AIMS AND CONTENT

LEARNING OUTCOMES

Introducing the key concepts associated with Earth observation through remote sensing images for renewable energy applications. Providing the students with basic knowledge about remote sensing image acquisition and about mapping, through remote sensing image analysis, bio/geophysical parameters associated with renewable energy sources, including vegetation biomass, wind velocity field over sea water, solar irradiance, and air surface temperature.

AIMS AND LEARNING OUTCOMES

Specific objectives of the course include providing the students with basic notions about: remote sensing data collected by optical, radar, and laser sensors; vegetation biomass mapping from remote sensing; wind velocity field characterization over sea water from radar data; solar irradiance retrieval from geostationary optical data; air surface temperature estimation from thermal infrared data; and methodological basis of vegetation cover classification and supervised regression.

TEACHING METHODS

Class lectures (approximately 38 hours) and software laboratory exercises (approximately 10 hours).

SYLLABUS/CONTENT

1. Introduction to remote sensing for Earth observation: remote sensing and its applications in the energy field; spaceborne and airborne sensors and platforms; spatial, spectral, temporal, and radiometric resolutions; digital remote sensing images, their visualization, and contrast enhancement.
2. Remote sensing image acquisition: active radar imaging sensors, side-looking airborne radar and synthetic aperture radar; passive multispectral sensors; examples of space missions for Earth observation; calibration, georeferencing, and image registration; active laser sensors (LiDAR) and 3D data collection.
3. Vegetation biomass estimation through remote sensing: direct and indirect approaches; direct biomass estimation as a supervised regression problem; indirect biomass estimation through the mapping of vegetated land cover and the modeling of 3D structure; vegetated land cover mapping as an image classification problem; basic concepts of statistical pattern recognition; recalling probability theory and random variables; examples of non-contextual remote sensing image classifiers; 3D modeling using LiDAR data; applications to vegetation biomass retrieval at various spatial resolutions.
4. Wind velocity estimation over sea water through remote sensing: wind velocity over sea and ocean, small-scale roughness, and relationship to radar remote sensing; scatterometry-based methods for the estimation of wind velocity; application to siting offshore eolic systems.
5. Solar irradiance and air temperature estimation through remote sensing: estimation of irradiance and irradiation from visible imagery; clear-sky model; cloud cover indices; air temperature regression from thermal infrared imagery; application to the siting and monitoring of photovoltaic systems.
6. Denoising and filtering remote sensing images: noise and speckle in remote sensing images; denoising through linear and rank filters; multilooking and despeckling; applications to biomass mapping.
