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

This introduction to land surveying present, in its first part, in a broad way all the surveying operations (levelling, traversing, survey, setting out) and the associated instruments (levels, theodolite, total station). Then, complements concerning instruments (process, associated errors) as well as complex computational operations (reduction to the ellipsoid, free station, etc.) are discussed.

Learning outcomes of the learning unit

- to get a basic knowledge of surveying operations and practical methods - to get an advanced knowledge of the instruments - to be able to organise a small surveying work - to masterise the diverse corrections that can be applyied to observations

Prerequisite knowledge and skills

The course assumes good knowledge of basic mathematics: geometry, trigonometry, as well as of some elements of general physics: optical and electronic mechanics.

Planned learning activities and teaching methods

In addition to the theoretical course, 4 practical work sessions are organised (problem-based). These will include field work such as a closed levelling, a traverse and a tacheometric site survey and also a setting out.

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

Face-to-face

Recommended or required readings

Course notes are available on eCampus. Numerous recent reference books (mostly in English) are available at the library of earth sciences.

Assessment methods and criteria

Each field work session will be the subject of a written report which is graded. The arithmetical average of these reports will account for 15% in the final assessment. The written examination (problems and computations) is organsied for 35% of the points. The oral examination (theory) is organised for 50% of the points
