Image analysis

Definition

Image analysis is the process of inspecting and interpreting visual data from images captured by various remote sensing technologies. This method allows meteorologists to extract meaningful information about atmospheric conditions, weather patterns, and environmental changes by processing and analyzing satellite or aerial imagery. It plays a vital role in enhancing our understanding of weather phenomena and forecasting.
