92867 - SURVEY AND MONITORING OF TRANSPORT INFRASTRUCTURES

Course Unit Page

Academic Year 2021/2022

Learning outcomes

At the end of the course, the student acquires the skills to survey and monitor transport infrastructures, from the project phase to the support for their management, using advanced geomatic techniques.

Course contents

The course is organized in two modules and encompasses the following topics.

 

Module 2 (Prof. L. Tavasci)

Review of geodesy: Shape of the Earth - Gravitational Field - Geoid – Heights Definition – Global and Local datum definition and geodetic network positioning – Approximate reference surfaces and coordinate systems.

Principles of positioning: Introduction to Global Navigation Satellite Systems (GNSS) – Pseudorange and carrier phase observables – Single Point Positioning – differential GPS (DGPS) – Real time Kinematic (RTK) – Network for real time positioning (NRTK).

Principles of navigation: Inertial sensor (IMU) – Integration between IMU and GNSS data – Navigation parameters.

 

Module 1 (Prof. E Mandanici)

Review of main cartographic projections and their properties. Geodetic reference frames and their transformations, from local surveys to international systems.

Basics of Geographical Information Systems (GIS). Analysis operators on vector and raster datasets.
Georeferencing of digital maps by GIS software. Practical examples of GIS applications.

Principles of airborne (LiDAR) and terrestrial laser scanning (TLS). The workflow of laser data processing. SFM for close-range photogrammetry. Integration of laser data in mobile mapping systems (MMS).

Teaching methods

The lectures will be supplemented with practical exercises on the field and in class using commercial and open source software packages. These activities are structured so that during each session students will be able to produce practical solutions to the theoretical problems outlined during lectures.

Assessment methods

The final examination consists of a written test with possible oral integration.

Teaching tools

Slides or multimedia tools are used for the lectures in classroom.

Practical exercises are carried out on students’ personal computers, using preferably open source software.

The Virtuale didactic platform is used.
