Conoscenze e abilità da conseguire
Through this course the student acquires knowledge to integrate modern surveying technologies offered by Geomatics for the metrical study of objects, sites, and territory in a consistent way. The student learns the use of space-geodetic techniques suitable for multi-scale measurements (global to local), and thus he is able to integrate in situ observations, airborne surveying and satellite imagery. 3D data acquisition and modeling is in particular discussed, either for environmental applications and for civil and architectural surveys.
Contenuti
In the first module of the course are reviewed fundamentals of
Space Geodesy and Satellite Positioning. International references
frames and their transformations. Introduction to Global Navigation
Satellite Systems (GNSS). Land Surveying, and integrated
networks. Field procedures and data analysis.
The second module begins with a review of Geomatic Methods for 3D
data acquisition. Basic Elements of Digital Terrain Modeling (DTM)
and main applications in Civil Engineering, Surveying and
Photogrammetry, Earth Science, Planning and Resource Management.
Surface Representation from Point Data. Interpolation: Global and Local Methods. Kriging. Gridding and Grid Resampling, Search Algorithms in Gridding and Interpolation.
TIN and Grids: comparison of data structures. Filtering and smoothing of gridded data. TIN data, Voronoi Diagrams and Delaunay Triangulation, methods for TIN construction.
DTM manipulation and DTM Derivatives (Slope Maps, Aspect maps, Viewsheds, Watersheds). Volume computation, contours, drainage networks.
Basics of Geographical Information Systems (GIS). Analysis operators on vector and raster datasets. Environmental modeling in GIS environments, use of DTM and satellite imagery in GIS.
Practical examples of GIS applications (resource allocation, risk analysis, environmental monitoring and modeling by GIS, change analysis).

Metodi didattici
The lectures will be supplemented with practical exercises on the field and in the computer lab (by commercial and open source software).
These activities are structured so that during each session students will be able to produce practical solutions to the theoretical problems outlined during lectures.
Modalità di verifica e valutazione dell'apprendimento
The examination at the end of the course is in written form with
eventual oral integration, and aims to assess the achievement of
learning objectives related to:
- Space Geodesy, Reference Frames, Geodetic Monitoring
- Digital Terrain Modeling
- GIS modeling for environmental applications
Strumenti a supporto della didattica
Lectures will be conducted both in the classroom and in the computer lab. The teacher will use both the blackboard and projected slides or multimedia tools. A part of the course will be pursued through practical instrumental exercitations, carried out also on the computer equipment of the students by using open source software.
