| Course contents : | In examining the historical evolution of materials and methods of increasing resolution in topometry, this course will first offer a number of definitions, especially as regards plane projection. Next, the course will examine basic instruments for the direct measurement of horizontal distances and perpendicular alignments.
Modern instrumentation is covered through the description of the essential parts of instruments: the vernier, the micrometer, the level and the loupe.
A long chapter is devoted to direct measurement by level, and to different kinds of levels.
Next, the modern planimeter is introduced in relation to the measurement of angles and distances, in which the main point of emphasis is the means of eliminating the largest part of instrumental error.
With regard to methods, the course deals with systems of reference and means of calibration. |
|
| Course objective : | Alongside cartography, geodesy, remote detection and photogrammetry, this course also covers one of the elements of geomatics.
It aims to enable students to practice both planimetry and altimetry topography while keeping instrumental and systematic errors to a minimum. |
|
| Prerequisites : | The course assumes good knowledge of basic mathematics: geometry, trigonometry, algebra, analysis, numerical calculus, as well as of general physics: optical and electronic mechanics. |
|
| Workshops : | The 4 practical work sessions begin at the end of the theory course and will follow one another until the end of the quarter. These will include field work such as a closed levelling, a triangulation and a tacheometric site survey.
These will be the subject of corrected and graded reports. |
|
| Organization : | The course takes place in the first quarter at the Institut de Physique (B5). An interval lasting a few minutes is anticipated in the middle of each session. Numerous overheads and slides will illustrate the presentations. Each instrument described is presented directly to the audience, who can, where possible, handle the instruments.
Practical work begins at the end of the theory course. |
|
| Written notes : | Course notes are available in the form of an edited publication by the Editions de l'Université de Liège (ISBN 2-930322-09-8).
Numerous recent reference books (mostly in English) are cited in the bibliography given at the end of this publication. |
|
| Assessment : | Each field work session will be the subject of a written report which is graded. The arithmetical average of these reports will account for a quarter of the points in the final assessment. The oral examination includes a question and several sub-questions. Passing the oral examination is required in order to achieve a passing grade overall. |
