Course program
Lecture contents: The process of remote sensing; electromagnetic radiation, the electromagnetic spectrum, radiometric quantities; interaction of radiation with the atmosphere (absorption and scattering); Interaction of radiation with the earth's surface (reflectance and spectral signature); remote sensing sensors (active and passive); remote sensing platforms; remote sensing data processing, image processing (image pre-treatment and enhancement) image transformation, image classification (automatic, supervised and unsupervised). Applications: study of vegetation and land use.
Principles of aerophotogrammetry, soil quality, landscape unity; basic elements, tools, techniques and procedures of photointerpretation; aerial photography products; evaluation of land cover and land use. Applications of photo-interpretation (creation of basic cartography, land use maps, geomorphological maps, landscape units).
Contents of the exercises: interpretation of aerial photographs using a stereoscope, interpretation of satellite images with different spatial resolution, data collection in the field and processing in a GIS environment, retrieval, use and transformation of data from various satellite platforms.
