Remote Sensing Applications and Techniques

The video tutorial by Igor Prikazuk explores the history and applications of earth observation, starting from aerial photography in the 1860s to modern satellite imaging. It highlights the evolution of technology from hot air balloons to satellites and discusses the various applications of remote sensing in weather prediction, water management, and land monitoring. The video also introduces the Synthetic Crosstak consortium, which supports scientific collaboration and training in remote sensing.
