Topography

Part A

This introduction to land surveying present in a broad way all the surveying operations (levelling, traversing, survey, setting out) and the associated instruments (levels, theodolite, total station).

Part B

This partim B to land surveying presents complements concerning instruments and other 3D measurments techniques

Part A

- to get a basic knowledge of surveying operations and practical methods - to get a basic knowledge of the instruments - to be able to organise a small surveying work - to be able to exchange with geomaticians

Part B

- to get an advanced knowledge of the instruments - to be able to perform a small surveying work - to masterise the diverse corrections that can be applyied to observations

Part A

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

Part B

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

Part A

In addition to the theoretical course, 3 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 a setting out.

Part B

In addition to the theoretical course, a practical work is organised

Part A

Face-to-face

Part B

Part A

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

Part B

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

Part A

Each field work session will be the subject of a written report which is graded. A written examination is organsied and eventually, an oral examination is organised. The whole evaluation process is described in the course's overheads.

Part B

The evaluation process is explained during the first course

Part A

Part B

The assessment will be based on:

• a complete report in response to the issues proposed in the document available on the eCampus space, and whose instructions are explicitly described (30%)
• the quality of the data deposited on the DoX space provided for this purpose (instructions in the eCampus space ) (30%)
• a video conference presentation of the results (40%)
