Schedule

Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

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

Learning outcomes of the learning unit

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

Prerequisite knowledge and skills

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.

Planned learning activities and teaching methods

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

Mode of delivery (face to face, distance learning, hybrid learning)

Part A

Face-to-face

Part B

Hybrid 50%/50%

Organisational adjustments related to the current health context

Part A

En code orange, les cours seront organisés à distance

Part B

The course is given 100% remotely.

Recommended or required readings

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.

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Part A

Any session :

- In-person

written exam ( open-ended questions ) AND oral exam

- Remote

written exam ( open-ended questions ) AND oral exam

- If evaluation in "hybrid"

preferred in-person


Additional information:

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

Any session :

- In-person

oral exam

- Remote

oral exam AND written work

- If evaluation in "hybrid"

preferred remote


Additional information:

The evaluation has 2 parts:
- 1 full report + appendices and deliverables (dwg, pdf and .xlsx) by email.
- 1 oral presentation (10 minutes) + 10 minutes of questions
The report should be based on the data initially used for the first report (available, as well as template, on eCampus), paying particular attention to propose
- a minimum of 30 pages + appendices - the focus should be on 3D scan processing for plan generation = provide a part that can act as a tutorial - propose advanced quantitative and qualitative analyses supported by various diagrams and graphs (histograms, moustache boxes ...) - the content AND the form must be particularly well done - several illustrations must be included in the report
The defense, based on the report, will evaluate the knowledge related to the following elements
* The spatial data acquisition process * Typical spatial acquisition instruments/methods * Reference surfaces and coordinates * Geodetic systems * Systematic errors * Measurement methods * The planimetric determinations * The principle of laser scanning * Laser Scanning: the errors * Laser Scanning: In practice * Laser Scanning: Assembly (Registration) * Making plans from 3D data * Extracting information from point cloud data * Making maps, plans and 3D reconstructions
