Learning outcomes
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.
Course contents
The course is organized in two parts.
First Module
GEODESY
Shape of the Earth - Gravitational Field - Geoid - Heights Definition – Global and Local datum definition and geodetic network positioning - Reference Systems and Reference Frames – Approximate reference surfaces and coordinate systems - Geoidal Undulation.
POSITIONING
Introduction to Global Navigation Satellite Systems (GNSS) – Pseudorange and carrier phase observables – Single Point Positioning – Differenced and undifferenced Precise Positioning techniques and introduction to Satellite Based Augmentation Systems (SBAS).
Second Module
MAPPING
Mapping Datum definition – General concepts of mapping projections – Geographical and cartographic coordinate systems – Classification and selection of mapping projections – Scale factor – Mapping deformations – Tissot’s indicatrix – Mercator Projection, Transverse Mercator Projection, Lambert Conformal Conic Projection, Stereographic Projection. Use of cartographic layers in offshore engineering infrastructure design.
Readings/Bibliography
Bibliographic references for home study and further reading materials:
- Slides and notes from the lectures, scientific literature provided in digital format.
- Eliot di.Kaplan & Christopher J.Hegarty, Arteck House, Understanding GPS - Principles and applications
- John P. Snyder (1987), Map Projection – A working manual, U.S. Geological Survey Paper 1395.
Teaching methods
The lectures will be supplemented with practical exercises in both modules.
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 examination at the end of the course is in written form with eventual oral integration concerning the topics of the course.
Teaching tools
Lectures are conducted in the classroom, the teachers use projected slides or multimedia tools.
A part of the course is pursued through practical exercises, carried out also on personal computer equipment of the students by using preferably open source software provided by the teachers.
