AIMS AND LEARNING OUTCOMES

Upon completion of the course, the student will have acquired the theoretical and practical tools useful for surveying the territory in the local area using traditional techniques and for analyzing and controlling the measurement campaigns carried out.

In particular, the student will be able to:

•     identify the most appropriate instrumentation, measurement schemes, and methods of execution according to the       required accuracies;
•     carry out a survey, paying particular attention to the operating modes of the instrumentation used;
•     process the data resulting from the measurement campaigns;
•     control the quality of the campaigns carried out and the results obtained in compliance with the expected accuracies;
•     integrate traditional surveying with GNSS satellite positioning techniques (addressed in Geomatics 1);
•     frame the survey in the main reference systems (addressed in Geomatics 1);
•     place surveying in the cartography of interest (addressed in Geomatics 1).

Teaching will also develop the following soft skills and competencies (soft-skills):

- teamwork with a collaborative and constructive attitude;
- strategic thinking and critical thinking;
- effective communication and argumentative skills,

which will enable the relevant Open badges to be obtained:

    - functional literacy competency - advanced level
    - personal competence - advanced level
    - social competence - advanced level
    - learning to learn skills - advanced level
    - competence in project creation - advanced level

TEACHING METHODS

The teaching includes lectures (about 16 hours) and exercises (about 8 hours) related to survey experiences carried out in the field and related processing and analysis.

The exercises are particularly useful for learning the operational basics explained in the lecture, processing measurement campaigns, and acquiring the necessary sensitivity for related analyses.

Students who have a valid certification of physical or learning disability recorded at the University and who wish to discuss possible accommodations or other circumstances relating to lectures, teachings and examinations should contact both the lecturer and Prof. Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School disability contact person.

For further details, please refer to the course's AulaWeb page (https://aulaweb.unige.it)

Working students are advised to contact the lecturer at the beginning of the teaching in order to agree on teaching and examination arrangements that, while respecting the teaching objectives, take into account individual learning methods.

SYLLABUS/CONTENT

Traditional topographic instrumentation

Level: observable, constituent parts and rectification conditions, verification, and possible rectification of the instrument. Modes of operation and main effects in height difference determinations with geometric leveling from the mean and reciprocal.

Total station: observables (azimuth directions, azimuth angles, azimuth, zenith angles), constituent parts, and conditions of rectification, verification, and possible rectification of the instrument. Modes of operation and main effects in azimuthal and zenithal angle readings, measurement of distances at variable parallel angles, and horizontal and constant parallel angle stadia. Electronic distance meter: observables and principles of operation, modes of operation.

Elements of treatment of observations

Concepts of error, statistical variable and random variable, the concept of mean and variance, and their descriptive meaning. Transformation of random variables: the approximate transformation of mean and variance for multi-dimensional, linear, and nonlinear variables. Concepts of redundancy of observations and their compensation by least squares estimation criterion. Applications to major topographic problems with numerical exercises.

Techniques of land surveying metrics

Main schemes of simple and redundant measurements for detailed plan/elevation survey of the built environment and infrastructures framed in the territory, to be carried out with traditional techniques possibly integrated with GNSS positioning. Initial congruence checks of observations. Achievable accuracies. Main areas of work and possible approximations.

EXAMS

EXAM DESCRIPTION

Learning tests will be conducted through self-assessment instruments carried out during the course and, at the end of the course, through written test with some multiple-choice answers, some open-ended answers, and some exercises.Successful completion of an operational test for the positioning of a topographic instrument will be required to enter the written learning test.

ASSESSMENT METHODS

The written test will verify the ability to interpret a problem to reach its solution, with particular attention to the setting of the procedure, the numerical solution and the level of approximation to be adopted.

The written test will test knowledge of some basic concepts, and the ability to interpret a problem in order to arrive at its solution, with particular attention to the setting of the procedure, the numerical solution, and the level of approximation to be adopted. The practical test is aimed at verifying operational skills.
