It is an introductory course for the modern satellite techniques used in Geosciences, together with advanced issues on the use of Geographical Information Systems (GIS) on processing and analyzing satellite data. Scope of the course is to introduce the students to the basic elements of the new satellite techniques, familiarize them with specific satellite systems of Earth observations, and systems dedicated to navigation (GNSS/GPS) and various ground observations (ie using satellite radar data). Additionally, the course aims to demonstrate and train the students on the use of GIS software to process and interpret satellite data for various applications, focusing on geophysical, geological, geotectonic and environmental issues, as well as on natural and anthropogenic hazards. Emphasis is given on the use of “open source” software packages for the processing of the satellite data.
Satellite systems for Earth Observations (EO): Historical review and basic concepts of space based EO systems; Elements of the EM theory, atmospheric effects on the radiation, Energetic and passive EO satellite recording systems, Characteristics of satellite images; Earth Observation Satellite Systems: Orbit and satellite characteristics; Spatial, temporal, spectral discrete analysis; Type of sensors; Processing and analysis of satellite images, type of corrections; Satellite Images photo-interpretation – tectonic, geological, geomorphological and other data recognition; Interpretation of satellite data with open source software packages (i.e. interpretation of optical images LΑΝDSΑT, IKΟΝΟS, QUICKBIRD, SPΟT etc.); Geographical Information Systems (GIS) and Web GIS in geological and geophysical research and geoenvironmental problems – natural hazards. Data base organization and processing of geodata, thematic layers, maps and diagrams creation. Time series creation; Digital Elevation Models and terrain analysis data. Uses in geological and geophysical research as well as in geoenvironmental problems – natural hazards; Satellite Radar Systems. Basic principles of satellite Synthetic Aperture Radar (SAR) Interferometry. Techniques of processing satellite radar images (ie Differential interferometry, Permanent Scatterer interferometry). Applications of radar interferometry for ground deformation observations caused by natural and anthropogenic processes, and mapping flood areas; Global Navigation Satellite System (GNSS/GPS): basic principles; type of GNSS constellations; type of measurements; processing of raw data, error reduction, processing strategies, data collection and data management, use of commercial and open-source s/w to process raw GNSS data.
