Learning unit contents

The course provides an introduction to various data acquisition methods used in geography. It emphases practice and field work basics.
The course consists of two parts. The aerial photography part is taught by Y. CORNET. The one dedicated to survey and plans is taught by R. BILLEN.
Aerial Photography (Part Y. CORNET)
- photography (analogical, digital, light radiation, ...)
- central projection,
- scale,
- parallax and stereoscopy (binocular vision, stereoscopes, anaglyphs)
- photogrammetry,
- examples of use (relief, cities, crops...).
Topographic survey and plans (Part R. BILLEN)
- measuring tape, square prism, plans covering, contour lines
- introduction to direct and trigonometric leveling
- presentation of advanced techniques.

Learning outcomes of the learning unit

The purpose of this course is mainly to awaken the student to some simple data acquisition tools he will use later in his training.
Aerial photography: The student will master the geometric aspects of aerial photographs (geometric model: central projection). From practical examples, he will also demonstrate his understanding the opportunities offered by stereoscopy in different fields of geography (restitution by visual interpretation and metrology).
Topography: The student will be able to organize a small mission with traditional measurement tools and to represent the results graphically. He will be able to understand the limitations of these techniques and to foresee the benefits of new methodologies.

Prerequisite knowledge and skills

The prerequisites for this course are fundamental concepts of mathematics (geometry and trigonometry) and physics (geometrical optics and electromagnetic radiation).

Planned learning activities and teaching methods

The course includes theoretical parts (aerial photography, topography) delivered ex cathedra. The theoretical concepts will then be illustrated and operated (measurements, calculations, interpretation) during practical sessions (analysis of photography under a stereoscope or computer, land survey, etc.).

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

The method of teaching used is face-to-face. Presence is mandatory. Any absence must be justified (by a medical certificate, for example).

Other bibliographical information will be provided during the lessons.

Assessment methods and criteria

Final evaluation is a combination of the evaluation of Prof. Cornet part and of the evaluation of Prof. Billen part. The student must have at least 10 for each evaluation. In this case, the final evaluation is the mean of the two evaluations. At the contrary, the final evaluation is the lowest evaluation of both parts.
Prof. Cornet Part
- Non-certificational self-assessment: Exercises done and corrected during practical sessions providing feedback to the student thanks a strong interaction between students and teachers.
- Certificational evaluation: Oral examination on theory and written examination based on exercises inspired by non-certificational evaluation.
Prof. Billen Part
- Non-certificational self-assessment: On-field Exercises.
- Certificational evaluation: reports about on-field exercises and written practicals for the practical evaluation, written exam and MCQ for theoretical evaluation.
