CODE 95012 ACADEMIC YEAR 2021/2022 CREDITS 4 cfu anno 2 HYDROGRAPHY AND OCEANOGRAPHY 10590 (LM-75) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR ICAR/06 LANGUAGE English TEACHING LOCATION GENOVA SEMESTER 1° Semester MODULES Questo insegnamento è un modulo di: NUMERICAL CARTOGRAPHY AND REMOTE SENSING TEACHING MATERIALS AULAWEB OVERVIEW The course provides the basic tools needed for the spatial knowledge of the territory, through main survey methods and their integrations in different reference frames and maps representations. The course deepens the geomatic approach to the measurement issues following in the remote sensing way. AIMS AND CONTENT LEARNING OUTCOMES The teaching provides the student with some basic concepts on remote sensing, in particular theoretical and practical tools for Photogrammetric, laser scanner tecniques and their integration. Images from different sensors, coming from satellites, aerial or Unmanned Aerial Vehicle, or even terrestrial survey, with the main focus on electromagnetic bands in the spectrum of the visible, are dealt. Particular attention is dedicated to the monitoring criteria. The analysis phase is applied by means of classification techniques in synergy with the course of Numerical Cartography. Several possible applications that will be addressed, to survey littoral area with its infrastructure or to tracking and analysis oceanographic applications. AIMS AND LEARNING OUTCOMES The course provides the basic tools of photogrammetry and laser scanner technique and their integration, properly framed in the reference system with a ground survey, in synergy with the course of Numerical Cartography. Some insights about data processing and analysis will be addressed, in particular to design optimal measuring survey, to process measurement campaigns and to interpret the results. TEACHING METHODS Lectures (26 hours) and practice (14 hours) related to the campaign survey, to the calculation and to the first critical analysis. For the processing procedures, we give priority to the use free and open source software to provide to students. The instrumental and numerical exercises are particularly useful in learning instrumental operating practices discussed in class, in order to the process the measurement campaigns and to the acquire the necessary sensitivity for its analysis. Both applications are needed to compile the technical report that is an integral part of the oral exam. Theoretical lectures followed with practical lectures, held in in English. SYLLABUS/CONTENT Criteria and methods useful to obtain information about the object of the survey from the geometric and radiometric point of views will be discussed. Particular attention is dedicated to the monitoring criteria to observe the evolution of some parameters like morphology, volume, coastline and so on, for example, in a beach area. Main methods of Remote sensing survey approach Theoretical principles of the Photogrammetry and Laser scanner techniques are dealt, to obtain metrical and rdiometric information, properly integrated and framed in the reference system with a ground survey. Analysis of the characteristics, advantages and limits of the main methods of survey and their integration will be illustrated, starting from the main experiences of the Laboratory of Geomatics of the Genoa University. In particular, the optimization of the design of the survey through simulation techniques, the processing of survey campaigns measurements and the analysis of the results will be the main focus of the course. The measurement campaign will lead to the drafting of a technical report to be carried out in small groups of students, in which critically analyze the survey and the resulting outputs. An example of possible applications, that may be subject to the survey campaign, is an integrated survey of a beach in the Genoa area, by photogrammetric, terrestrial laser scanner and/or Lidar survey by UAV (Unmanned Aerial Vehicle). The informatics tools covered in the course will be integrated by open source software; together with the data obtained on the field and during practical lessons, they can be helpful for further analysis and a useful reference for personal study.
