Prerequisites : Notions of statistics, general physics course.
The course has three components:
1: The presentation during lectures of the theoretical and methodological bases of remote sensing;
2: The application of image processing and interpretation methods to Landsat data on a region of Belgium, using image processing software on PC;
3: The exploration of a large range of remote sensing applications and of the methods used in each application, on the basis of CD-ROMs demonstrating case studies.
Physical bases of remote sensing:
- Definitions: radiant energy, radiant flux, radiant flux density, radiance;
- Interactions between energy and the surface of the earth: laws of Stefan-Boltzmann and Wien.
- Spectral reflectance curves ;
- Atmospheric effects;
- Physical interactions with thermal infra-red energy.
The sensors used in remote sensing:
- Landsat MSS and TM, SPOT;
- AVHRR, Vegetation, MODIS;
- the new high spatial resolution sensors.
Image processing:
- Corrections for non-systematic and systematic geometric distortions
- Radiometric corrections
- Extraction of statistics from images
- Contrast enhancement
- Spatial filtering
- Supervised classification
- Unsupervised classification
- Classification errors estimation
- Change detection methods
- Multispectral transformations: Tasseled cap transformation; principal components analysis;
- Notions of microwave remote sensing.
Practical work:
Processing of a Landsat TM image of Belgium:
1st session Introduction to image processing software
2nd session Color composites and contrast enhancement
3rd session Design of a scientific project
4th and 5th sessions Geometric correction
6th session Unsupervised classification
7th session Supervised classification
8th session Accuracy assessment of classification

| Aims |
Knowledge : The students will acquire a good knowledge of the different applications of remote sensing, and a capacity to decide which sensors and which image processing and interpretation methods are most appropriate for a given application.
Skills : The students will gain understanding of the bases of remote sensing and will be able to process and interpret satellite data on a given region, using a image processing software on PC. Emphasis is put on optical remote sensing for terrestrial ecosystem applications.

Continuous evaluation based on:
- Two tests during the trimester: (i) physical basis of teledetection and (ii) image processing technique (10% of final result for each test, so 20% for both);
- two practical work reports for each processing step (30% of final result for the overall of reports);
- a work on teledetection applications: answer to several questions, based on CD-ROMs (20% of final result).
Final evaluation: based on written examination (30% of final result).
