The aim of the course is to provide knowledge and skills to understand and critically evaluate the subsequently steps from the survey to the representation of the building and its infrastructure: choice of the reference system, selection of the appropriate instruments, design of the survey, data collction, evaluation of the results, cartographyc representation. The course includes lectures and exercises.
An inductive approach to the topics covered is proposed. Techniques and tools are shown to students, as well as their application to real case studies. The theoretical and methodological aspects are discussed in depth during the lessons of the course.
Frontal lessons alternate with practical and computational exercises.
All information and material related to lessons and exercises are available on the Moodle platform
Type of Assessment
Written test and oral interview. Delivery of intermediate exercises.
Geodesy: the equipotential surfaces and the geoid; the geometry of the ellipsoid. Coordinate systems and transformation between local ellipsoidical, geocentric and cartesian coordinates. Geodetic reference systems (global and local), elevation systems and differences in height.
Cartographic representations and maps. Cartographic projections. Official Italian cartography. Numerical cartography and its evolution.
Geographic information systems. Databases: geographical and alphanumeric components. GIS tools: topological operators and queries. Interoperability and representation: INSPIRE directive and OGC services. Future prospects: from GIS to BIM.
Satellite positioning techniques. The GNSS system: system architecture, signal structure, observable differentiation techniques. Design and execution of a survey, use of softwarefor data processing and analysis of the accuracies achievable with different methodologies.
Modern topographic instruments: principles of operation and use of autolevels, digital levels, total stations.
Elementary survey schemes: measurement of differences in height, azimuthal and zenithal angles and distances. Processing of data acquired on the field.
Measurements and compensation of networks and traverses: materialisation, survey and planimetric and altimetric compensation.
Terrestrial scanning systems. Data alignment and georeferencing. DEM and DSM.
Digital aerial and terrestrial photogrammetry. Camera network project and flight plan for the drone. Orientation of the images. Scaling and georeferencing of the model. Graphic outputs.
