelines for examination markings.
  • Mandatory activity
    Mandatory exercises and excursions.
  • Notes
    Minimum 5 students
  • Teaching hours
    Lectures: 30 hours. Exercises: 40 hours. Excursion/field exercise: 8 hours.
  • Admission requirements
    Special requirements in Science
