Specific Foundation / Core

Upon successful completion, students will have acquired the following knowledge and skills: ● Knowledge of aerial photo orientation and photo-mosaic creation. ● Photo-interpretation skills. ● Making measurements on aerial photographs (photogrammetry). ● Ability to read and create maps from aerial photographs. ● Acquire basic knowledge of pre-processing and analysis of multispectral satellite data.

Introduction to Aerial Photography (AP) and the historical development of Remote Sensing. Fundamentals of radiation and characteristics of the electromagnetic spectrum (radiation laws, parts of the electromagnetic spectrum, path of radiation, atmospheric effects, interaction of radiation with atmosphere and objects, categories of radiation scattering, spectral identity of objects). Aerial photography instruments and means of aerial photography planning (aerial photography systems, categories of aeroplanes, camera elements, focal length, filters, categories of cameras, flight map, flight time and altitude, ways of acquiring AP). Aerial photography geometry and scale (vertical and oblique AP, characteristics of AP, photo-stationary points and active surface, expressions of scale – point scale and average scale). Displacement, stereoscopic parallax, radial triangulation – Stereoscopic observation (the concepts of deformation and displacement in an AP, calculation of displacement and object height, the concept of depth, stereoscopic observation, types of stereoscopes, the concept of parallax). Principles of photointerpretation (basic concepts and stages of photointerpretation, basic elements and principles of photointerpretation – object recognition, support of photo-interpretation processes, use of stereograms). Horizontal and vertical measurements (measurement of angles, area distances in AP, measurement of heights using parallax and shadow length, direct and indirect measurements of forest parameters). Measurements of various parameters of trees and forest stands. Orthophotography, orthophotomaps (orthographic positioning of AP, advantages of using orthophotography, production of digital orthophotomap and orthophotomap). Basic principles of digital image analysis (satellite and aerial imaging, spectral indices, detection of changes through spectral index differences). Taking in situ reflectance measurements. Forestry applications of optical remote sensing data. The practical training is carried out with specialized scientific instruments, as well as with the use of specialized open-source computer software.
