Organisation and examination

Teaching in the first semester, review in January

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

Theory
1. Geometric model of image acquisition made by Pushbroom sensors usually on board Earth Observation satellites
- Examples: HRS sensor on board SPOT5 and Pleiades sensor
- Rigorous geometric model and RPF approximation
2. Automatic detection of homologous point
3. Close range photogrammetry - Direct Linear Transformation
4. Mobile photogrammetry
5. Aerotriangulation
Practical works
The practical lessons on some topics listed above will be performed in complete autonomy. Free software tools or script produced in our unit will be operated. In the latter case, students will have access to Matlab and Octave codes. They thus have a tool they can change at will.
Students should then write a report on their experiment. The report will serve as the basis for the certificational evaluation.

Learning outcomes of the learning unit

* Exploitation of the skill acquired during the introductory course of photogrammetry.
* Awareness and knowledge of the diversity of geometric models of stereoscopic images acquisition by the example of pushbroom system.
* Become aware of alternatives for internal orientation concepts of relative and absolute being introduced by the example of the DLT only operator provided sufficient photogrammetric collinearity to resolve any problem.
* Improve its photogrammetric skill to independently manage an operational photogrammetric project in a professional environment with the necessary rigor and thanks to a perfect understanding of the techniques by adopting professional software solutions that are generally available in this area or designing its own solutions.

Prerequisite knowledge and skills

This course of supplement of photogrammetry can only be followed if the exam on the introductory course was successful.
Like the latter, this course of supplement of photogrammetry uses many concepts of mathematics (geometry and matrix algebra). Notions of least squares adjustment from numerical and statistical methods are another prerequisite. Several concepts of remote sensing are also exploited.
Finally, the way of thinking and analytical rigour developed during scientific courses of the Bachelor degree and secondary studies also constitute an advantage for those attending this course and who wish to reach the required performance level in the professional world.

Planned learning activities and teaching methods

The theoretical part of this course will briefly provide the students with the information needed to carry out the practical exercises on various topics.
The practical works are carried out autonomously and consist of the handling software tools available to students. The focus will be on tools developed in our unit and the adaptation of Matlab and Octave scripts distributed or the implementation of new scripts.
It is obviously recommended to the student to collect the technical and scientific documentation necessary for the realization of the exercises.
To obtain information on access to several software programs, they can consult the following web address: http://www.gitan.ulg.ac.be/cms.
If they wish to get access to classrooms of building B5a to develop their practical work project, they can contact the staff of the Geomatics Unit.

Mode of delivery (face-to-face ; distance-learning)

This is a classroom teaching. The presence is mandatory. Any absence must be justified (by a medical certificate, for example).
The theoretical lessons will consist in "short scientific communication" on each topic. The practical works are carried out autonomously. They will be held in the room B5a/2/35 or B5a/4/18 according to the provided schedule (http://www.facsc.ulg.ac.be/cms/c_253095/fr/horaires).

Assessment methods and criteria

The certificational evaluation is made orally as a discussion of the practical works report produced by the student.
The assessment criteria are as follows: clarity, coherence, logic, rigor, precision, completeness, brevity, relevance, cross-cutting nature (within the course and between courses), quality of mathematical interpretations (mathematical meaning of the different coefficients of the equation, e.g.), physical interpretations (dimensions and units, order of magnitude - scaling, e.g.) and geographical interpretations (single and multivariate spatial and temporal interaction - type - and meaning of the variables e.g.).
Critical thinking with respect to the data used (qualification, nature, meaning, representativeness normalization ...) and methodological choices (justification of choice of methods, adopted thresholds ...) will also be taken into account when evaluation. Furthermore, answers will also be evaluated based on the quality and the originality of the graphic illustration since graphic expression is the scientist's specificity. It further allows demonstrating a good understanding of the phenomenon. Finally, enriching an answer with a wide personal scientific culture will also be considered a factor of excellence in the assessment.
