93221 - Geomatics (1) (LM)

Learning outcomes

At the end of the course the student acquires full skills in the investigation of land properties, about both the natural and anthropogenic properties, through an integrated and systemic approach able to select realiable tools and techniques to acquire, integrate, treat, analyze, archive, and distribute georeferenced space data with continuity on digital media.

Course contents

Basics about geodetic measurements

Useful basics: theory of errors and their assessment: fundamentals of probability and statistics. Measurements: Basics of geodesy: introduction to the reference surfaces, geodetic and topographic fields. Angles, distance and elevations.

Traditional horizontal surveys: Traditional and modern instrumentation: theodolites, total stations, diastimeters and surveyor's levels. Instruments. Topographic survey methods: horizontal survey by intersection schemes and polygonal. Densification of network. Definition of quotes. Reference surfaces. Measuring quotes by high precision spirit levelling.

GNSS POSITIONING

GNSS (Global Navigation Satellite System): constellation, ground and users segments. Signal. GNSS observables: codes and carriers. Positioning technologies: absolute, differential and relative methods. Errors. GNSS networks: designing, measurements, data processing and measurements adjustments. Modern spatial geodetic reference frames. Infrastructures of GNSS permanent stations.

TOTAL STATION e LASER SCANNING

Concepts and instruments. Design of laser surveys. Data processing.

Teaching methods

ATTENDING AND NON-ATTENDING STUDENTS

Frontal lessons with in-depth sessions on specific topics. Discussion of case studies where the ability to design and execute a survey intervention is required.

For this course, having a highly applicative characterization, assiduous attendance is required, at least not less than 80% of the lessons.

The horn is NOT recommended for students NOT attending

Assessment methods

ATTENDING AND NON-ATTENDING STUDENTS

 The exam takes place in oral mode. During the interview the Teacher will verify the candidate's knowledge and understanding of the basic concepts of Geomatics and will evaluate his ability to apply them to concrete cases. You will also verify the transversal knowledge of the topics covered by the program and the acquisition of the fundamental technical terms that characterize the subject. Finally, the ability to identify detection methods suitable for solving specific problems will be evaluated.

Please note that the exam methods will be the same for both attending and NON-attending students.

The evaluation criteria that will contribute to determining the final grade will be:

1) the degree of knowledge, depth and critical understanding of the contents;

2) the ability to argue, to establish relationships between topics and to apply theoretical principles to real cases;

3) the ability to present using appropriate basic technical terminology;

4) the robustness of reasoning in evaluating problems.

The grade will be assigned based on the following grading scale:

18-21: sufficient performance;

22-24: fair performance;

25-27: good performance;

28-29: very good performance;

30: excellent performance;

30 cum laude: excellent performance.
