Change Detection

Change detection is the process of identifying differences in a specific area over time. This can involve observing changes in various contexts, such as environmental shifts (like deforestation or urban expansion), shifts in economic indicators, or even changes in public opinion. Techniques used include analyzing images, data, or statistics collected at different times. Change detection helps us understand trends, assess impacts, and make informed decisions in fields like conservation, urban planning, and social research. Essentially, it’s about spotting what has changed and assessing its significance.
